Description

The present invention relates to a detergent preparation based on surfactants and enzymes. Furthermore, the application relates to detergent portion units which comprise this detergent preparation and a method for washing textiles using the detergent preparation or the detergent portion unit.

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.

A trend that is relevant for the production of these foil bags is the miniaturization of these foil bags. The background to this development, in addition to greater consumer acceptance due to simplified handling, are sustainability aspects in particular, for example in relation to transport volumes and costs and the amount of packaging used.

The concentration of modern detergents, especially modern liquid detergents, usually affects their optical and rheological properties, affects the storage stability of these detergents and can affect their cleaning performance, especially when the high concentration of active ingredients leads to intolerance.

The European patent EP 2 254 979 B1 describes solid textile detergents with a small proportion of linear alkylbenzene sulfonic acid, which can also contain pectinases in addition to other enzymes.

In the international patent application WO 2015/121133A1 describes liquid textile detergents with a high water content which, in addition to small amounts of linear alkylbenzene sulfonic acid, also contain pectinase.

The application was based on the object of providing optically attractive, concentrated, free-flowing detergent preparations which can be produced in a simple and efficient manner, have a good shelf life and are distinguished in particular by good cleaning results. In particular, the detergent preparation should be able to be packaged in water-soluble sachets and be based predominantly on ingredients that can be produced at least in part from renewable raw materials.

1. a) 2 bis 20 Gew.-% anionisches Tensid aus der Gruppe der C_8-18-Alkylbenzolsulfonate;
2. b) 0,05 bis 2 Gew.-% einer Zubereitung eines pektinolytischen Enzyms;
3. c) weniger als 20 Gew.-% Wasser.

A first subject of the application is a free-flowing detergent preparation containing, based on its total weight,

1. a) 2 to 20% by weight of anionic surfactant from the group consisting of the C _8-18 -alkylbenzene sulfonates;
2. b) from 0.05% to 2% by weight of a preparation of a pectinolytic enzyme;
3. c) less than 20% by weight of water.

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

A first essential component of the detergent preparation is the C _8-18 -alkylbenzene sulfonate, which is contained in the detergent preparation in proportions by weight of 5 to 20% by weight. Preferred detergent preparations contain, based on their total weight, 7 to 17% by weight, preferably 9 to 15% by weight, of C _8-18 -alkylbenzene sulfonate.

in der
R' und R" unabhängig H oder Alkyl sind und zusammen 8 bis 18, vorzugsweise 9 bis 15 und insbesondere 9 bis 13 C-Atome enthalten, und Y⁺ ein einwertiges Kation oder den n-ten Teil eines n-wertigen Kations (insbesondere Na⁺) bedeuten.Preferred C _8-18 alkyl benzene sulphonates have the general formula (I),

in the
R' and R" are independently H or alkyl and together contain 8 to 18, preferably 9 to 15 and in particular 9 to 13 carbon atoms, and Y ⁺ is a monovalent cation or the nth part of an n-valent cation (in particular Na ⁺ ) mean.

In addition to the C _8-18 -alkylbenzene sulfonates described above, the detergent preparation may contain other anionic surfactants. The group of these further surfactants includes, for example, the alkyl ether sulfates, olefin sulfonates, C ₁₂ -C ₁₈ alkane sulfonates, ester sulfonates, alk(en)yl sulfates and mixtures thereof. Nevertheless, it has been found that the detergent preparation according to the invention achieves good washing results even without using these additional anionic surfactants. For reasons of complexity reduction, the greatest possible miniaturization of the required detergent portion unit and an improved sustainability profile, it is therefore preferred if the detergent preparation, based on its total weight, contains less than 10% by weight, preferably less than 6% by weight and in particular less than 2 Wt .-% contains anionic surfactant from the group of alkyl ether sulfates. In addition, it can be advantageous if the detergent preparation, based on its total weight, in addition to the anionic surfactant from the group of C _8-18 alkyl benzene sulfonates less than 10 wt .-%, preferably less than 6 wt .-% and in particular less than 2% by weight of additional anionic surfactant.

The use of fatty acids has proven advantageous for stability and cleaning performance. Preferred detergent preparations therefore contain, based on their total weight, 4 to 12% by weight, preferably 6 to 10% by weight, of fatty acid. Particularly preferred fatty acids are selected from the group of caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, oleic acid, linoleic acid and mixtures thereof. In the context of the application, the fatty acids are not assigned to the group of anionic surfactants.

The use of nonionic surfactants is advantageous for the cleaning performance of the detergent preparations. The proportion by weight of the nonionic surfactants in the total weight of the detergent preparation is preferably 15 to 34% by weight, preferably 18 to 30% by weight.

Preferred nonionic surfactants are from the group of ethoxylated primary C _8-18 alcohols, preferably the ethoxylated primary C _8-18 alcohols with a degree of alkoxylation ≥ 4, particularly preferably the C _12-14 alcohols with 4 EO or 7 EO, the C _9-11 alcohols with 7 EO, C _13-15 alcohols with 5 EO, 7 EO or 8 EO, C _13-15 oxo alcohols with 7 EO, C _12-18 alcohols with 5 EO or 7 EO EO, in particular the C _12-18 fatty alcohols with 7 EO or the C _13-15 oxo alcohols with 7 EO.

With regard to the rheological properties of the detergent preparation, its processability and cleaning action, it has proven advantageous to use nonionic surfactant and anionic surfactant in a weight ratio of 2:1 to 3:2.

The detergent preparation contains 0.05 to 2% by weight of a preparation of a pectinolytic enzyme as the second essential component. In preferred embodiments, the proportion by weight of this preparation in the total weight of the detergent preparation is 0.1 to 0.4% by weight.

Within the scope of the present invention, the pectinolytic enzymes include enzymes with the designations pectinase, pectate lyase, pectinesterase, pectin demethoxylase, pectin methoxylase, pectin methylesterase, pectase, pectin methylesterase, pectinoesterase, pectin pectyl hydrolase, pectin endopolymerase, endopolygalacturonase, pectolase, pectin hydrolase, pectin polygalacturonase Polygalacturonase, Poly-α-1,4-galacturonide glycanohydrolase, Endogalacturonase, Endo-D-galacturonase, Galacturan 1,4-α-galacturonidase, Exopolygalacturonase, Poly(galacturonate) hydrolase, Exo-D-galacturonase, Exo-D-galacturonanase, exopoly-DGalacturonase, exo-poly-α-galacturonosidase, exopolygalacturonosidase or exopolygalacturanosidase. The use of pectate lyases is very particularly preferred.

Within the EC classification of enzymes, the numerical classification system for enzymes, the pectinolytic enzymes belong in particular to the enzyme classes (engl. "Enzyme Commission number") EC 3.1.1.11, EC 3.2.1.15, EC 3.2.1.67 and EC 3.2. 1.82 and consequently belong to the third of the six main classes of enzymes, the 10 hydrolases (EC.3. below to the glycosylases (EC. 3.2.-.-) and again below to the glycosidases (EC. 3.2.1.-), i.e. enzymes that O- and/or hydrolyze S-glycosyl compounds Pectinolytic enzymes are therefore particularly effective against residues on crockery containing pectic acid and/or other galacturonans and catalyze their hydrolysis.

According to the invention, pectate lyases are enzymes which catalyze the non-hydrolytic cleavage of pectate according to an endo mechanism.

Examples of suitable pectinolytic enzymes are those under the trade names Gamanase®, ^{Pektinex AR®} , X- ^Pect® or ^Pectaway® from the company Novozymes, under the trade names Rohapect ^UF® , Rohapect ^TPL® , Rohapect ^PTE100® , Rohapect ^MPE® , Rohapect MA plus HC, Rohapect ^DA12L® , Rohapect ^10L® , Rohapect ^B1L® available from AB Enzymes and under the tradename ^Pyrolase® from Diversa Corp., San Diego, CA, USA, enzymes and enzyme preparations.

In addition to the actual enzyme protein, an enzyme preparation includes other components such as enzyme stabilizers, carrier materials or fillers. The enzyme protein usually makes up only a fraction of the total weight of the enzyme preparation. Preferably used enzyme preparations contain between 0.1 and 40% by weight, preferably between 0.2 and 30% by weight, more preferably between 0.4 and 20% by weight and most preferably between 0.8 and 10% by weight % of enzyme protein. In such compositions, an enzyme stabilizer can be included in an amount of 0.05 to 35% by weight, preferably 0.05 to 10% by weight, based on the total weight in the enzyme composition.

The protein concentration can be determined using known methods, for example the BCA method (bicinchoninic acid; 2,2'-biquinolyl-4,4'-dicarboxylic acid) or the Biuret method. In this regard, the active protein concentration is determined via a titration of the active centers using a suitable irreversible inhibitor (for proteases, for example, phenylmethylsulfonyl fluoride (PMSF)) and determination of the residual activity.

Preferred preparations of pectinolytic enzymes, in particular pectate lyase preparations, contain, based on their total weight, a proportion by weight of active protein of 0.1 and 40% by weight, preferably 0.2 and 30% by weight.

In combination with the preparations of pectinolytic enzymes described above, in particular in combination with pectate lyase preparations, other enzyme preparations are used with particular preference in the detergent preparation. The proportion by weight of these further enzyme preparations in the total weight of the detergent preparation is preferably 2 to 8% by weight and in particular 3 to 6% by weight.

It is preferred if the detergent preparation according to the invention contains at least one enzyme preparation, preferably at least 3 enzyme preparations of enzymes from the group amylase, mannanase, protease, cellulase and lipase in addition to the pectinolytic enzyme preparation, in particular in addition to the pectylase preparation.

It is preferred according to the invention if at least one protease is present as the enzyme. A protease is an enzyme that cleaves peptide bonds by hydrolysis. Each of the enzymes from class E.C. 3.4 is included according to the invention (comprising each of the thirteen subclasses included). "Protease activity" is present according to the invention if the enzyme has proteolytic activity (EC 3.4). Various types of protease activity are known: the three main types are: trypsin-like, in which cleavage of the amide substrate occurs after the amino acids Arg or Lys at P1; chymotrypsin-like, with cleavage occurring after one of the hydrophobic amino acids at P1; and elastase-like, with cleavage of the amide substrate to Ala at P1.

Surprisingly, it was found that a protease of the alkaline protease type from Bacillus lentus DSM 5483 or a protease sufficiently similar thereto (based on the sequence identity), which has several of these changes in combination, is particularly suitable for use in the liquid detergent preparations according to the invention and therein is advantageously improved stabilized. Advantages of using this protease thus result in particular with regard to washing performance and/or stability.

Very particularly preferably, the detergent preparation according to the invention contains protease of the alkaline protease type from Bacillus lentus DSM 5483 or a protease sufficiently similar thereto (based on the sequence identity), which has several of these changes in combination,

The proportion by weight of the protease preparation in the total weight of the detergent preparation is preferably 0.5 to 5% by weight, in particular 1.0 to 4% by weight.

As a further preferred optional ingredient, the detergent preparations contain a cellulase preparation. Synonymous terms can be used for cellulases, in particular Endoglucanase, endo-1,4-beta-glucanase, carboxymethyl cellulase, endo-1,4-beta-D-glucanase, beta-1,4-glucanase, beta-1,4-endoglucan hydrolase, celludextrinase or avicelase. The decisive factor in determining whether an enzyme is a cellulase within the meaning of the invention is its ability to hydrolyze 1,4-β-D-glucosidic bonds in cellulose.

Cellulases (endoglucanases, EG) suitable according to the invention include, for example, fungal compositions rich in endoglucanase (EG), which are offered by the company Novozymes under the trade name ^Celluzyme® . The products Endolase ^® and Carezyme ^® , which are also available from the company Novozymes, are based on the 50 kD EG or the 43 kD EG from Humicola insolens DSM 1800. Other usable commercial products from this company are Cellusoft ^® , Renozyme ^® and Celluclean ^® . Also usable are, for example, cellulases which are available from AB Enzymes, Finland, under the trade names ^Ecostone® and ^Biotouch® and which are at least partly based on the 20 kD EG from Melanocarpus. Other cellulases from the company AB Enzymes are Econase ^® and Ecopulp ^® . Other suitable cellulases are from Bacillus sp. CBS 670.93 and CBS 669.93, wherein the Bacillus sp. CBS 670.93 is available from the Danisco/Genencor company under the tradename ^Puradax® . Other usable commercial products from the company Danisco/Genencor are “Genencor detergent cellulase L” and ^IndiAge® Neutra.

The proportion by weight of the cellulase preparation in the total weight of the detergent preparation is preferably 0.05 to 1% by weight, in particular 0.1 to 0.5% by weight.

According to the invention, it is furthermore preferred if the detergent preparation according to the invention contains at least one lipase preparation. According to the invention, preferred lipases are selected from at least one enzyme from the group formed by triacylglycerol lipase (EC 3.1.1.3), and lipoprotein lipase (EC 3.1.1.34) and monoglyceride lipase (EC 3.1.1.23).

According to the invention, preferred lipase preparations are the commercial products marketed by Amano Pharmaceuticals under the names Lipase M- ^AP10® , Lipase ^LE® and Lipase ^F® (also Lipase ^JV® ). For example, the lipase F ^® is naturally present in Rhizopus oryzae. For example, the lipase M- ^AP10® is naturally present in Mucor javanicus.

A highly preferred lipase can be obtained commercially under the trade name ^Lipex® from the company Novozymes (Denmark) and can be used advantageously in the detergent preparations according to the invention. The lipase ^Lipex® 100 L is particularly preferred.

Preferred detergent preparations are characterized in that they contain from 0.01 to 1% by weight, in particular from 0.02 to 0.4% by weight, of lipase preparation, based on their total weight.

The detergent preparations according to the invention can additionally contain at least one mannanase preparation as an enzyme. A mannanase catalyses the hydrolysis of 1,4-beta-D-mannosidic bonds in mannans, galactomannans, glucomannans and galactoglucomannans. According to enzyme nomenclature, said mannanases are referred to as E.C. 3.2.1.78 classified.

Suitable mannanases are available under the trade name ^Mannaway® from Novozymes.

The proportion by weight of the mannanase preparation in the total weight of the detergent preparation is preferably 0.01 to 0.5% by weight, in particular 0.02 to 0.2% by weight.

The detergent preparations preferably contain at least one amylase, in particular an α-amylase. As an enzyme, α-amylases (EC 3.2.1.1) hydrolyze internal α-1,4-glycosidic bonds of starch and starch-like polymers. The α-amylases from Bacillus licheniformis, from B. amyloliquefaciens and from B. stearothermophilus and their improved further developments for use in detergents or cleaning agents can be mentioned as examples. The enzyme from B. licheniformis is available from Novozymes under the trade name ^Termamyl® and from Genencor under the trade name ^Purastar® ST. Further development products of these α-amylases are available from Novozymes under the trade names ^Duramyl® and ^Termamyl® ultra, from Genencor under the name ^Purastar® OxAm and from Daiwa Seiko Inc., Tokyo, Japan, as ^Keistase® . The α-amylase from B. amyloliquefaciens is marketed by the company Novozymes under the name ^BAN® , and variants derived from the α-amylase from B. stearothermophilus under the names ^BSG® and ^Novamyl® , also from the company Novozymes. Examples of α-amylases from other organisms are the further developments of α-amylase from Aspergillus niger and A. oryzae available under the trade name ^Fungamyl® from Novozymes.

The proportion by weight of the amylase preparation, in particular the α-amylase preparation, in the total weight of the detergent preparation is preferably 0.1 to 2% by weight, in particular 0.2 to 1% by weight.

Particularly preferred detergent preparations contain at least one amylase preparation and at least one mannanase preparation and at least one in addition to the pectinolytic enzyme preparation, in particular in addition to the pectylase preparation Protease preparation and at least one cellulase preparation and at least one lipase preparation.

The free-flowing detergent preparations contain less than 20% by weight of water. In view of the desired miniaturization of the detergent portion unit combined with high washing performance, it is preferable to further reduce this proportion by weight of water. Preference is therefore given to detergent preparations which, based on their total weight, contain less than 15% by weight of water, preferably 2 to 15% by weight and in particular 2 to 12% by weight of water.

Due to the entry of water through the raw materials used, it is generally not possible to achieve complete freedom from water in the detergent preparation. In addition to the water, the detergent preparations preferably contain organic solvent. The use of aqueous-organic solvent systems has proven to be particularly advantageous for the manufacturability and storability and is therefore preferred.

In a preferred embodiment, the detergent preparation contains, based on its total weight, 15 to 42% by weight, preferably 20 to 40% by weight and in particular 25 to 38% by weight of organic solvent.

Preferred organic solvents are selected from the group ethanol, n-propanol, i-propanol, butanols, glycol, propanediol, butanediol, methylpropanediol, glycerol, diglycol, propyldiglycol, butyldiglycol, hexylene glycol, ethylene glycol methyl ether, ethylene glycol ethyl ether, ethylene glycol propyl ether, ethylene glycol mono-n-butyl ether, Diethylene glycol methyl ether, diethylene glycol ethyl ether, propylene glycol methyl ether, propylene glycol ethyl ether, propylene glycol propyl ether, dipropylene glycol monomethyl ether, dipropylene glycol monoethyl ether, methoxytriglycol, ethoxytriglycol, butoxytriglycol, 1-butoxyethoxy-2-propanol, 3-methyl-3-methoxybutanol, propylene glycol t-butyl ether, di-n- octyl ether and mixtures thereof, preferably from the group of propanediol, glycerol, ethanol and mixtures thereof.

In addition to the components described above, the detergent preparations can contain other optional ingredients. A first group of preferred optional ingredients are the phosphonates.

The proportion by weight of the phosphonate in the total weight of the detergent preparation is preferably from 0.1 to 3% by weight and in particular from 0.2 to 1% by weight.

A hydroxyalkane and/or aminoalkane phosphonate is preferably used as the phosphonate compound. Among the hydroxyalkanephosphonates, 1-hydroxyethane-1,1-diphosphonate (HEDP) is of particular importance. Come as aminoalkane phosphonates preferably ethylenediaminetetramethylenephosphonate (EDTMP), diethylenetriaminepentamethylenephosphonate (DTPMP) and their higher homologues. The use of ethylenediaminetetramethylenephosphonate (EDTMP) and diethylenetriaminepentamethylenephosphonate (DTPMP) is very particularly preferred.

As a further optional component, a preferred detergent preparation comprises 0.2 to 4% by weight, preferably 0.5 to 3% by weight, of fragrance preparation.

In addition to the actual fragrances, the fragrance preparation includes, for example, solvents, solid carrier materials or stabilizers.

A fragrance is a chemical substance that stimulates the sense of smell. In order to be able to stimulate the sense of smell, the chemical substance should be at least partially airborne, i.e. the fragrance should be at least slightly volatile at 25°C. If the fragrance is now very volatile, the odor intensity then quickly fades away. With a lower volatility, however, the odor impression is more lasting, i.e. it does not disappear as quickly. In one embodiment, the fragrance therefore has a melting point in the range from -100°C to 100°C, preferably from -80°C to 80°C, more preferably from -20°C to 50°C, in particular from - 30°C to 20°C. In a further embodiment, the fragrance has a boiling point which is in the range from 25° C. to 400° C., preferably from 50° C. to 380° C., more preferably from 75° C. to 350° C., in particular from 100° C. to 330°C.

Overall, a chemical substance should not exceed a specific molecular mass in order to function as a fragrance, since the required volatility can no longer be guaranteed if the molecular mass is too high. In one embodiment, the fragrance has a molecular mass of 40 to 700 g/mol, more preferably 60 to 400 g/mol.

The smell of a fragrance is perceived as pleasant by most people and often corresponds to the smell of, for example, blossoms, fruits, spices, bark, resin, leaves, grass, moss and roots. Fragrances can also be used to mask unpleasant odors or to provide a non-smelling substance with a desired smell. Individual fragrance compounds, for example synthetic products of the ester, ether, aldehyde, ketone, alcohol and hydrocarbon type, can be used as fragrances.

Mixtures of different fragrances are preferably used, which together produce an appealing fragrance. Such a mixture of fragrances can also be referred to as a perfume or perfume oil. Perfume oils of this kind can also contain natural mixtures of fragrances, such as are obtainable from vegetable sources.

To prolong the fragrance effect, it has proven advantageous to encapsulate the fragrance. In a corresponding embodiment, at least part of the fragrance is used in encapsulated form (fragrance capsules), in particular in microcapsules. However, the entire fragrance can also be used in encapsulated form. The microcapsules can be water-soluble and/or water-insoluble microcapsules. For example, melamine-urea-formaldehyde microcapsules, melamine-formaldehyde microcapsules, urea-formaldehyde microcapsules or starch microcapsules can be used. "Pro-fragrance" refers to compounds that only release the actual fragrance after chemical conversion/cleavage, typically upon exposure to light or other environmental conditions such as pH, temperature, etc. Such compounds are often also referred to as fragrance storage substances or “pro-fragrance”.

The composition of some preferred free-flowing detergent preparations can be found in the following tables (data in % by weight based on the total weight of the preparation, unless stated otherwise). The detergent preparations are particularly preferably packaged as detergent portion units in which the detergent preparation is completely enclosed by a water-soluble film. formula 1 formula 2

The substance systems described above are not only suitable for ensuring simple manufacturability, good shelf life and cleaning performance, but also enable the realization of a product appearance that is attractive to the consumer. Detergent preparations which are transparent and consequently have a low degree of turbidity are referred to as optically attractive. Preferred detergent preparations therefore have a turbidity (HACH Turbidimeter 2100Q, 20° C., 10 ml cuvette) below 100 NTU, preferably below 50 NTU and in particular below 20 NTU.

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 Hach Company, Loveland, Colorado (USA) is used with the calibration substances StabICal Solution HACH (20 NTU), StabICal Solution HACH (100 NTU) and StabICal 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 visual advantages of the concentrated detergent preparations come into their own in particular in packaging materials, which in turn are transparent and allow a direct view of the detergent composition. In addition to transparent plastic bottles, transparent bags, in particular transparent water-soluble bags, are therefore particularly preferred for assembly and packaging.

1. i) eine erfindungsgemäße Waschmittelzubereitung
2. ii) einen wasserlöslichen Film, welcher die Waschmittelzubereitung vollständig umschließt.

A further subject matter of this application is therefore a detergent portion unit

1. i) a detergent preparation according to the invention
2. ii) a water-soluble film which completely encloses the detergent preparation.

The water-soluble film in which the 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 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 lies.

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 for use are marketed, inter alia, by the company MonoSol LLC, for example under the designation M8630, M8720, M8310, C8400 or M8900. For example, films with the name ^Solublon® PT, ^Solublon® GA, ^Solublon® KC or ^Solublon® KL from Aicello Chemical Europe GmbH or the films VF-HP from Kuraray are also suitable.

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 the preparation enclosed by the film material from decomposition or deactivation protect from 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 coefficients of friction, the surface of the water-soluble film of the detergent portion unit can optionally be powdered with a fine powder. Sodium aluminosilicate, silica, talc and amylose are examples of suitable powdering agents.

Preferred water-soluble films are suitable for processing in a thermoforming apparatus.

The volume of the detergent portion unit is preferably from 12 to 22 ml, in particular from 12 to 18 ml.

Detergent portion unit according to one of the previous points, wherein the detergent portion unit has one to four receiving chambers, preferably three or four receiving chambers.
