Description

The present invention relates to a detergent portion unit with at least one receiving chamber surrounded by a water-soluble film material, which in turn is filled with a highly concentrated textile detergent. The application also relates to a method for producing these detergent portion units.

Constantly changing requirements are placed on the packaging and supply forms of detergents and cleaning agents. For some time now, the main focus has been on the convenient dosing of detergents and cleaning agents by the consumer and the simplification of the work steps required to carry out a washing or cleaning process. A technical solution is offered by pre-portioned detergents or cleaning agents, for example foil bags with one or more receiving chambers for solid or liquid detergents or cleaning agents.

Liquid cleaning agents are generally produced by means of a sequential process in the course of which the ingredients of the cleaning agent are mixed with one another in chronological order. In order to achieve a homogeneous end product, the respective intermediate products and the end product are mixed with the input of energy. The end product is characterized not only by the most homogeneous possible distribution of active ingredients, but also by rheological properties that are suitable for handling by the consumer. The type and point in time when these rheological properties are set during the manufacturing process influences the efficiency of the process as well as the final product quality, since the rheological properties of the intermediate and end products are closely related to the energy input required for homogenization during the manufacturing process and to the mechanical energy input Load of the intermediate and end products and their components.

In addition to process-related aspects, the commercial success of a detergent portion unit is of course also determined by the ability to provide a product that meets consumer interest. An essential means of communicating product quality and product promise is its appearance, including the shape and color of the portion unit. While colored, ie non-white, liquid detergents can be obtained simply by adding appropriate dyes, the provision of white liquid detergents is more challenging because the opacifiers previously used to produce them are increasingly being viewed critically from an ecological point of view. Against this background, the provision of an ecologically acceptable opacifier is another development goal in the field of liquid detergents and cleaning agents.

In summary, the application was based on the object of providing visually appealing, concentrated detergent portion units and an efficient process for their production.

1. i) 0,1 bis 10 Gew.-% eines Trübungsmittels;
2. ii) 0,00001 bis 1 Gew.-% mindestens eines Farbmittels aus der Gruppe der roten, blauen oder violetten Farbmittel.

A first object of the present invention is a free-flowing detergent preparation, based on its total weight

1. i) from 0.1% to 10% by weight of an opacifying agent;
2. ii) 0.00001 to 1% by weight of at least one colorant from the group of red, blue or violet colorants.

The detergent preparation is flowable under standard conditions (20° C., 1013 mbar).

The essential components of the detergent preparation are an opacifier and a colorant from the group consisting of the red, blue or violet colorants. The combination of these two ingredients ensures a cloudy-white appearance of the detergent preparation that is stable over time.

Even if their use in some cases is questionable from an ecological point of view, the cloudy-white appearance described, which is stable over time, is also achieved when organic opacifying agents are used, for example polymeric organic opacifying agents. An exemplary group of polymeric organic opacifiers are the styrene-acrylate copolymers (INCI: styrene/acrylates copolymer).

Because of the aforementioned ecological reservations, the use of an opacifier from the group of inorganic opacifiers is preferred. The use of inorganic opacifiers from the group of salts of divalent cations is particularly preferred, with magnesium and calcium salts in particular, preferably from the group of magnesium chloride, magnesium sulfate, calcium chloride and calcium sulfate, being particularly preferred due to their availability and their advantageous technical properties.

Preferred salts have a solubility in water (20°C) above 400 g/l. The use of salts from the group consisting of magnesium chloride and calcium chloride is very particularly preferred.

The use of 0.3 to 8% by weight, preferably 0.4 to 6% by weight and in particular 0.5 to 4% by weight of a salt of divalent cations has been found to be suitable for achieving a cloudy white appearance that is stable over time proven.

As a second essential component, in addition to the opacifier, the detergent preparation contains at least one red, blue or violet colorant. The proportion by weight of the colorant in the total weight of the detergent preparation is preferably 0.0001 to 0.1% by weight of colorant. The detergent preparation contains a colorant or a mixture of two, three or more colorants. A colorant mixture can only include colorants of one color or colorants of different colors. Because of their optical Properties are preferred detergent preparations which contain at least one blue colorant.

In an alternative embodiment, the colorant is selected from the group of polymeric dyes. Suitable polymer dyes include conjugated chromogens (dye-polymer conjugates) and polymers with chromogens polymerized into their backbone. The group of these polymeric dyes include, for example, under the name Liquitint ^® commercially available colorants, such as Liquitint ^® Violet CT, conjugated with CMC CI Reactive Blue 19 with the product name AZO-CM-cellulose, alkoxylated polymeric triphenylmethane dyes or alkoxylated polymeric Thiphenfarbstoffe.

In another alternative embodiment, a dye-clay conjugate is used as the colorant. The group of these colorants includes, inter alia, conjugates of smectite clay or montmorillonite clay or hectorite clay or saponite clay with a cationic/basic dye from the group CI Basic Yellow 1 to 108, CI Basic Orange 1 to 69, CI Basic Red 1 to 118, CI Basic Violet 1 to 51, CI Basic Blue 1 to 164, CI Basic Green 1 to 14, CI Basic Brown 1 to 23, CI Basic Black 1 to 11. In particular, this group of colorants includes montmorillonite Basic Blue B7 CI 42595 Conjugate, Montmorillonite Basic Blue B9 CI 52015 Conjugate, Montmorillonite Basic Violet V3 CI 42555 Conjugate, Montmorillonite Basic Green G1 CI 42040 Conjugate, Montmorillonite Basic Red R1 CI 45160 Conjugate, Montmorillonite CI Basic Black 2 Conjugate, Hectorite Basic Blue B7 CI 42595 Conjugate, Hectorite Basic Blue B9 CI 52015 Conjugate, Hectorite Basic Violet V3 CI 42555 Conjugate, Hectorite Basic Green G1 CI 42040 Conjugate, Hectorite Basic Red R1 CI 45160 Conjugate, Hectorite CI Basic Black 2 Conjugate, Saponite Basic Blue B7 CI 42595 Conjugate, Saponite Basic Blue B9 CI 52015 Conjugate, Saponite Basic Violet V3 CI 42555 Conjugate, Saponite Basic Green G1 CI 42040- conjugate, Saponit Basic Red R1 CI 45160 conjugate, Saponit CI Basic Black 2 conjugate and mixtures thereof.

The use of colorants from the group of photobleaching agents, in particular photobleaching agents from the group of phthalocyanine sulfonates, has proven to be technically particularly advantageous. Suitable photobleaches for example, aluminum phthalocyanine, or zinc phtalocyanine sulfonate, or mixtures thereof, as are commercially available under the name Tinolux ^®.

In a technically advantageous variant, the free-flowing detergent preparation also contains, based on its total weight
vi) from 0.5% to 4%, preferably from 0.5% to 3% and more preferably from 0.5% to 2% by weight of the salt of a monovalent cation.

The addition of the monovalent cation intensifies the cloudy white appearance of the detergent preparation. At the same time, the resulting compositions are distinguished by optimal viscosity properties. In particular, the addition of the monovalent cation in large proportions by weight brings about sufficient turbidity without increasing the viscosity of the detergent preparation in a way that makes it more difficult to convey it in pipeline systems. Finally, the addition of the salt of a monovalent cation reduces the temperature dependence of the viscosity of the free-flowing detergent composition and in this way simplifies its processing.
In addition, the use of monovalent metal salts, in particular the use of sodium chloride, improves the storage stability, in particular the storage stability in the event of temperature fluctuations.

Preferred monovalent cations are selected from the group of monovalent metallic cations. Preferred salts of monovalent cations are selected from the group sodium chloride, potassium chloride, sodium sulfate, sodium carbonate, potassium sulfate, potassium carbonate, sodium bicarbonate, potassium bicarbonate, most preferably from the group sodium chloride, due to their availability and low cost.

The main types of structured system used in practice are based on dispersed lamellar, spherulitic and attenuated lamellar phases. The free-flowing detergent preparation preferably contains a spherulitic phase. Spherulitic phases comprise spherical bodies, commonly referred to in the art as spherulites, in which surfactant bilayers are arranged as concentric shells. The spherulites are dispersed in an aqueous phase in the manner of a classic emulsion, interacting and forming a structured system. Preferred free-flowing detergent preparations comprise lamellar spherulites, preferably with a maximum diameter of 10 to 100 μm, particularly preferably with a maximum diameter of 25 to 50 μm.

The free-flowing detergent preparation preferably has a yield point (TA Instruments AR 2000 rotary rheometer, 20° C., cone and plate with a diameter of 40 mm, 2° cone angle) above 0.1 Pa, preferably above 0.3 Pa.

The rheological properties of the first free-flowing detergent preparation are the reason for its efficient processability and also form the basis of its advantageous optical properties, including its cloudy-white appearance.

Nephelometric Turbidity Unit (NTU) is a commonly used measure of transparency. It is a unit used, for example, in water treatment for turbidity measurements, e.g. in liquids. It is the unit of turbidity measured with a calibrated nephelometer. High NTU values are measured for opaque compositions while low values are determined for clear compositions.

The HACH Turbidimeter 2100Q turbidimeter from the Hach Company, Loveland, Colorado (USA) is used with the calibration substances StablCal Solution HACH (20 NTU), StablCal Solution HACH (100 NTU) and StablCal Solution HACH (800 NTU) , all of which can also be ordered from the Hach Company. The measurement is filled with the composition to be examined in a 10 ml measuring cuvette with a cap and the measurement is carried out at 20.degree.

At an NTU value (at 20° C.) of 60 or more, moldings have a perceptible turbidity, which can be seen with the naked eye in the context of the invention. The turbidity (HACH Turbidimeter 2100Q, 20° C., 10 ml cuvette) of the liquid detergent containing surfactants is preferably above 60 NTU, preferably above 100 NTU and in particular above 400 NTU.

For the ecological reasons mentioned at the outset, the free-flowing detergent preparation is preferably free from organic opacifiers. "Free from" as used in this context means that the respective ingredient is present in the preparation in an amount <1% by weight, preferably <0.1% by weight, more preferably <0.01% by weight. In particular, such a component is then not intentionally added. In particular, the free-flowing detergent preparations preferably contain no styrene-acrylate copolymers (INCI: styrene/acrylates copolymer).

The flowable detergent preparation can be free of enzymes and/or fragrances. These components are not included in particular because they can adversely affect the turbidity and thus the appearance of the formulation.

For example, free-flowing detergent preparations which, based on their total weight, contain less than 2% by weight, less than 1% by weight, preferably less than 0.1% by weight and in particular no enzyme preparation, are preferred.

Flowable detergent preparations which, based on their total weight, contain less than 2% by weight, preferably less than 1% by weight, particularly preferably less than 0.1% by weight and in particular no fragrance, are also preferred.

In an alternative embodiment, the flowable detergent preparation contains at least one optical brightener, preferably a stilbene-type optical brightener. This is contained in the free-flowing detergent preparation, based on its total weight, in an amount above 0% by weight, but preferably in an amount below 1% by weight, particularly preferably in an amount below 0.6% by weight. Brighteners of the stilbene type for use in the flowable detergent preparation are preferably selected from the group consisting of triazinyl derivatives of 4,4'-diamino-2,2'-stilbenesulfonic acid. The economically most important stilbene derivatives are DAS1 (disodium 4,4-bis[(4-anilino-6-morpholino-1,3,5-triazin-2-yl)amino]-stilbene-2,2-disulphonate) and DSBP ( disodium 4,4-bis(2-sulfostyryl)biphenyl).

1. a) mindestens eine erste Aufnahmekammer,
2. b) mindestens einen, diese erste Aufnahmekammer umgebenden wasserlöslichen Film sowie
3. c) mindestens eine in der ersten Aufnahmekammer befindliche erfindungsgemäße fließfähige Waschmittelzubereitung.

In a particularly preferred embodiment, the free-flowing detergent preparation is enclosed in a water-soluble film to form a detergent portion unit. Corresponding detergent portion units include

1. a) at least one first receiving chamber,
2. b) at least one water-soluble film surrounding this first receiving chamber and
3. c) at least one free-flowing detergent preparation according to the invention located in the first receiving chamber.

It is preferred to reshape the water-soluble film in a deep-drawing apparatus and to combine it with the liquid detergent to form a detergent portion unit.

The water-soluble film in which the flowable detergent composition is packaged may comprise one or more structurally distinct water-soluble polymer(s). Particularly suitable as water-soluble polymer(s) are polymers from the group of (possibly acetalized) polyvinyl alcohols (PVAL) and their copolymers.

Water-soluble films for producing the water-soluble casing are preferably based on a polyvinyl alcohol or a polyvinyl alcohol copolymer whose molecular weight is in the range from 10,000 to 1,000,000 gmol ^-1 , preferably from 20,000 to 500,000 gmol ^-1 , particularly preferably from 30,000 to 100,000 gmol ^-1 and in particular from 40,000 to 80,000 gmol ^-1 .

The preparation of the polyvinyl alcohol and polyvinyl alcohol copolymers typically involves the hydrolysis of intermediate polyvinyl acetate. Preferred polyvinyl alcohols and polyvinyl alcohol copolymers have a degree of hydrolysis of 70 to 100 mol %, preferably 80 to 90 mol %, particularly preferably 81 to 89 mol % and in particular 82 to 88 mol %.

In addition to vinyl alcohol, preferred polyvinyl alcohol copolymers include an ethylenically unsaturated carboxylic acid, its salt or its ester. Such polyvinyl alcohol copolymers particularly preferably contain, in addition to vinyl alcohol, sulfonic acids such as 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS), acrylic acid, methacrylic acid, acrylic esters, methacrylic esters or mixtures thereof; among the esters, C _1-4 -alkyl esters or - hydroxyalkyl esters are preferred. Other suitable monomers are ethylenically unsaturated dicarboxylic acids, for example itaconic acid, maleic acid, fumaric acid and mixtures thereof.

Suitable water-soluble films are sold, for example, by MonoSol LLC under the designation M8630, M8720, M8310, C8400 or M8900. Other suitable films include films with the label Solublon ^® PT, Solublon ^® GA, Solublon KC ^® or Solublon ^® KL by Aicello Chemical Europe GmbH, or VF-HP film available from Kuraray.

The water-soluble films can contain additional active substances or fillers, but also plasticizers and/or solvents, in particular water, as further ingredients.

The group of further active ingredients includes, for example, materials which protect the ingredients of preparation (A) enclosed by the film material from decomposition or deactivation by exposure to light. Antioxidants, UV absorbers and fluorescent dyes have proven to be particularly suitable here.

For example, glycerol, ethylene glycol, diethylene glycol, propanediol, 2-methyl-1,3-propanediol, sorbitol or mixtures thereof can be used as plasticizers.

To reduce their coefficient of friction, the surface of the water-soluble film can optionally be powdered with fine powder. Sodium aluminosilicate, silica, talc and amylose are examples of suitable powdering agents.

It is particularly preferred if the detergent portion unit has a plurality of receiving chambers.

The several receiving chambers of the detergent portion unit can be arranged spatially next to one another or one above the other (stacked). These technical advantages are particularly obvious in the case of detergent portion units with receiving chambers which at least partially enclose one another. In preferred embodiments, the detergent portion unit has at least two receiving chambers, one receiving chamber being at least partially surrounded by at least one further receiving chamber. It is also very particularly preferred if the detergent portion unit has at least one further receiving chamber which is filled with a colored detergent preparation.

A detergent portion unit preferred according to the invention has at least two receiving chambers which are surrounded by a water-soluble film, one receiving chamber being filled with the free-flowing detergent preparation and the other receiving chamber being filled with a second colored detergent preparation different from the free-flowing detergent preparation.

Another exemplary preferred detergent portion unit comprises at least three receiving chambers, which are surrounded by a water-soluble film, one receiving chamber being filled with the free-flowing detergent preparation and at least two other receiving chambers being filled separately from one another with a second and a third colored detergent preparation that are different from one another and from the free-flowing detergent preparation are.

In an alternative embodiment, the detergent portion unit has at least four receiving chambers, which are surrounded by a water-soluble film, with one receiving chamber being filled with the free-flowing detergent preparation and the other three receiving chambers being separated from one another with a second and a third and a fourth from one another and from the free-flowing detergent preparation different colored detergent preparations are filled.

A second subject of this application is a method for cleaning textiles, in which a previously described free-flowing detergent preparation or a previously described detergent portion unit is introduced into the wash liquor of a textile washing machine.

1. a) Bereitstellen einer ersten fließfähigen Zusammensetzung, enthaltend Tensid, Fettsäure und Lösungsmittel;
2. b) Einbringen des Salzes eines zweiwertigen Kations und eines Farbmittels aus der Gruppe der roten, blauen oder violetten Farbmittel in die flüssige Zusammensetzung unter Ausbildung einer Salz- und Farbmittel-haltigen Zusammensetzung;
3. c) Mischen der Salz- und Farbmittel-haltigen Zusammensetzung;
4. d) gegebenenfalls Einschließen der Salz-haltigen Zusammensetzung in einem wasserlöslichen Film.

A third subject matter of this application is a process for producing a detergent preparation according to the invention, comprising the steps:

1. a) providing a first flowable composition containing surfactant, fatty acid and solvent;
2. b) introducing the salt of a divalent cation and a colorant from the group consisting of red, blue or violet colorants into the liquid composition to form a salt and colorant-containing composition;
3. c) mixing the salt and colorant-containing composition;
4. d) optionally enclosing the salt-containing composition in a water-soluble film.

The starting point of the method according to the invention is the provision of a first free-flowing detergent preparation containing surfactant, fatty acid and solvent. The preparation of this preparation can be carried out in advance in a continuous or discontinuous manner. For example, a line system preferably provided with mixing devices, in which the components of the preparation are brought into contact with one another and mixed, is suitable for continuous production. Due to the reduced outlay in terms of equipment and operations, however, it is preferred if the first free-flowing detergent preparation is provided discontinuously. For example, providing the preparation as a storable mixture (master batch) in a stirred tank or some other container is suitable for this. Such a container not only enables the storage of intermediate products, but also makes it possible to buffer any fluctuations in the throughput rates of the subsequent process steps, which are preferably carried out continuously. It is therefore also preferred if the first free-flowing detergent preparation is introduced continuously from a buffer container into a main line.

In a further process step, the salt of a divalent cation is introduced into the liquid composition. This is preferably done via a secondary line, through which the salt is continuously introduced into the main line. In order to simplify the procedure, it is preferred if the salt of a divalent cation is introduced into the main line via a secondary line in the form of a carrier liquid-particle dispersion.

The addition of the salt of a divalent cation results in the formation of a cloudy white appearance and a sufficiently high and stable viscosity, which is advantageous for the further course of the process and subsequent use. The development of both physical properties of the liquid composition is promoted by mixing all the ingredients. It is therefore also preferred to provide the outlet opening of the secondary line, through which the salt of a divalent cation is introduced into the main line via a secondary line, in the effective area of a mixing device which is mounted within the main line. The mixing device can be a static or a dynamic mixer.

The resulting metal salt-containing composition can subsequently be expanded or differentiated by adding further active substances. The addition of an active substance from the group of optionally encapsulated fragrances, enzymes, preservatives, bitter substances, preferably from the group of optionally encapsulated fragrances, enzymes and preservatives, is particularly suitable for this purpose, which is preferably carried out after the Introduction of the salt of a divalent cation, is introduced into the main line via a side line. It is particularly preferred, after the introduction of the salt of a divalent cation, to introduce an active substance from the group of fragrances or enzymes into the main line via a secondary line.

The additional active can be added to the composition before mixing the salt and colorant-containing composition or after this step.
