Definitions

  • the present invention relates to compositions such as cleaning compositions comprising an enzyme having DNase activity and at least one perfume compound.
  • the invention further relates to use of the detergent compositions in cleaning processes and/or for deep cleaning of organic stains, to methods of using said compositions for removal or reduction of components of organic matter, and to methods for increasing binding of a perfume to a textile, for boosting the effect of perfumes in detergent compositions, for increasing perfume retention on a textile and for producing perfume-containing compositions with a reduced amount of perfume.
  • perfumes may be chemical compounds or e.g. natural oils such as essential oils and other natural compounds.
  • the perfumes often have a double function of providing a desired scent and masking undesirable odors, which may stem from the detergent itself or from the fabric.
  • perfume in laundry detergents has faced several challenges. For example, may perfume components are released very quickly, thus the “freshness” effect of perfume often does not last very long.
  • perfume allergy there is a trend to use detergents containing less or no perfume.
  • perfume is expensive and can represent a significant factor in the overall cost of e.g. laundry detergents.
  • Enzymes have been used in cleaning compositions for decades. Usually a cocktail of various enzymes is added to cleaning compositions, wherein each enzyme targets a specific substrate, e.g. amylases are active towards starch stains, proteases on protein stains and so forth. The effectiveness of these commercial enzymes provides cleaning compositions which remove much of the soiling.
  • components of organic matters such as biofilm and extracellular polymeric substances (EPS) constitute a challenging type of staining due to the complex nature of such organic matter, and commercially available cleaning compositions are generally not able to effectively remove or reduce EPS and/or biofilm related stains.
  • EPS extracellular polymeric substances
  • Textile surfaces and hard surfaces such as dishes or the inner space of a laundry or dishwashing machine enduring a number of wash/cleaning cycles, become soiled with many different types of soiling which may be composed of proteins, grease, starch etc.
  • Some types of stain may be associated with organic matter such as biofilm, EPS, etc. , which may be composed of different molecules such as polysaccharides, extracellular DNA (eDNA), and proteins.
  • Some organic matter comprises an extracellular polymeric matrix, which may be sticky or gluing, which when present on textiles attracts soils and may cause redeposition or backstaining of soil, resulting in a greying of the textile.
  • organic matters such as biofilms often cause malodor issues as various malodor molecules can be adhered by the polysaccharides, extracellular DNA (eDNA) and proteins in the complex extracellular matrix and be slowly released to cause a noticeable malodor.
  • WO 2014/08701 1 WO 2015/155350 and WO 2017/060475.
  • WO 201 1/163325 describes various perfume raw materials, perfume delivery systems and consumer products comprising such perfume raw materials and/or such perfume delivery systems.
  • the present invention is based on the surprising discovery that the use of a DNase in a detergent composition results in an enhanced effect of perfume compounds in the composition that allows for the amount of perfume to be reduced while still maintaining a freshness and cleanliness effect of the perfume on a textile washed with the detergent composition.
  • the present invention relates to detergent compositions comprising an enzyme having DNase activity and at least one perfume compound, as well as to use of a polypeptide having DNase activity in detergent compositions comprising a perfume, e.g. for increasing binding of a perfume to a textile during a laundry process, for increasing perfume retention on a textile after wash, and/or for enhancing the effect of a perfume in a detergent composition.
  • the invention further relates to a method for increasing binding of a perfume to a textile during a laundry process, and/or for increasing perfume retention on a textile, the method comprising washing the textile with a detergent composition comprising at least one perfume compound and a polypeptide having DNase activity.
  • the invention further relates to a method for enhancing the effect of a perfume in a laundry detergent composition, and/or for preparing a detergent composition with a reduced perfume content while maintaining perfume effect after wash, the method comprising preparing a detergent composition comprising at least one perfume compound and a polypeptide having DNase activity.
  • the invention further relates to a method for cleaning an item, wherein the item is preferably a textile, comprising the steps of: a) contacting the item with a detergent composition comprising a polypeptide having DNase activity and at least one perfume compound, and optionally b) rinsing the item.

  • the inventors have surprisingly found that enzymes having DNase activity act synergistically with volatile perfume compounds, resulting in an enhanced binding of perfume compounds to textiles washed with a detergent composition comprise a DNase and one or more perfume compounds.

  • perfume compound refers to a volatile fragrance compound that is suitable for use in a perfume.
  • a “perfume compound” may also be referred to by similar terms such as a “perfume component” or a “fragrance compound”.
  • fragrance includes perfume raw materials and compositions, scents and oils, e.g. essential oils.
  • perfume i.e., perfume
  • compounds such as aldehydes, ketones and esters.
  • plant and animal oils and exudates comprising complex mixtures of various chemical components are known for use as fragrances.
  • a perfume is a blend of volatile compounds with different volatilities which can bind to receptors in the nose and therefore has a smell or odor, usually a pleasant one. These compounds are also known as odorants or fragrances. Most perfumes possess molar weights of up to approximately 200 g/mol, in some cases up to about 300 g/mol. Larger molecules are not volatile enough to be perceived by the human nose.
  • the volatility of a compound describes how readily it vaporizes by way of evaporation or boiling. Perfume compounds vaporize, depending on their volatility, by evaporation at room temperature and atmospheric pressure. Volatility is often described using vapor pressure or boiling point, with a high vapor pressure or low boiling point indicating a high volatility. Although the volatility of a compound is related to its molecular weight, other factors such as structure and polarity also play a role, as does interaction between fragrance compounds.
  • top notes The most volatile fragrance compounds are referred to as top notes or head notes, whereas increasingly less volatile compounds are referred to as heart notes or middle notes, and the least volatile as base notes or back notes.
  • the top notes are responsible for the first impression of a detergent, and the heart notes represent the characteristic smell.
  • the base notes ensure the more substantial, long-lasting effect of the perfume.
  • top, heart (middle) and base notes may be grouped based in different criteria.
  • One such grouping is that of Poucher (Poucher, W. A. (1993).
  • Fragrance manufacturers and sellers provide information about their fragrance compounds such as molecular weight, vapor pressure and boiling point, and may also indicate whether individual fragrance compounds are top notes, middle notes or base notes. Such information is e.g. provided at iff.com/portfolio/products/fragrance-ingredients/online- compendium and at shop.perfumersapprentice.com.
  • top, heart and base notes may also be defined based on retention time (in minutes) in GC-MS performed using the parameters as defined in Example 2 herein.
  • top notes are defined as fragrance compounds that have a retention time in GC-MS of less than 8.76 min
  • heart notes are defined as fragrance compounds that have a retention time in GC-MS in the range of from 8.76 to 16.51 min
  • base notes are defined as fragrance compounds that have a retention time in GC-MS of more than 16.51 min.
  • the presence of a polypeptide having DNase activity in a detergent composition results in an increase in binding and/or retention of top note and/or heart note perfume compounds compared to base note compounds, and thus an increased relative perfume effect for these notes.
  • a detergent composition e.g. a laundry detergent composition or a fabric softener
  • the heart note compounds are increased relative to the base note compounds.
  • the top note and heart note compounds are increased relative to the base note compounds.
  • at least the top note compounds are increased relative to the base note compounds.
  • the presence of a polypeptide having DNase activity in a detergent composition results in an increase in binding and/or retention of top note and/or heart note perfume compounds compared to base note compounds when measured on a polyester material.
  • any given fragrance compound as being a top, heart or base note is not important. Rather, as it will be apparent from the explanation above, it is a question of how a DNase polypeptide in a detergent composition effects the overall binding and/or retention of the different groups of fragrance compounds, where such compounds are broadly classified into the three categories of top, heart and base notes.
  • the odor detection threshold of the fragrance compounds is also important for the perfume functions.
  • the odor detection threshold value is defined as the minimal concentration of a substance that can be detected by a human nose. Thus, compounds with a lower detection odor threshold are more easily detected by humans.
  • the threshold is subjective and may vary, it mainly depends on three factors, the vapor pressure, water solubility and the water/organic solvent (octanol) partition coefficient, which together account for 77% of variance in threshold values (Rodriguez et aL, 2011 , Flavour and Fragrance Journal 26: 421 -428).
  • malodors are also volatile compounds that can bind to receptors in the nose.
  • malodors are perceived as unpleasant.
  • a perfume can interfere with the perception of malodors by competing with the receptors in the nose, thereby masking the malodors.
  • fragrances do not interact with malodors, and malodors are not physically removed or chemically eliminated. Rather, perfume compositions are carefully designed to mask the anticipated malodors.
  • the duration of the “freshness” or “cleanliness” effect provided by a perfume in a detergent composition is influenced by how fragrances and malodors are retained on the washed fabric.
  • Laundry malodors can come from various sources, including human body odor as well as malodors from the environment such as kitchen odors, cigarettes, food stains, etc.
  • Another important source of malodors is from microbes present in the textile, which can metabolize the substances transferred from the human body (sweat, dead cells, sebum, etc.) and generate malodors during drying, storage or wearing (Bockmuehl et aL, 2019, Microbial Cell 6: 299-306).
  • Fiber type also plays an important role in retaining and release of odor compounds, e.g. malodor compounds may be more effectively removed from cotton than from polyester. This is partly related to the polarity (hydrophilicity) of the odor compounds and that of the textile fibers, with cotton containing mainly highly polar cellulosic fibers, while fibers of polyester and wool are relatively non-polar compared to cotton fibers.
  • polarity hydrophilicity
  • the order of compound polarity of perfume compounds from high to low is as follows: Amide > Acid > Alcohol > Ketone ⁇ Aldehyde > Ester > Alkane.
  • “invisible dirt” present on the textile also affects odor retention.
  • Used textiles often contain human secretion (e.g. sebum, keratin) and microbial soil (e.g. biofilm, DNA, carbohydrates), which may not be visible but which contribute to binding of odor compounds on the textile.
  • human secretion e.g. sebum, keratin
  • microbial soil e.g. biofilm, DNA, carbohydrates

Description

USE OF POLYPEPTIDES HAVING DNASE ACTIVITY
Reference to a Sequence Listing
This application contains a Sequence Listing in computer readable form, which is incorporated herein by reference.
BACKGROUND OF THE INVENTION
Field of the invention
The present invention relates to compositions such as cleaning compositions comprising an enzyme having DNase activity and at least one perfume compound. The invention further relates to use of the detergent compositions in cleaning processes and/or for deep cleaning of organic stains, to methods of using said compositions for removal or reduction of components of organic matter, and to methods for increasing binding of a perfume to a textile, for boosting the effect of perfumes in detergent compositions, for increasing perfume retention on a textile and for producing perfume-containing compositions with a reduced amount of perfume.
Description of the Related Art
Cleaning compositions comprising one or more perfumes are well-known. Perfumes may be chemical compounds or e.g. natural oils such as essential oils and other natural compounds. The perfumes often have a double function of providing a desired scent and masking undesirable odors, which may stem from the detergent itself or from the fabric.
However, the use of perfume in laundry detergents has faced several challenges. For example, may perfume components are released very quickly, thus the “freshness” effect of perfume often does not last very long. In addition, with the increasing awareness of perfume allergy, there is a trend to use detergents containing less or no perfume. Furthermore, perfume is expensive and can represent a significant factor in the overall cost of e.g. laundry detergents.
Enzymes have been used in cleaning compositions for decades. Usually a cocktail of various enzymes is added to cleaning compositions, wherein each enzyme targets a specific substrate, e.g. amylases are active towards starch stains, proteases on protein stains and so forth. The effectiveness of these commercial enzymes provides cleaning compositions which remove much of the soiling. However, components of organic matters such as biofilm and extracellular polymeric substances (EPS) constitute a challenging type of staining due to the complex nature of such organic matter, and commercially available cleaning compositions are generally not able to effectively remove or reduce EPS and/or biofilm related stains. Textile surfaces and hard surfaces, such as dishes or the inner space of a laundry or dishwashing machine enduring a number of wash/cleaning cycles, become soiled with many different types of soiling which may be composed of proteins, grease, starch etc. Some types of stain may be associated with organic matter such as biofilm, EPS, etc. , which may be composed of different molecules such as polysaccharides, extracellular DNA (eDNA), and proteins. Some organic matter comprises an extracellular polymeric matrix, which may be sticky or gluing, which when present on textiles attracts soils and may cause redeposition or backstaining of soil, resulting in a greying of the textile. Additionally, organic matters such as biofilms often cause malodor issues as various malodor molecules can be adhered by the polysaccharides, extracellular DNA (eDNA) and proteins in the complex extracellular matrix and be slowly released to cause a noticeable malodor.
Cleaning compositions and detergents comprising enzymes having DNase activity have been described e.g. in WO 2014/08701 1 , WO 2015/155350 and WO 2017/060475. WO 201 1/163325 describes various perfume raw materials, perfume delivery systems and consumer products comprising such perfume raw materials and/or such perfume delivery systems.
The present invention is based on the surprising discovery that the use of a DNase in a detergent composition results in an enhanced effect of perfume compounds in the composition that allows for the amount of perfume to be reduced while still maintaining a freshness and cleanliness effect of the perfume on a textile washed with the detergent composition.
Summary of the Invention
The present invention relates to detergent compositions comprising an enzyme having DNase activity and at least one perfume compound, as well as to use of a polypeptide having DNase activity in detergent compositions comprising a perfume, e.g. for increasing binding of a perfume to a textile during a laundry process, for increasing perfume retention on a textile after wash, and/or for enhancing the effect of a perfume in a detergent composition.
The invention further relates to a method for increasing binding of a perfume to a textile during a laundry process, and/or for increasing perfume retention on a textile, the method comprising washing the textile with a detergent composition comprising at least one perfume compound and a polypeptide having DNase activity.
The invention further relates to a method for enhancing the effect of a perfume in a laundry detergent composition, and/or for preparing a detergent composition with a reduced perfume content while maintaining perfume effect after wash, the method comprising preparing a detergent composition comprising at least one perfume compound and a polypeptide having DNase activity.
The invention further relates to a method for cleaning an item, wherein the item is preferably a textile, comprising the steps of: a) contacting the item with a detergent composition comprising a polypeptide having DNase activity and at least one perfume compound, and optionally b) rinsing the item.

Definitions
As used herein, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
If not indicated otherwise, all references to percentages in relation to the disclosed compositions relate to wt.% relative to the total weight of the respective composition.
DNase (deoxyribonuclease): The term “DNase” means a polypeptide or an enzyme with DNase activity that catalyzes the hydrolytic cleavage of phosphodiester linkages in the DNA backbone, thus degrading DNA. For purposes of the present invention, DNase activity is determined according to the procedure described in Assay 1 or Assay 2 herein. Biofilm: A “biofilm” is organic matter produced by any group of microorganisms in which cells stick to each other or stick to a surface, such as a textile, dishware or hard surface or another kind of surface. These adherent cells are frequently embedded within a self-produced matrix of extracellular polymeric substance (EPS). Biofilm EPS is a polymeric conglomeration generally composed of extracellular DNA, proteins, and polysaccharides. Biofilms may form on living or non-living surfaces. The microbial cells growing in a biofilm are physiologically distinct from planktonic cells of the same organism, which, by contrast, are single-cells that may float or swim in a liquid medium. Bacteria living in a biofilm usually have significantly different properties from planktonic bacteria of the same species, as the dense and protected environment of the film allows them to cooperate and interact in various ways. One benefit of this environment for the microorganisms is increased resistance to detergents and antibiotics, as the dense extracellular matrix and the outer layer of cells protect the interior of the community. The biofilm living bacteria do not lose their ability to live as planktonic cells if the biofilm matrix is compromised. On laundry, biofilm- or EPS-producing bacteria can e.g. be found among the following species: Acinetobacter sp., Aeromicrobium sp., Brevundimonas sp., Microbacterium sp., Micrococcus luteus, Pseudomonas sp., Staphylococcus epidermidis and Stenotrophomonas sp.

Detergent composition: The term “detergent composition” or “cleaning composition” refers to compositions that find use in the removal of undesired compounds from items to be cleaned, such as textiles. The detergent composition may be used to e.g. clean textiles for both household cleaning and industrial cleaning. The term encompasses any materials/compounds selected for the particular type of detergent composition desired and the form of the product (e.g., liquid, gel, powder, granulate, paste, or spray compositions) and includes, but is not limited to, detergent compositions such as liquid and/or solid laundry detergents and fine fabric detergents; fabric fresheners; fabric softeners; and textile and laundry pre-spotters/pretreatment. In addition to containing the enzyme of the invention, the detergent formulation may contain one or more additional enzymes (such as proteases, amylases, lipases, cutinases, cellulases, endoglucanases, xyloglucanases, pectinases, pectin lyases, xanthanases, peroxidases, haloperoxygenases, catalases, mannanases, nucleases or any mixture thereof), and/or detergent adjunct ingredients such as surfactants, builders, chelators or chelating agents, bleach system or bleach components, polymers, fabric conditioners, foam boosters, suds suppressors, dyes, perfume, tannish inhibitors, optical brighteners, bactericides, fungicides, soil suspending agents, anti-corrosion agents, enzyme inhibitors or stabilizers, enzyme activators, transferases, hydrolytic enzymes, oxido reductases, bluing agents and fluorescent dyes, antioxidants, and solubilizers. In one preferred embodiment, the detergent composition is a laundry detergent composition. In another preferred embodiment, the detergent composition is a fabric softener.
Detergent enzyme: The term “detergent enzyme” as used herein refers to enzymes that are not encompassed by the term “DNase” as defined herein. The term “detergent enzyme” includes enzymes traditionally used in detergent compositions, including but not limited to proteases, amylases, lipases, mannanases, pectate lyases and cellulases. Other detergent enzymes may e.g. include carbohydrases, pectinases, arabinases, galactanases, xylanases, oxidases or peroxidases.
Expression: The term “expression” includes any step involved in the production of a polypeptide including, but not limited to, transcription, post-transcriptional modification, translation, post-translational modification, and secretion.
Fragment: The term “fragment” means a polypeptide having one or more amino acids absent from the amino and/or carboxyl terminus of a mature polypeptide or domain , where the fragment has DNase activity.
Host cell: The term "host cell" means any cell type that is susceptible to transformation, transfection, transduction, or the like with a nucleic acid construct or expression vector comprising a polynucleotide of the present invention. The term “host cell” encompasses any progeny of a parent cell that is not identical to the parent cell due to mutations that occur during replication.
Isolated: The term “isolated” means a polypeptide, nucleic acid, cell, or other specified material or component that is separated from at least one other component with which it is naturally associated, including but not limited to, for example, other proteins, nucleic acids, cells, etc. An isolated polypeptide, nucleic acid, cell or other material is thus in a form that does not occur in nature.
Laundering: The term “laundering” relates to both household laundering and industrial laundering and means the process of treating textiles with a solution containing a cleaning or detergent composition of the present invention. The laundering process can for example be carried out using e.g. a household or an industrial washing machine or can be carried out by hand . A “laundry process” is intended to include any steps related to laundry, whether by hand or by machine, including but not limited to pre-treatment of fabrics, washing steps using a solution containing a laundry detergent composition, and rinsing steps e.g. using a fabric softener.
Malodor: The term ’’malodor” means an odor which is not desired on clean items. One example of malodor is compounds with an unpleasant smell, which may be produced by microorganisms. Another example is unpleasant smells which can be sweat or body odor adhered to an item which has been in contact with human or animal. Another example of malodor can be the odor from spices which stick to items, for example curry or other spices which smell strongly.
Mature polypeptide: The term “mature polypeptide” means a polypeptide in its mature form following N-terminal processing (e.g., removal of signal peptide). It is known in the art that a host cell may produce a mixture of two of more different mature polypeptides (i.e., with a different C- terminal and/or N-terminal amino acid) expressed by the same polynucleotide. It is also known that different host cells process polypeptides differently, and thus, one host cell expressing a polynucleotide may produce a different mature polypeptide (e.g., having a different C-terminal and/or N-terminal amino acid) as compared to another host cell expressing the same polynucleotide. Mature polypeptides of the invention may therefore have slight differences at the N- and/or C-terminal due to such differentiated expression by the host cell, while still having the same enzyme activity. A mature polypeptide having one or more amino acids absent from the N- and/or C-terminal may be considered to be a “fragment” of the full-length polypeptide. Similarly, a mature polypeptide having one or more additional amino acids at the N- and/or C-terminal due to differentiated expression may be considered to be an “extended” polypeptide.
Perfume effect: The term “perfume effect” in the context of the present invention is related to the human perception of perfume on washed clothes. The perfume effect of a polypeptide of the invention having DNase activity can be analyzed e.g. by means of a sensory evaluation such as that described in Example 1 . The perfume effect can alternatively be measured by GC-MS analysis and expressed quantitatively as a “fragrance intensity” e.g. as described in Examples 2 and 3. An increased perfume effect can thus be expressed as an increased fragrance intensity, such that washing an item with a DNase polypeptide according to the invention results in an increase in fragrance intensity compared to washing the item under the same conditions but without the DNase polypeptide.
Sequence identity: The relatedness between two amino acid sequences or between two nucleotide sequences is described by the parameter “sequence identity”. For purposes of the present invention, the sequence identity between two amino acid sequences is determined using the Needleman-Wunsch algorithm (Needleman and Wunsch, 1970, J. Mol. Biol. 48: 443-453) as implemented in the Needle program of the EMBOSS package (EMBOSS: The European Molecular Biology Open Software Suite, Rice etal., 2000, Trends Genet. 16: 276-277), preferably version 5.0.0 or later. The parameters used are gap open penalty of 10, gap extension penalty of 0.5, and the EBLOSUM62 (EMBOSS version of BLOSUM62) substitution matrix. The output of Needle labeled “longest identity” (obtained using the -nobrief option) is used as the percent identity and is calculated as follows:
(Identical Residues x 100)/(Length of Alignment - Total Number of Gaps in Alignment)
Textile: The term “textile” means any textile material including yarns, yarn intermediates, fibers, non-woven materials, natural materials, synthetic materials, and any other textile material, fabrics made of these materials and products made from fabrics (e.g., garments and other articles), and is intended to include the term “fabric” as well. The textile or fabric may be in the form of knits, wovens, denims, non-wovens, felts, yarns, and towelling. The textile may be cellulose based such as natural cellulosics, including cotton, flax/linen, jute, ramie, sisal or coir or manmade cellulosics (e.g. originating from wood pulp) including viscose/rayon, cellulose acetate fibers (tricell), lyocell or blends thereof. The textile or fabric may also be non -cellulose based such as natural polyamides including wool, camel, cashmere, mohair, rabbit and silk or synthetic polymers such as nylon, aramid, polyester, acrylic, polypropylene and spandex/elastane, or blends thereof as well as blends of cellulose based and non -cellulose based fibers. Examples of blends are blends of cotton and/or rayon/viscose with one or more companion material such as wool, synthetic fiber (e.g. polyamide fiber, acrylic fiber, polyester fiber, polyvinyl chloride fiber, polyurethane fiber, polyurea fiber, aramid fiber), and/or cellulose-containing fiber (e.g. rayon/viscose, ramie, flax/linen, jute, cellulose acetate fiber, lyocell). Fabric may be conventional washable laundry, for example stained household laundry. When the term fabric or garment is used it is intended to include the broader term textiles as well.
Variant: The term “variant” means a polypeptide having DNase activity comprising an alteration, i.e., a substitution, insertion, and/or deletion, at one or more positions. A substitution means replacement of the amino acid occupying a position with a different amino acid; a deletion means removal of the amino acid occupying a position; and an insertion means adding an amino acid adjacent to and immediately following the amino acid occupying a position.
Wash cycle: The term “wash cycle” is defined herein as a washing operation wherein textiles are immersed in a wash liquor, mechanical action of some kind is applied to the textile in order to release stains and to facilitate flow of wash liquor in and out of the textile, and finally the superfluous wash liquor is removed. After one or more wash cycles, the textile is generally rinsed and dried.
Wash liquor: The term “wash liquor” is intended to mean the solution or mixture of water and detergents, in particular a detergent composition of the invention, used for laundering textiles, or for hard surface cleaning or dishwashing. The term is also intended to include e.g. rinse solutions comprising a fabric softener comprising a DNase polypeptide used for rinsing textiles.
Nomenclature
For purposes of the present invention, the nomenclature [E/Q] or [EQ] means that the amino acid at this position may be a glutamic acid (Glu, E) or a glutamine (Gin, Q). Likewise, the nomenclature [V/G/A/l] or [VGAI] means that the amino acid at this position may be a valine (Vai, V), glycine (Gly, G), alanine (Ala, A) or isoleucine (lie, I), and so forth for other combinations as described herein. Unless otherwise limited further, the amino acid X is defined such that it may be any of the 20 natural amino acids.
Substitutions are typically indicated with the original amino acid, the position number, and the replacement amino acid. For example, A226V indicates that the original alanine residue in position 226 has been replaced by a valine residue.
Deletions are indicated with an asterisk (*). For example, G184* indicates that the original glycine residue in position 184 has been deleted.
Insertions are indicated by listing the original amino acid, the position number, the original amino acid and the inserted amino acid. For example, S97SD indicates that an aspartic acid residue has been inserted after the serine residue in position 97.
Detailed Description of the Invention
The inventors have surprisingly found that enzymes having DNase activity act synergistically with volatile perfume compounds, resulting in an enhanced binding of perfume compounds to textiles washed with a detergent composition comprise a DNase and one or more perfume compounds. As a result of the increased retention of perfume compounds by the textiles, an enhanced perfume effect is obtained, allowing the amount of perfume in such detergent compositions to be reduced while still maintaining the desired perfume effect.
Volatile perfume compounds are often added to detergent compositions, e.g. laundry detergents or fabric softeners, to mask malodors and to provide a fresh and clean scent in the washed items, e.g. textiles. These malodors may come from various sources. One example is buildup of organic matter such as sebum, body soils, cell debris, biofilm, EPS etc. It has previously been shown that polypeptides having DNase activity can be used for preventing or removing biofilm on items such as textiles or fabric; see e.g. WO 2015/155350, WO 2017/060475 and Morales-Garcia et al, J Surfact Deterg (2020) DOI 10.1002/jsde.12398. Polypeptides having DNase activity have also been shown to be able to reduce malodor in washed textiles. However, there is no suggestion in the art that there might actually be a synergistic effect between polypeptides having DNase activity and perfume compounds present in detergent compositions. While perfumes and the associated fresh and clean scent are often desired by consumers in detergent compositions such as laundry detergents, there are as noted above disadvantages to the use of perfumes, including the high cost of perfume compounds as well as the risk of allergy.
The present invention addresses these challenges by providing detergent compositions comprising polypeptides with DNase activity that have been found to have synergistic effects with perfume compounds, and which can thereby reduce the need for perfume addition to detergent compositions, in particular laundry detergent compositions.
Thus, one embodiment of the invention relates to a detergent composition comprising a polypeptide having DNase activity and at least one perfume compound, where the amount of perfume is reduced compared to a comparable detergent composition without a DNase. It will be understood that such compositions will have a perfume effect corresponding to that of a comparable detergent composition without the DNase and with a greater amount of perfume. This may allow the amount of perfume to be reduced to e.g. no more than 90%, such as no more than 80% or even lower, e.g. no more than 70% or no more than 60%, relative to the comparable composition without a DNase, with substantially the same perfume effect. This may be assessed e.g. using a sensory evaluation such as that described in Example 1 or quantitatively by GC-MS analysis e.g. as described in Example 2.
The invention thus provides a detergent composition comprising a DNase and at least one perfume compound, wherein the composition has an increased perfume effect relative to a comparable detergent composition without a DNase.
In a preferred embodiment, the detergent composition is a laundry detergent composition, wherein the composition provides an increased perfume retention on a textile.
In this embodiment, the invention thus provides a laundry detergent composition comprising a DNase and at least one perfume compound, wherein the composition has increased perfume retention on a textile after wash relative to a comparable detergent composition without a DNase.
In another preferred embodiment, the detergent composition is a fabric softener composition, wherein the composition provides an increased perfume retention on a textile.
In this embodiment, the invention thus provides a fabric softener composition comprising a DNase and at least one perfume compound, wherein the composition has increased perfume retention on a textile after rinse relative to a comparable fabric softener composition without a DNase. In another embodiment, the detergent composition may be for cleaning of hard surfaces, for example for dishwashing, or for cleaning hard surfaces such as those found in kitchens and bathrooms.
Enzyme having DNase activity (DNase)
The DNase in the detergent compositions, uses and methods of the present invention is a nuclease polypeptide having DNase activity that catalyzes the hydrolytic cleavage of phosphodiester linkages in a DNA backbone, thus degrading DNA. The terms “DNase” and “polypeptide with/having DNase activity” may be used interchangeably herein.
Preferably, the DNase is selected from any of the enzyme classes E.C. 3.1.21 .X, where X = 1 , 2, 3, 4, 5, 6, 7, 8 or 9, e.g. Deoxyribonuclease I, Deoxyribonuclease IV, Type I site-specific deoxyribonuclease, Type II site-specific deoxyribonuclease, Type III site-specific deoxyribonuclease, CC-preferring endo-deoxyribonuclease, Deoxyribonuclease V, T(4) deoxyribonuclease II, T(4) deoxyribonuclease IV or E.C. 3.1.22.Y where Y = 1 , 2, 4 or 5, e.g. Deoxyribonuclease II, Aspergillus deoxyribonuclease K(1 ), Crossover junction endo- deoxyribonuclease, or Deoxyribonuclease X.
Preferably, the DNase activity is obtained from a microorganism, and the DNase is a microbial enzyme. The DNase is more preferably of fungal or bacterial origin.
The polypeptide having DNase activity may for example be a fungal DNase obtained from Aspergillus, for example from Aspergillus oryzae.
Suitable bacterial DNases may, for example, be obtained from species of Bacillus and related genera (cf. Patel and Gupta, Int. J. Syst. Evol. Microbiol. 2020; 70:406-438, who proposed six new Bacillaceae genera from species formerly classified as belonging to the genus Bacillus), e.g. from Bacillus, Cytobacillus, Metabacillus, Alkalihalobacillus, Rossellomorea or Mesobacillus. Examples of species from which DNases may be obtained include Bacillus licheniformis, Bacillus subtilis, Bacillus horikoshii, Cytobacillus horneckiae, Metabacillus indicus, Alkalihalobacillus algicola, Rossellomorea vietnamensis, Alkalihalobacillus hwajinpoensis, Metabacillus indicus, Mesobacillus campisalis, Bacillus idriensis, Bacillus algicola, Bacillus marisflavi and Bacillus luciferensis. Preferred bacterial DNases include those obtained from Metabacillus indicus (previously known as Bacillus cibi) and variants thereof.
The DNase may also be obtained from any of the following: Pyrenochaetopsis sp., Vibrissea flavovirens, Setosphaeria rostrate, Endophragmiella valdina, Corynespora cassiicola, Paraphoma sp., Mon i Unia fructicola, Curvularia lunata, Penicillium reticulisporum, Penicillium quercetorum, Setophaeosphaeria sp., Alternaria, Alternaria sp., Trichoderma reesei, Chaetomium thermophilum, Scytalidium thermophilum, Metapochonia suchlasporia, Daldinia fissa, Acremonium sp., Acremonium dichromosporum, Sarocladium sp., Metarhizium sp.

In some embodiments, the polypeptides having DNase activity are polypeptides comprising the PFAM domain DUF1524 ((pfam.xfam.org/), “The Pfam protein families database: towards a more sustainable future”, R.D. Finn, et.al. Nucleic Acids Research (2016) Database Issue 44:D279-D285”). The DUF1524 domain contains a conserved HXXP sequence (where H is the amino acid histidine, P is the amino acid proline, and X is any amino acid motif) commonly found in nucleases (M.A. Machnicka, et al. Phylogenomics and sequence-structure-function relationships in the GmrSD family of Type IV restriction enzymes, BMC Bioinformatics, 2015, 16, 336). DUF stands for domain of unknown function, and polypeptide families comprising, e.g., DUF have been collected in the Pfam database, which provides sequence alignments and hidden Markov models that define the collected protein domains.
Thus, in some embodiments the polypeptides having DNase activity in the composition of the invention comprise the DUF1524 domain. For further information on DNases comprising the DUF1524 domain, see WO 2017/060475, which is hereby incorporated by reference.
In some embodiments, the DNase is a NUC1 or NUC1_A DNase. A NUC1 DNase is a DNase comprising a domain termed NUC1 , and polypeptides with this domain are in addition to having DNase activity characterized by comprising certain motifs. Similarly, a NUC1 sub-domain had been identified, termed the NUC1_A domain, which also is characterized by comprising certain motifs. The NUC1 and NUC1_A DNases are described in WO 2017/060475 and WO 2018/184873, which are hereby incorporated by reference.
The preparation of the polypeptide having DNase activity as described herein can e.g. be performed as described in WO 2017/059802 (incorporated herein by reference), in particular in the sections Nucleic Acid Construct, Expression Vectors, Host Cells, Methods of Production and Fermentation Broth Formulations. See also WO 2015/155350, WO 2017/060475, WO 2017/060505, WO 2017/064269 and WO 2018/177936, the contents of which are incorporated herein by reference.
In one embodiment, the polypeptide having DNase activity is a polypeptide having at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95% or 100% sequence identity to the polypeptide of SEQ ID NO: 1 , or a fragment thereof having DNase activity.
It is known in the art that a host cell may produce a mixture of two of more different mature polypeptides (i.e., with a different C-terminal and/or N-terminal amino acid) expressed by the same polynucleotide. It is also known that different host cells process polypeptides differently, and thus, one host cell expressing a polynucleotide may produce a different mature polypeptide (e.g., having a different C-terminal and/or N-terminal amino acid) as compared to another host cell expressing the same polynucleotide.
In the context of the polypeptide having SEQ ID NO: 1 , the N-terminal amino acid portion, e.g. the 15 or 17 N-terminal amino acid residues, may be a propeptide sequence. Thus, in one embodiment, the mature polypeptide is a fragment of SEQ ID NO: 1 comprising 206 amino acid residues, corresponding to amino acids 16 to 221 of SEQ ID NO: 1 (shown as SEQ ID NO: 2). In a similar embodiment, the mature polypeptide is a fragment of SEQ ID NO: 1 comprising 204 amino acid residues, corresponding to amino acids 18 to 221 of SEQ ID NO: 1 (shown as SEQ ID NO: 3). The polypeptide having DNase activity may thus be a polypeptide having at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95% or 100% sequence identity to the mature polypeptide of SEQ ID NO: 2 or SEQ ID NO: 3.
A polypeptide having DNase activity and at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95% or 100% sequence identity to the polypeptide of SEQ ID NO: 1 , or a fragment thereof having DNase activity, e.g. a polypeptide having at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95% or 100% sequence identity to the polypeptide of SEQ ID NO: 2 or SEQ ID NO: 3, may be a variant having one or more alterations, e.g. substitutions, compared to SEQ ID NO: 1 . Polypeptide variants may be engineered using protein engineering methods known in the art to produce a polypeptide having one or more improved properties compared to the parent polypeptide, for example improved detergent stability and/or wash performance, e.g. an improved deep cleaning effect.
A variant of the polypeptide of SEQ ID NO: 1 , SEQ ID NO: 2 or SEQ ID NO: 3 may, for example, include any of the alterations disclosed in WO 2017/064269 (incorporated herein by reference). In some embodiments, the polypeptide may thus be a variant of SEQ ID NO: 1 , SEQ ID NO: 2 or SEQ ID NO: 3 having DNase activity and comprising a substitution at one or more positions corresponding to positions 4, 17, 19, 36, 38, 39, 40, 41 , 45, 51 , 53, 54, 55, 57, 64, 66, 67, 68, 69, 70, 71 , 72, 74, 75, 77, 82, 83, 84, 85, 86, 88, 91 , 99, 101 , 105, 106, 115, 1 16, 135, 136, 138, 139, 140, 141 , 151 , 152, 153, 154, 162, 163, 164, 166, 168, 169, 173, 182, 183, 184, 185, 186, 189, 212 and 215 of SEQ ID NO: 1 , wherein the variant has a sequence identity to the polypeptide shown in SEQ ID NO: 1 , SEQ ID NO: 2 or SEQ ID NO: 3 of at least 80%, e.g. at least 85%, at least 90%, at least 95%, at least 96%, at least 97%, at least 98% or at least 99%.

In one aspect, the polypeptide having DNase activity belongs to the GYS-clade and comprises one or both of the motifs [D/M/L][S/T]GYSR[D/N] (SEQ ID NO: 4) and/or ASXNRSKG (SEQ ID NO: 5).
In one embodiment of this aspect, the polypeptide having DNase activity is a polypeptide comprising one or both of the motifs [D/M/L][S/T]GYSR[D/N] (SEQ ID NO: 4) and/or ASXNRSKG (SEQ ID NO: 5) and having at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95% or 100% sequence identity to the polypeptide of SEQ ID NO: 6, or a fragment thereof having DNase activity. In this embodiment, the polypeptide having DNase activity may be a variant having one or more alterations, e.g. substitutions, compared to SEQ ID NO: 6.

Perfumes
The term “perfume compound” refers to a volatile fragrance compound that is suitable for use in a perfume. A “perfume compound” may also be referred to by similar terms such as a “perfume component” or a “fragrance compound”.
The term "perfume" includes perfume raw materials and compositions, scents and oils, e.g. essential oils. A wide variety of chemicals are known for fragrance (i.e., perfume) uses, including compounds such as aldehydes, ketones and esters. Also naturally occurring plant and animal oils and exudates comprising complex mixtures of various chemical components are known for use as fragrances.
A perfume is a blend of volatile compounds with different volatilities which can bind to receptors in the nose and therefore has a smell or odor, usually a pleasant one. These compounds are also known as odorants or fragrances. Most perfumes possess molar weights of up to approximately 200 g/mol, in some cases up to about 300 g/mol. Larger molecules are not volatile enough to be perceived by the human nose.
The volatility of a compound describes how readily it vaporizes by way of evaporation or boiling. Perfume compounds vaporize, depending on their volatility, by evaporation at room temperature and atmospheric pressure. Volatility is often described using vapor pressure or boiling point, with a high vapor pressure or low boiling point indicating a high volatility. Although the volatility of a compound is related to its molecular weight, other factors such as structure and polarity also play a role, as does interaction between fragrance compounds.
The most volatile fragrance compounds are referred to as top notes or head notes, whereas increasingly less volatile compounds are referred to as heart notes or middle notes, and the least volatile as base notes or back notes. The top notes are responsible for the first impression of a detergent, and the heart notes represent the characteristic smell. The base notes ensure the more substantial, long-lasting effect of the perfume.
The top, heart (middle) and base notes may be grouped based in different criteria. One such grouping is that of Poucher (Poucher, W. A. (1993). Poucher's Perfumes, Cosmetics and Soaps, Vol. 2 (Ninth ed.), Chapman & Hall, page 55). Poucher classified fragrance compounds according to an evaporation coefficient, with top notes having a coefficient of from 1 to 14, middle notes having a coefficient of from 15 to 60, and base notes having a coefficient of from 61 to 100.
Fragrance manufacturers and sellers provide information about their fragrance compounds such as molecular weight, vapor pressure and boiling point, and may also indicate whether individual fragrance compounds are top notes, middle notes or base notes. Such information is e.g. provided at iff.com/portfolio/products/fragrance-ingredients/online- compendium and at shop.perfumersapprentice.com.
For purposes of the present invention, top, heart and base notes may also be defined based on retention time (in minutes) in GC-MS performed using the parameters as defined in Example 2 herein. Using this definition, top notes are defined as fragrance compounds that have a retention time in GC-MS of less than 8.76 min, heart notes are defined as fragrance compounds that have a retention time in GC-MS in the range of from 8.76 to 16.51 min, and base notes are defined as fragrance compounds that have a retention time in GC-MS of more than 16.51 min.
In one embodiment of the invention, the presence of a polypeptide having DNase activity in a detergent composition, e.g. a laundry detergent composition or a fabric softener, results in an increase in binding and/or retention of top note and/or heart note perfume compounds compared to base note compounds, and thus an increased relative perfume effect for these notes. In one particular embodiment, at least the heart note compounds are increased relative to the base note compounds. In another particular embodiment, the top note and heart note compounds are increased relative to the base note compounds. In a further particular embodiment, at least the top note compounds are increased relative to the base note compounds.
In an embodiment, the presence of a polypeptide having DNase activity in a detergent composition, e.g. a laundry detergent composition or a fabric softener, results in an increase in binding and/or retention of top note and/or heart note perfume compounds compared to base note compounds when measured on a polyester material.
It should be noted that in the context of the invention, the precise classification of any given fragrance compound as being a top, heart or base note is not important. Rather, as it will be apparent from the explanation above, it is a question of how a DNase polypeptide in a detergent composition effects the overall binding and/or retention of the different groups of fragrance compounds, where such compounds are broadly classified into the three categories of top, heart and base notes.
Besides volatility, the odor detection threshold of the fragrance compounds is also important for the perfume functions. The odor detection threshold value is defined as the minimal concentration of a substance that can be detected by a human nose. Thus, compounds with a lower detection odor threshold are more easily detected by humans. Although the threshold is subjective and may vary, it mainly depends on three factors, the vapor pressure, water solubility and the water/organic solvent (octanol) partition coefficient, which together account for 77% of variance in threshold values (Rodriguez et aL, 2011 , Flavour and Fragrance Journal 26: 421 -428).
Just like fragrances, malodors are also volatile compounds that can bind to receptors in the nose. However, in contrast to fragrances used in perfume, malodors are perceived as unpleasant. A perfume can interfere with the perception of malodors by competing with the receptors in the nose, thereby masking the malodors. In another words, fragrances do not interact with malodors, and malodors are not physically removed or chemically eliminated. Rather, perfume compositions are carefully designed to mask the anticipated malodors.
The duration of the “freshness” or “cleanliness” effect provided by a perfume in a detergent composition is influenced by how fragrances and malodors are retained on the washed fabric. Laundry malodors can come from various sources, including human body odor as well as malodors from the environment such as kitchen odors, cigarettes, food stains, etc. Another important source of malodors is from microbes present in the textile, which can metabolize the substances transferred from the human body (sweat, dead cells, sebum, etc.) and generate malodors during drying, storage or wearing (Bockmuehl et aL, 2019, Microbial Cell 6: 299-306).
Fiber type also plays an important role in retaining and release of odor compounds, e.g. malodor compounds may be more effectively removed from cotton than from polyester. This is partly related to the polarity (hydrophilicity) of the odor compounds and that of the textile fibers, with cotton containing mainly highly polar cellulosic fibers, while fibers of polyester and wool are relatively non-polar compared to cotton fibers. In general, the order of compound polarity of perfume compounds from high to low is as follows: Amide > Acid > Alcohol > Ketone ~ Aldehyde > Ester > Alkane.
When some typical laundry malodor compounds were added to cotton or polyester, they were effectively removed from cotton, while they strongly adhered to the more hydrophobic polyester after wash. The strong association of odorants with the polyester fibers during wash was found to contribute to a more complex odor profile in polyester than in cotton (Munk et aL, 2001 , Journal of Surfactants and Detergents 4: 385-394).
In addition, “invisible dirt” present on the textile also affects odor retention. Used textiles often contain human secretion (e.g. sebum, keratin) and microbial soil (e.g. biofilm, DNA, carbohydrates), which may not be visible but which contribute to binding of odor compounds on the textile.
Perfume compounds used in laundry detergents may be chemical compounds from any of several different classes or essential oils or other natural compounds. The perfumes that may be used in the context of the present invention are not subject to any restrictions. Thus, in particular synthetic or natural odorant substance compounds of the types esters, ethers, aldehydes (fragrance aldehydes, odorant aldehydes), ketones (fragrance ketones, odorant ketones), alcohols, hydrocarbons, acids, carbonic acid esters, aromatic hydrocarbons, aliphatic hydrocarbons, saturated and/or unsaturated hydrocarbons and mixtures of these may be used as perfume compounds.
Individual perfume compounds, e.g. synthetic products of the ester, ether, aldehyde, ketone, alcohol, and hydrocarbon types, can be used as well as mixtures thereof. It is preferred, however, to use mixtures of different perfume compounds, which together generate an attractive scent note. Such mixtures can also contain natural perfume mixtures such as those accessible from plant sources, e.g. pine, citrus, jasmine, patchouli, rose or ylang-ylang oil.

The choice of cleaning components may include, for textile care, the consideration of the type of textile to be cleaned, the type and/or degree of soiling, the temperature at which cleaning is to take place, and the formulation of the detergent product. Although components mentioned below are categorized by general header according to a particular functionality, this is not to be construed as a limitation, as a component may comprise additional functionalities as will be appreciated by the skilled artisan.
Surfactants
The cleaning composition may comprise one or more surfactants, which may be anionic and/or cationic and/or non-ionic and/or semi-polar and/or zwitterionic, or a mixture thereof. In a particular embodiment, the detergent composition includes a mixture of one or more nonionic surfactants and one or more anionic surfactants. The surfactant is typically present at a level of from about 1 % to 70% by weight, such as about 1 wt% to about 40 wt%, or about 3 wt% to about 20 wt%, or about 3 wt% to about 10 wt%.

Proteases
Suitable proteases may be of any origin, but are preferably of bacterial or fungal origin, optionally in the form of protein engineered or chemically modified mutants. The protease may be an alkaline protease, such as a serine protease or a metalloprotease. A serine protease may for example be of the S1 family, such as trypsin, or the S8 family such as a subtilisin. A metalloprotease may for example be a thermolysin, e.g. from the M4 family, or another metalloprotease such as those from the M5, M7 or M35 families.
The term "subtilases" refers to a sub-group of serine proteases according to Siezen et aL, Protein Eng. 4 (1991 ) 719-737 and Siezen et aL, Protein Sci. 6 (1997) 501 -523. Serine proteases are a subgroup of proteases characterized by having a serine in the active site, which forms a covalent adduct with the substrate. The subtilases may be divided into six subdivisions, the Subtilisin family, the Thermitase family, the Proteinase K family, the Lantibiotic peptidase family, the Kexin family and the Pyrolysin family.
Although proteases suitable for detergent use may be obtained from a variety of organisms, including fungi such as Aspergillus, detergent proteases have generally been obtained from bacteria and in particular from Bacillus. Examples of Bacillus species from which subtilases have been derived include Bacillus lentus, Bacillus alkalophilus, Bacillus subtilis, Bacillus amyloliquefaciens, Bacillus licheniformis, Bacillus pumilus and Bacillus gibsonii. Particular subtilisins include subtilisin lentus, subtilisin Novo, subtilisin Carlsberg, subtilisin BPN’, subtilisin 309, subtilisin 147 and subtilisin 168 and e.g. protease PD138 (described in WO 93/18140). Other useful proteases are e.g. those described in WO 01/16285 and WO 02/16547.

Formulation of detergent products
The cleaning composition of the present invention may be formulated, for example, as a hand or machine laundry detergent composition including a laundry additive composition suitable for pretreatment of stained fabrics and a rinse added fabric softener composition, or be formulated as a detergent composition for use in general household hard surface cleaning operations, or be formulated for hand or machine dishwashing operations. In a specific aspect, the present invention provides a detergent additive comprising one or more enzymes as described herein. The cleaning composition of the invention may be in any convenient form, e.g., a bar, a homogenous tablet, a tablet having two or more layers, a pouch having one or more compartments, a regular or compact powder, a granule, a paste, a gel, or a regular, compact or concentrated liquid.
Pouches can be configured as single or multicompartments. It can be of any form, shape and material which is suitable for hold the composition, e.g. without allowing the release of the composition to release of the composition from the pouch prior to water contact. The pouch is made from water soluble film which encloses an inner volume. Said inner volume can be divided into compartments of the pouch. Preferred films are polymeric materials preferably polymers which are formed into a film or sheet. Preferred polymers, copolymers or derivates thereof are selected polyacrylates, and water-soluble acrylate copolymers, methyl cellulose, carboxy methyl cellulose, sodium dextrin, ethyl cellulose, hydroxyethyl cellulose, hydroxypropyl methyl cellulose, malto dextrin, poly methacrylates, most preferably polyvinyl alcohol copolymers and, hydroxypropyl methyl cellulose (HPMC). Preferably the level of polymer in the film for example PVA is at least about 60%. Preferred average molecular weight will typically be about 20,000 to about 150,000. Films can also be of blended compositions comprising hydrolytically degradable and water-soluble polymer blends such as polylactide and polyvinyl alcohol (known under the Trade reference M8630 as sold by MonoSol LLC, Indiana, USA) plus plasticisers like glycerol, ethylene glycerol, propylene glycol, sorbitol and mixtures thereof. The pouches can comprise a solid laundry cleaning composition or part components and/or a liquid cleaning composition or part components separated by the water- soluble film. The compartment for liquid components can be different in composition than compartments containing solids: US2009/0011970 A1 .
Detergent ingredients can be separated physically from each other by compartments in water dissolvable pouches or in different layers of tablets. Thereby negative storage interaction between components can be avoided. Different dissolution profiles of each of the compartments can also give rise to delayed dissolution of selected components in the wash solution.
A liquid or gel detergent which is not unit dosed may be aqueous, typically containing at least 20% by weight and up to 95% water, such as up to about 70% water, up to about 65% water, up to about 55% water, up to about 45% water, up to about 35% water. Other types of liquids, including without limitation, alkanols, amines, diols, ethers and polyols may be included in an aqueous liquid or gel. An aqueous liquid or gel detergent may contain from 0-30% organic solvent. A liquid or gel detergent may also be non-aqueous.
Formulation of enzyme in granules
Non-dusting granulates may be produced e.g. as disclosed in US 4,106,991 and 4,661 ,452 and may optionally be coated by methods known in the art. Examples of waxy coating materials are polyethylene oxide) products (polyethyleneglycol, PEG) with mean molar weights of 1000 to 20000; ethoxylated nonylphenols having from 16 to 50 ethylene oxide units; ethoxylated fatty alcohols in which the alcohol contains from 12 to 20 carbon atoms and in which there are 15 to 80 ethylene oxide units; fatty alcohols; fatty acids; and mono-, di- and triglycerides of fatty acids.

Protected enzymes may be prepared according to the method disclosed in EP 238,216.
The compositions of the invention may be formulated as a granule, for example as a cogranule that combines one or more enzymes. Each enzyme will then be present in more granules, securing a more uniform distribution of enzymes in the detergent. This also reduces the physical segregation of different enzymes due to different particle sizes. Methods for producing multi-enzyme co-granulates for the detergent industry are disclosed in the IP.com disclosure IPCOM000200739D.
Another example of formulation of enzymes by the use of co-granulates is disclosed in WO 2013/188331 , which relates to a detergent composition comprising (a) a multi-enzyme co- granule; (b) less than 10 wt% zeolite (anhydrous basis); and (c) less than 10 wt% phosphate salt (anhydrous basis), wherein said enzyme co-granule comprises from 10 to 98 wt% moisture sink component and the composition additionally comprises from 20 to 80 wt% detergent moisture sink component.

Example 1 : Sensory evaluation of perfume retention after wash in a liquid detergent with DNase
The evaluation of this example included the following steps:
Step 1 . Preparation of test items
Step 2. Wash test in detergent with and without DNase
Step 3. Human panel evaluation of washed items
Subsequent to the sensory evaluation, GC-MS analysis of washed items was performed. This is described in Example 2.
1 . Preparation of test items
The test items were 100% polyester T-shirts weighing 130 g/m2. The T-shirts were preaged before being handed out to be used for exercise by test persons.
Pre-aging procedure: T-shirts weighing a total of 4 kg were added to a Wascator FOM 71 CLS washing machine from Electrolux together with 75 g of IEC* A detergent. The detergent was mixed with 50 g tap water plus 28 g of ballast soil with the following composition:
The above ingredients were mixed into a homogenous material by mixing melted lanolin and sebum (melted by heating at 50°C) with the mixed dry ingredients, followed by addition of glycerol and tryptone soy broth and stirring the mixture with a magnetic stirrer at 50°C for about two hours. The mixture was then cooled to room temperature and stored at 5°C.
The Wascator was programmed to wash for 12 hours without a final rinse. 75 g of new detergent IEC* A was then added, and a one-hour wash program with two rinses was performed, after which the T-shirts were tumble dried.
The T-shirts were then handed out for use by members of either a soccer team or a running team. They were worn for at least one hour of intensive training during two separate training sessions, drying the T-shirts in between. They were then returned to the laboratory and incubated in a safety cupboard for safety reasons for three days, after which they were moved to a climate chamber for a 24h incubation at 30°C and 95% relative humidity, followed by collecting all the T-shirts in a box with a lid and letting them incubate at 30°C for another 24h. All T-shirts were sorted by smell. Those without smell were discarded, while those with intense smell could be used as test material.
2. Wash test in detergent with and without DNase
Since left and right armpits can smell differently, cutouts from each were made using a 6x8 cm oval template. Cutout swatches from the left and right armpits of each T-shirt were cut into 4 pieces, resulting in a total of 8 pieces from each T-shirt. These were divided among 4 nylon stockings that were used as washing bags, such that pieces from the left and right armpit and from the front and back side of the armpit were divided into different stockings. Cutouts from 4 T- shirts were divided in this manner among 4 nylon stockings, i.e. each stocking contained a total of 8 pieces from 4 different T -shirts. The nylon stockings were sealed with a knot or a rubber band before wash and were discarded after wash.
The rest of the T-shirts were cut into two pieces each, with one half T-shirt being washed with DNase and the other half without DNase. The nylon stockings containing the armpit samples were washed together with the half T-shirts as well as ballast consisting of 1 kg of discarded household garments (each cut in two and divided equally between the two washing machines) and 1 .5 kg of clean ballast items in the form of 5 cotton T-shirts, 1 towel and 4-6 tea towels.
Three washes were performed in each round:
1 st wash: A clean T-shirt was washed using the same detergent as that used in the test. This functioned as a clean background sample to give a “pure fragrance impression”.
2nd wash: This was a blank test wash with detergent alone.
3rd wash: Test wash using detergent and DNase.
Washing was performed in a standard US top loader washing machine with the armpit samples, half T-shirts and ballast as described above, using the following wash program:
• Load Size: Medium
• Wash temp.: 30°C
• Extra Rinse: On
• Program: Normal, Regular
• Duration: approx. 55 min
The main wash cycle water volume was approx. 67 liters of water with a hardness of water 6e dH (2:1 :1 .5 Ca:Mg:NaHCO3). The detergent was Arm & Hammer Oxiclean (Church & Dwight, USA), added directly to the machine in a dose of 54.8 g/wash. For washes with DNase, the DNase of SEQ ID NO: 1 was added to the wash water at a concentration of 2 ppm. For the 1st wash with a clean T-shirt, a single T-shirt was washed in the same manner as the 2nd wash with detergent alone, but without ballast. All items were line dried overnight after wash.
3. Human panel evaluation of washed items
Swatches were transferred from the dried stockings to 60L Nalophan bags sealed at the bottom and filled with filtered air (swatches from one stocking per bag). Background samples from the 1 st wash were cut out with a similar weight as the test samples and added to 2 bags. The bags are then stored at 30°C for 2 hours, after which they are ready for the sensory evaluation.
The sensory evaluation was performed using a PureSniff III device from Olfasense GmbH, Germany. The device has three chambers for simultaneous evaluation. The first chamber contained the background sample, while the other two chambers contained the test samples washed with or without DNase in a blinded order.
Each test panel member senses (smells) first the background sample and then the two test samples. The test is rated as a simple preference test in which the test person chooses the sample that he/she prefers.
The test is repeated with the remaining 6 test samples from each wash, each time evaluating a sample washed without DNase and a sample washed with DNase in blinded order.
Each test was repeated 3 times using 8 T-shirts (2 subgroups of 4), i.e. testing a total of 24 T-shirts in 12 pools. Seven test persons participated in the evaluation, thus providing a total of 84 different individual evaluations. The results are provided in Table 1 below.
Table 1 . Sensory results for 3 wash tests in liquid detergent with and without DNase (SEQ ID NO: 1 )
The results in Table 1 show that overall, there was a clear preference among the panelists for the T-shirt samples that were washed using a DNase.
Example 2: Perfume retention on textile after wash in liquid detergent with a DNase
The T-shirt samples which were evaluated by the panelists as described in Example 1 were further used for GC-MS analysis. Headspace SPME-GC-MS analysis of fragrances from the commercial detergent on polyester T-shirts was performed using an Agilent 7890 gas chromatograph coupled to an Agilent 5977 mass spectrometry GC-MS system.

Polyester T-shirts were prepared in the same manner as described above in Example 1 . For this example, they were washed with a commercial powder detergent, Gut & Gunstig (McBride, Germany), in Ell front loader machines (Miele Novotronic, Model W 1935 WTL) using tap water from Bagsvaerd, Denmark with a water hardness of about 20°dH. The wash program, was Cotton, Short (1 h 49 min, 1600 rpm) with a wash temperature of 30°C. For washes with DNase, 2 ppm of the DNase (SEQ ID NO: 1 ) was added directly to the washing machine. After wash, all items were line dried overnight, and then stored refrigerated before analysis.
T-shirt armpit samples and remaining half T-shirts (weight 530g) prepared as described in Example 1 were washed together with 1400g of ballast consisting of 6 used half polyester T- shirts, 5 dirty half cotton pillowcases, 3 frotte wash cloths (20x20 cm), 3 half shirts (polyester), and 2 dirty half cotton T-shirts.
Three washes were performed as described in Example 1 , i.e. a blank wash with a clean T-shirt and detergent to provide a clean background sample, and washes with and without DNase. The sensory evaluation was performed as in Example 1 . The results of the sensory evaluation are provided in Table 3 below.
Table 3. Sensory results for 3 wash tests in powder detergent with and without DNase (SEQ ID NO: 1 )
Example 4: Perfume retention on textile after wash in powder detergent with a DNase
T-shirt samples that had been subjected to a sensory evaluated by test persons as described in Example 3 were further used for GC-MS analysis, which was performed as described in Example 2. The results are provided in Table 4 below. Table 4. Fragrance intensity on the polyester T-shirts washed with or without DNase in a powder detergent.
The sensory evaluation data provided above in Tables 1 and 3 demonstrates that test persons clearly preferred the fragrance of the polyester T-shirt samples that had been washed according to the invention with a detergent composition containing a DNase. This was the case for samples washed with both the liquid detergent under North American wash conditions and the powder detergent under European conditions.
Similarly, the GC-MS data in Tables 2 and 4 shows that that the fragrance intensity on polyester T-shirts was increased for a variety of different perfume compounds, and that this was the case using different detergents and different washing conditions, when the samples were washed according to the invention with a composition contained a DNase.
Example 5: Perfume retention on textile after rinse in fabric softeners containing a DNase
The evaluation of this example included the following steps:
Step 1 . Preparation of test items
Step 2. Rinse test in softeners with and without DNase
Step 3. GC-MS analysis of the rinsed items
Step 1 . Preparation of test items
Prewash
New polyester T-shirts as described above were first prewashed.
Prewash of textiles was done primarily to remove starch, carboxymethyl cellulose (CMC) and other additives from the textiles. Protease (Savinase® 16L, Novozymes A/S, Denmark), amylase (Stainzyme® 12L, Novozymes A/S) and cellulase (Celluclean® ST, Novozymes A/S) were added to the prewashes to remove these additives. The textiles were washed three times in 86.1 g/wash detergent W-ECE-2 (wfk Testgewebe GmbH, Germany) using water with 15°dH water hardness (3.00 mL of 0.713 mol/L CaCh, 1.50 mL of 0.357 mol/L MgCh and 0.3371 g of NaHCOs in 1 L deionized water) and containing the following enzymes:
Adding DNA to the swatches
The prewashed T-shirts were then cut into small round swatches with a diameter of 2 cm. To each swatch, 47 pl of 1% (w/v) deoxyribonucleic acid (DNA) solution was added at the center of the swatch. The DNA solution was made by dissolving 100 mg deoxyribonucleic acid sodium salt from salmon testes (Sigma Aldrich) in 10 ml MilliQ water in a 25 ml beaker with constant stirring for 1 h at room temperature.
The swatches containing the DNA solution were then dried overnight (16 h) at room temperature in a fume hood with constant air flow.
Step 2. Rinse test in softeners with and without DNase
Detergent
Model detergent A2 was used in the main wash of this experiment. A wash solution of liquid model detergent A2 was prepared by weighing out the detergent and dissolving in water with a hardness of 15°dH, with the model detergent A2 dosed at 3.33 g/L.
Model detergent A2 contains the following ingredients:
12% Sodium salt of linear alkylbenzene sulphonates (Na-LAS), 12% alcohol ethoxylate (AEG) Biosoft N25-7 (Nl), 4% alkyl ethoxysulfate / sodium laureth sulfate (AEOS/SLES), 2% MPG (monopropylene glycol), 3.1% ethanol, 2% triethanolamine (TEA), 3% palm kernel oil soap, 2% sodium hydroxide, 3.9% sodium citrate, 1.5% diethylenetriaminepenta(methylenephosphonic acid) (DTMPA) and 0.5% phenoxyethanol; remainder water (all percentages are w/w).
Softeners
Three representative commercial European fabric softeners were tested in this experiment: Dun-let Dream of Freshness (Colgate), Lenor Weichspuler Aprilfrisch (Procter & Gamble) and Bamseline Dugfrisk (Unilever). Lenor Weichspuler Aprilfrisch was purchased from amazon.de, and the other two softeners were purchased from a supermarket in Denmark.
Rinse solutions of the above three softeners were prepared by weighing out softeners and dissolving in water with 15°dH hardness. Dosing of the softeners was calculated according to the suggested dosage for each at standard conditions for a 4-5 kg wash load, which was 25 ml, 27 ml and 27 ml for Lenor Weichspuler Aprilfrisch, Dun-let Dream of Freshness and Bamseline Dugfrisk, respectively. Considering that the average volume of water used in one rinse step in a common Ell washing machine (machine size 3.5-5 kg laundry load) is 13.5 L, the dosing of each softener used in this experiment was 1.85 ml/L, 2.0 ml/L and 2.0 ml/L for Lenor Weichspuler Aprilfrisch, Dun-let Dream of Freshness and Bamseline Dugfrisk, respectively.
Main wash
The dried swatches from Step 1 were washed in a Mini Launder-O-Meter (MiniLOM) wash. The miniLOM assay is a small-scale version of the Launder-OMeter® (LOM). A miniLOM basically consists of closed test tubes being rotated in a heating cabinet for a given time and at a given temperature. Each test tube represents one small washing machine. It is mainly used in testing of detergents and enzymes at European wash conditions.
In this experiment, three swatches were placed in a 50-ml glass tube and 20 ml of wash solution (15° dH water with 3.15 g/L Model A2). To better mimic the wash performance of commercial detergents in Europe, an enzyme blend, Medley® Brilliant (Novozymes A/S, Denmark), was added to all glass tubes at a dosage of 2.5% of the detergent. The enzyme blend contains a variety of commonly used enzymes, including protease, amylase, lipase, mannanase, pectate lyase and two cellulases.
The glass tubes were then mounted in a Mini-Launder-O-Meter (a Stuart Tube Rotator SB3) and rotated at 30°C for 60 minutes at 30 rpm.
First rinse
After the main wash, the rotator was placed at room temperature, and the wash liquor was carefully poured out of each tube. 30 ml of hard water (15° dH water) was then added to each tube. The swatches were then rinsed in the miniLOM at room temperature for 30 min at 30 rpm.
Rinse test in softeners (second rinse)
After the first rinse, the rinse liquor was carefully poured out. 30 ml of rinse solution (softener dissolved in 15° dH water) was then added to each tube. Three replicates (one replicate/tube) were used for each rinse condition (softener/DNase combination). 1 .0 ppm DNase was added to the tubes, and tubes without DNase were included as controls. The swatches were then rinsed in the tubes in the miniLOM at room temperature for 30 min at 30 rpm.
Step 3. GC-MS analysis of the rinsed items
After washing and rinsing, each swatch was centrifuged in a falcon tube containing a filter (HOZELOCK K3 kaldness filters, Aquacadabra, eBay) at 4000g for 5 min to remove excess water. This plastic filter separated the excess water from the swatch after centrifuging.
The three swatches from the same glass tube were then placed in one 20 mL GC-MS vial (Mikrolab Aarhus A/S, Aarhus, Denmark) and capped with silicone screw top lids (Mikrolab Aarhus A/S, Aarhus, Denmark). All vials were then analyzed by GC-MS, as described in Example 2.
Results
This example showed that the fragrance intensity on polyester T-shirts was increased for a variety of different perfume compounds in all tested softeners when the samples were rinsed according to the invention with a composition contained a DNase (Tables 5, 6 and 7).
Table 5. Fragrance intensity on polyester T-shirts rinsed in Dun-let Dream of Freshness softener with or without DNase (SEQ ID NO: 1 )

Table 7. Fragrance intensity on polyester T-shirts rinsed in Bamseline Dugfrisk softener with or without DNase (SEQ ID NO: 1 )
The above fragrances can be grouped into different perfume notes, i.e. top, heart or base notes based on their volatility as explained above in the description. It was found that the intensity of the heart note fragrances on polyester T-shirts was increased most in two of the three softeners, compared to the top notes and base notes, when the samples were rinsed according to the invention with a softener composition contained a DNase (Tables 8 and 9). As shown in Table, 9 however, this softener also resulted in a substantial increase in the top notes that was close to the increase observed for the heart notes. The third softener (Table 10) showed the largest increase in intensities in the top notes, compared to the heart notes and base notes, when the samples were rinsed in the softener containing a DNase.
