Description

REFERENCE TO A SEQUENCE LISTING

This application contains a Sequence Listing in computer readable form, which is incorporated herein by reference.

FIELD OF THE INVENTION

The present disclosure relates to cleaning compositions that include a mannanase enzyme and a dye control agent. The present disclosure also relates to methods of making and using such cleaning compositions. The present disclosure also relates to the use of a dye control agent.

BACKGROUND OF THE INVENTION

During the laundering process, substantive dyes from fabrics may be released into the wash liquor and then may deposit onto other fabrics. Soils, whether on fabrics or in the wash liquor can present particular challenges with regard to dye transfer. For example, the dyes may have a particular affinity for soils due to chemical attractions between the soil material and the dyes, often involving hardness ions which are able to bridge anionic dyes with anionic soils. The consequences of such interactions can be localized or general discoloration of the fabric. Furthermore, the complex formed by the soil and the dye may result in soils that are more resistant to removal by detergent cleaning adjuncts; in other words, the transferred dye can inhibit the performance of cleaning compositions and processes.
There is a need for improved cleaning compositions that provide cleaning and/or whiteness benefits to fabrics, particularly on fabric loads that include dyes.

SUMMARY OF THE INVENTION

The present invention provides a cleaning composition comprising a mannanase enzyme comprising a polypeptide having mannan endo-1,4-beta-mannosidase activity (EC 3.2.1 .78) that catalyzes the hydrolysis of 1 ,4-3-D-mannosidic linkages in mannans, galactomannans and/or glucomannans, and/or optionally according to SEQ ID NO:1 herein or a variant having at least 60% sequence identity to SEQ ID NO:1 or according to SEQ ID NO:2 herein or a variant having at least 81% sequence identity to SEQ ID NO: 2 or according to SEQ ID NO:3 herein or a variant having at least 75% sequence identity to SEQ ID NO:3 or according to SEQ ID NO:4 herein or a variant having at least 65% sequence identity to SEQ ID NO: 4 according to SEQ ID NO:5 herein or a variant having at least 75% sequence identity to SEQ ID NO:5; and a dye control agent.

DETAILED DESCRIPTION OF THE INVENTION

The present disclosure relates to cleaning compositions comprising a mannanase enzyme and particular dye transfer agents. Without wishing to be bound by theory, it is believed that the dye transfer agents inhibit interaction between dyes in the wash liquor and certain soils such as soils of microbial origin, including extracellular DNA that are substrates for the mannanase enzyme, thereby leading to decreased dye redeposition and increased enzyme performance. Additionally, DNA-based soil material can have particularly adhesive properties and may attract other soils; therefore, efficient galactanase enzyme activity can help reduce soil redeposition, whiteness losses, and/or dinginess. This combination of reduced dye transfer and enhanced detergency leads to effective textile cleanliness and contrast between white and colored regions of textiles.

Preferably the compositions are in liquid form. They may be made by any process chosen by the formulator, including by a batch process, a continuous loop process, or combinations thereof.
When in the form of a liquid, the compositions of the invention may be aqueous (typically above 2 wt% or even above 5 or 10 wt% total water, up to 90 or up to 80wt% or 70 wt% total water) or non-aqueous (typically below 2 wt% total water content). Typically the compositions of the invention will be in the form of an aqueous solution or uniform dispersion or suspension of optical brightener, DTI and optional additional adjunct materials, some of which may normally be in solid form, that have been combined with the normally liquid components of the composition, such as the liquid alcohol ethoxylate nonionic, the aqueous liquid carrier, and any other normally liquid optional ingredients.

The high shear viscosity at 20s-1 and low shear viscosity at 0.05-1 can be obtained from a logarithmic shear rate sweep from 0.1-1 to 25-1 in 3 minutes time at 21C.

The cleaning and/or treatment compositions in the form of a liquid herein can be prepared by combining the components thereof in any convenient order and by mixing, e.g., agitating, the resulting component combination to form a phase stable liquid detergent composition. In a process for preparing such compositions, a liquid matrix is formed containing at least a major proportion, or even substantially all, of the liquid components, e.g., nonionic surfactant, the non-surface active liquid carriers and other optional liquid components, with the liquid components being thoroughly admixed by imparting shear agitation to this liquid combination. For example, rapid stirring with a mechanical stirrer may usefully be employed. While shear agitation is maintained, substantially all of any anionic surfactants and the solid form ingredients can be added. Agitation of the mixture is continued, and if necessary, can be increased at this point to form a solution or a uniform dispersion of insoluble solid phase particulates within the liquid phase. After some or all of the solid-form materials have been added to this agitated mixture, particles of any enzyme material to be included, e.g., enzyme granulates, are incorporated. As a variation of the composition preparation procedure hereinbefore described, one or more of the solid components may be added to the agitated mixture as a solution or slurry of particles premixed with a minor portion of one or more of the liquid components. After addition of all of the composition components, agitation of the mixture is continued for a period of time sufficient to form compositions having the requisite viscosity and phase stability characteristics. Frequently this will involve agitation for a period of from about 30 to 60 minutes.
The adjunct ingredients in the compositions of this invention may be incorporated into the composition as the product of the synthesis generating such components, either with or without an intermediate purification step. Where there is no purification step, commonly the mixture used will comprise the desired component or mixtures thereof (and percentages given herein relate to the weight percent of the component itself unless otherwise specified) and in addition unreacted starting materials and impurities formed from side reactions and/or incomplete reaction. For example, for an ethoxylated or substituted component, the mixture will likely comprise different degrees of ethoxylation/substitution.

An enzyme is deemed to have activity towards xyloglucan if the pure enzyme has a specific activity of greater than 50000 XyloU/g according to the following assay at pH 7.5.
The xyloglucanase activity is measured using AZCL-xyloglucan from Megazyme, Ireland as substrate (blue substrate).
A solution of 0.2% of the blue substrate is suspended in a 0.1M phosphate buffer pH 7.5, 20°C under stirring in a 1.5ml Eppendorf tubes (0.75ml to each), 50 microlitres enzyme solution is added and they are incubated in an Eppendorf Thermomixer for 20 minutes at 40°C, with a mixing of 1200 rpm. After incubation the coloured solution is separated from the solid by 4 minutes centrifugation at 14,000 rpm and the absorbance of the supernatant is measured at 600nm in a 1cm cuvette using a spectrophotometer. One XyloU unit is defined as the amount of enzyme resulting in an absorbance of 0.24 in a 1cm cuvette at 600nm.
Only absorbance values between 0.1 and 0.8 are used to calculate the XyloU activity. If an absorbance value is measured outside this range, optimization of the starting enzyme concentration should be carried out accordingly.

Enzymatic activity towards amorphous cellulose substrates

An enzyme is deemed to have activity towards amorphous cellulose if the pure enzyme has a specific activity of greater than 20000 EBG/g according to the following assay at pH 7.5. Chemicals used as buffers and substrates were commercial products of at least reagent grade. Endoglucanase Activity Assay Materials:

0.1M phosphate buffer pH 7.5
Cellazyme C tablets, supplied by Megazyme International, Ireland.
Glass microfiber filters, GF/C, 9cm diameter, supplied by Whatman.

Method:

In test tubes, mix 1ml pH 7.5 buffer and 5ml deionised water.
Add 100 microliter of the enzyme sample (or of dilutions of the enzyme sample with known weight:weight dilution factor). Add 1 Cellazyme C tablet into each tube, cap the tubes and mix on a vortex mixer for 10 seconds. Place the tubes in a thermostated water bath, temperature 40°C. After 15, 30 and 45 minutes, mix the contents of the tubes by inverting the tubes, and replace in the water bath. After 60 minutes, mix the contents of the tubes by inversion and then filter through a GF/C filter. Collect the filtrate in a clean tube.
Measure Absorbance (Aenz) at 590nm, with a spectrophotometer. A blank value, Awater, is determined by adding 100µl water instead of 100 microliter enzyme dilution. $Calculate Adelta = Aenz - Awater .$
Adelta must be <0.5. If higher results are obtained, repeat with a different enzyme dilution factor.
Determine DFO.1, where DFO.1 is the dilution factor needed to give Adelta = 0.1 . Unit Definition: 1 Endo-Beta-Glucanase activity unit (1 EBG) is the amount of enzyme that gives Adelta = 0.10, under the assay conditions specified above. Thus, for example, if a given enzyme sample, after dilution by a dilution factor of 100, gives Adelta= 0.10, then the enzyme sample has an activity of 100 EBG/g.
