Description

[0001] The present invention relates to a surfactant- and enzyme-based detergent preparation. The application further relates to detergent portion units comprising this detergent preparation and to a method for washing textiles using the detergent preparation or the detergent portion unit.

[0002] The packaging and presentation of detergents and cleaning agents are subject to constantly changing requirements. For some time now, a major focus has been on convenient dosing by the consumer and simplifying the steps required for washing or cleaning. Pre-portioned detergents and cleaning agents, such as foil pouches with one or more compartments for solid or liquid detergents or cleaning agents, offer a technical solution.

[0003] A relevant trend in the production of these foil bags is their miniaturization. This development is driven not only by increased consumer acceptance due to simplified handling, but also by sustainability considerations, such as reduced transport volumes and costs, and the amount of packaging material used.

[0004] The increased concentration of modern detergents, especially modern liquid detergents, generally affects their optical and rheological properties, has an impact on the storage stability of these products, and can affect their cleaning performance, particularly if the high concentration of active ingredients leads to incompatibilities.

[0005] The European patent EP 2 254 979 B1 describes solid textile detergents with a small proportion of linear alkylbenzenesulfonic acid, which may contain pectinases in addition to other enzymes.

[0006] International patent application WO 2015 / 121133A1 describes liquid textile detergents with a high water content which, in addition to small amounts of linear alkylbenzenesulfonic acid, also contain pectinase.

[0007] DE 3635427 A1 teaches a phosphate-free detergent characterized by the presence of an enzyme with pectinase activity. DE 102017200139 A1 teaches detergent sheets in which the activation of the surfactants is controlled. US 2015 / 203796 A1 teaches detergents containing optical brighteners and color transfer inhibitors. WO 2016 / 155993 A1 teaches a detergent. US 10870821 B2 teaches a water-soluble detergent portion unit.

[0008] The application was based on the objective of providing visually appealing, concentrated, free-flowing detergent preparations that are easy and efficient to produce, have good storage properties, and are characterized, in particular, by good cleaning results. Specifically, the detergent preparation should be packaged in water-soluble portion sachets and be based predominantly on ingredients that can be produced, at least partially, from renewable raw materials.

[0009] The first subject matter of the application is a free-flowing detergent preparation containing, based on its total weight, a) 7 to 15 wt% anionic surfactant from the group of C 8-18 alkylbenzenesulfonates; b) 0.05 to 2 wt% of a preparation of a pectinolytic enzyme; c) 2 to 15 wt% water.

[0010] The detergent preparation is flowable under standard conditions (20°C, 1013 mbar).

[0011] A first essential component of the detergent preparation is C8-18-alkylbenzenesulfonate, which is present in the detergent preparation in proportions of 7 to 15% by weight. Preferred detergent preparations contain 9 to 15% by weight of C8-18-alkylbenzenesulfonate, based on their total weight.

[0012] Preferred C 8-18 alkylbenzenesulfonates have the general formula (I), in which R' and R" are independent H or alkyl and together contain 8 to 18, preferably 9 to 15 and in particular 9 to 13 C atoms, and Y +< denotes a monovalent cation or the nth part of an n-valent cation (in particular Na +< ).

[0013] In addition to the previously described C8-18 alkylbenzenesulfonates, the detergent preparation can contain further anionic surfactants. These further surfactants include, for example, alkyl ether sulfates, olefin sulfonates, C12-C18 alkanesulfonates, ester sulfonates, alk(en)yl sulfates, and mixtures thereof. However, it has been shown that the detergent preparation according to the invention achieves good washing results even without the use of these additional anionic surfactants. Therefore, for reasons of reduced complexity, miniaturization of the required detergent portion unit to the greatest extent possible, and an improved sustainability profile, it is preferred if the detergent preparation contains, based on its total weight, less than 10 wt%, preferably less than 6 wt%, and particularly less than 2 wt%, anionic surfactant from the group of alkyl ether sulfates.Furthermore, it may be advantageous if the detergent preparation, based on its total weight, contains, in addition to the anionic surfactant from the group of C 8-18 alkylbenzenesulfonates, less than 10 wt. %, preferably less than 6 wt. %, and in particular less than 2 wt. %, other anionic surfactant.

[0014] The use of fatty acids has proven advantageous for stability and cleaning performance. Preferred detergent formulations therefore contain 4 to 12 wt%, preferably 6 to 10 wt%, of fatty acids based on their total weight. Particularly preferred fatty acids are selected from the group consisting of caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, oleic acid, linoleic acid, and mixtures thereof. For the purposes of this application, the fatty acids are not classified as anionic surfactants.

[0015] The use of non-ionic surfactants is advantageous for the cleaning performance of detergent preparations. The weight fraction of non-ionic surfactants in the total weight of the detergent preparation is preferably 15 to 34 wt.%, preferably 18 to 30 wt.%.

[0016] Preferred non-ionic surfactants are selected 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, the C 13-15 alcohols with 5 EO, 7 EO or 8 EO, the C 13-15 oxo alcohols with 7 EO, the C 12-18 alcohols with 5 EO or 7 EO, in particular the C 12-18 fatty alcohols with 7 EO or the C 13-15 oxo alcohols with 7 EO.

[0017] With regard to the rheological properties of the detergent preparation, its processability and cleaning effect, it has proven advantageous to use non-ionic surfactant and anionic surfactant in a weight ratio of 2:1 to 3:2.

[0018] The second essential component of the detergent preparation is 0.05 to 2 wt.% of a preparation of a pectinolytic enzyme. In preferred embodiments, the weight fraction of this preparation in the total weight of the detergent preparation is 0.1 to 0.4 wt.%.

[0019] Within the scope of the present invention, the pectinolytic enzymes include enzymes designated as pectinase, pectate lyase, pectin esterase, pectin demethoxylase, pectin methoxylase, pectin methyl esterase, pectase, pectin methyl esterase, pectin pectyl hydrolase, pectin depolymerase, endopolygalacturonase, pectolase, pectin hydrolase, pectin polygalacturonase, endo-polygalacturonase, poly-α-1,4-galacturonide glycanohydrolase, endogalacturonase, endo-D-galacturonase, galacturan 1,4-α-galacturonidase, exopolygalacturonase, poly(galacturonate) hydrolase, exo-D-galacturonanase, and exo-D-galacturonanase. Exopoly-D-galacturonase, exopoly-α-galacturonosidase, exopolygalacturonosidase, or 25-exopolygalacturanosidase. The use of pectate lyases is particularly preferred.

[0020] Within the EC classification of enzymes, the numerical classification system for enzymes, pectinolytic enzymes belong specifically to the enzyme classes (Enzyme Commission numbers) EC 3.1.1.11, EC 3.2.1.15, EC 3.2.1.67, and EC 3.2.1.82. Consequently, they are part of the third of the six main enzyme classes, the 10 hydrolases (EC 3.1.1.1), specifically the glycosylases (EC 3.2.-.-) and, within these, the glycosidases (EC 3.2.1.-), i.e., enzymes that hydrolyze O- and / or S-glycosyl compounds. Pectinolytic enzymes are therefore particularly effective against residues on dishes containing pectic acid and / or other galacturonans, and catalyze their hydrolysis.

[0021] Pectate lyases within the meaning of the invention are enzymes that catalyze the non-hydrolytic cleavage of pectate via an endo-mechanism.

[0022] Examples of suitable pectinolytic enzymes are the enzymes and enzyme preparations available under the trade names Gamanase®, Pectinex AR®, X-Pect® or Pectaway® from Novozymes, under the trade names Rohapect UF®, Rohapect TPL®, Rohapect PTE100®, Rohapect MPE®, Rohapect MA plus HC, Rohapect DA12L®, Rohapect 10L®, Rohapect B1L® from AB Enzymes and under the trade name Pyrolase® from Diversa Corp., San Diego, CA, USA.

[0023] An enzyme preparation comprises, in addition to the actual enzyme protein, other components such as enzyme stabilizers, carrier materials, or fillers. The enzyme protein typically constitutes only a fraction of the total weight of the enzyme preparation. Preferably, enzyme preparations contain between 0.1 and 40 wt.%, preferably between 0.2 and 30 wt.%, more preferably between 0.4 and 20 wt.%, and most preferably between 0.8 and 10 wt.% of the enzyme protein. In such compositions, an enzyme stabilizer may be present in an amount of 0.05 to 35 wt.%, preferably 0.05 to 10 wt.%, based on the total weight in the enzyme composition.

[0024] Protein concentration can be determined using established methods, such as the BCA method (bicinchoninic acid; 2,2'-bicinolyl-4,4'-dicarboxylic acid) or the biuret method. The determination of the active protein concentration is carried out by titrating the active sites using a suitable irreversible inhibitor (for proteases, for example, phenylmethylsulfonylfluoride (PMSF)) and determining the residual activity.

[0025] Preferred preparations of pectinolytic enzymes, in particular pectate lyase preparations, contain, based on their total weight, a weight fraction of active protein of 0.1 and 40 wt.%, preferably of 0.2 and 30 wt.%.

[0026] In combination with the previously described preparations of pectinolytic enzymes, particularly in combination with pectate lyase preparations, further enzyme preparations are especially preferred in the detergent formulation. The weight fraction of these further enzyme preparations in the total weight of the detergent formulation is preferably 2 to 8 wt.% and particularly 3 to 6 wt.%.

[0027] It is preferred if the detergent preparation according to the invention contains, in addition to the preparation of pectinolytic enzyme, in particular in addition to the pectylase preparation, at least one enzyme preparation, preferably at least 3 enzyme preparations of enzymes from the group amylase, mannanase, protease, cellulase and lipase.

[0028] According to the invention, it is preferred if at least one protease is included as the enzyme. A protease is an enzyme that cleaves peptide bonds by hydrolysis. According to the invention, each of the enzymes from class EC 3.4 falls under this category (comprising each of the thirteen subclasses included therein). "Protease activity" is present according to the invention if the enzyme possesses proteolytic activity (EC 3.4). Various types of protease activity are known: The three main types are: trypsin-like, wherein cleavage of the amide substrate occurs along the amino acids Arg or Lys at P1; chymotrypsin-like, wherein cleavage occurs along the amino acids Arg or Lys at P1; and elastase-like, wherein cleavage of the amide substrate occurs along the amino acid Ala at P1.

[0029] Surprisingly, it was found that a protease of the alkaline protease type from Bacillus lentus DSM 5483, or a sufficiently similar protease (with respect to sequence identity) exhibiting several of these modifications in combination, is particularly suitable for use in the liquid detergent preparations according to the invention and is advantageously stabilized therein. The advantages of using this protease are therefore particularly evident with regard to washing performance and / or stability.

[0030] Particularly preferably, the detergent preparation according to the invention contains a protease of the alkaline protease type from Bacillus lentus DSM 5483 or a sufficiently similar protease (with respect to sequence identity) which has several of these modifications in combination,

[0031] The weight fraction of the protease preparation in the total weight of the detergent preparation is preferably 0.5 to 5 wt.%, in particular 1.0 to 4 wt.%.

[0032] As a further preferred optional component, the detergent preparations contain a cellulase preparation. Synonymous terms can be used for cellulases, in particular endoglucanase, endo-1,4-beta-glucanase, carboxymethylcellulase, 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.

[0033] Suitable cellulases (endoglucanases, EG) according to the invention include, for example, fungal endoglucanase (EG)-rich compositions offered by Novozymes under the trade name Celluzyme®. The products Endolase® and Carezyme®, also available from Novozymes, are based on the 50 kDa EG and 43 kDa EG from Humicola insolens DSM 1800, respectively. Other usable trade products from this company are Cellusoft®, Renozyme®, and Celluclean®. Also suitable are, for example, cellulases available from AB Enzymes, Finland, under the trade names Ecostone® and Biotouch®, which are at least partially based on the 20 kDa EG from Melanocarpus. Other cellulases from AB Enzymes are Econase® and Ecopulp®. Other suitable cellulases are from Bacillus sp. CBS 670.93 and CBS 669.93, with the one from Bacillus sp. CBS 670 being the most suitable.93 is available from Danisco / Genencor under the trade name Puradax®. Other usable commercial products from Danisco / Genencor are "Genencor detergent cellulase L" and IndiAge® Neutra.

[0034] The weight fraction of the cellulase preparation in the total weight of the detergent preparation is preferably 0.05 to 1 wt.%, in particular 0.1 to 0.5 wt.%.

[0035] According to the invention, it is further preferred if the detergent preparation according to the invention contains at least one lipase preparation. Lipases preferred according to the invention are selected from at least one enzyme of the group consisting of triacylglycerol lipase (EC 3.1.1.3), lipoprotein lipase (EC 3.1.1.34) and monoglyceride lipase (EC 3.1.1.23).

[0036] Preferred lipase preparations according to the invention are the commercial products marketed by Amano Pharmaceuticals under the names Lipase M-AP10®, Lipase LE®, and Lipase F® (also Lipase JV®). Lipase F® is, for example, naturally present in Rhizopus oryzae. Lipase M-AP10® is, for example, naturally present in Mucor javanicus.

[0037] A highly preferred lipase is commercially available under the trade name Lipex® from Novozymes (Denmark) and can be advantageously used in the detergent preparations according to the invention. Lipex® 100 L is particularly preferred.

[0038] Preferred detergent preparations are characterized in that they contain 0.01 to 1 wt.%, in particular 0.02 to 0.4 wt.%, of lipase preparation based on their total weight.

[0039] The detergent preparations according to the invention can additionally contain at least one mannanase preparation as an enzyme. A mannanase catalyzes the hydrolysis of 1,4-beta-D-mannosidic bonds in mannans, galactomannans, glucomannan, and galactoglucomannan. These mannanases are classified as EC 3.2.1.78 according to enzyme nomenclature.

[0040] Suitable mannaases are available under the trade name Mannaway ® from the company Novozymes.

[0041] The weight fraction of the mannanase preparation in the total weight of the detergent preparation is preferably 0.01 to 0.5 wt.%, in particular 0.02 to 0.2 wt.%.

[0042] The detergent preparations preferably contain at least one amylase, in particular an α-amylase. α-Amylases (EC 3.2.1.1) act as enzymes to hydrolyze internal α-1,4-glycosidic bonds of starch and starch-like polymers. Examples include α-amylases from Bacillus licheniformis, B. amyloliquefaciens, and B. stearothermophilus, as well as their improved formulations for use in detergents or cleaning agents. The enzyme from B. licheniformis is available from Novozymes under the trade name Termamyl® and from Genencor under the trade name Purastar® ST. Further developmental 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 of B.Amyloliquefaciens is marketed by Novozymes under the name BAN®<, and derivatives of the α-amylase from B. stearothermophilus are marketed under the names BSG®< and Novamyl®<, also by Novozymes. Examples of α-amylases from other organisms include the further developments of α-amylase from Aspergillus niger and A. oryzae, available from Novozymes under the trade names Fungamyl®<.

[0043] The weight fraction of the amylase preparation, in particular the α-amylase preparation, in the total weight of the detergent preparation is preferably 0.1 to 2 wt.%, in particular 0.2 to 1 wt.%.

[0044] Particularly preferred detergent preparations contain, in addition to the preparation of pectinolytic enzyme, in particular in addition to the pectylase preparation, at least one amylase preparation, at least one mannanase preparation, at least one protease preparation, at least one cellulase preparation, and at least one lipase preparation.

[0045] The free-flowing detergent preparations contain 2 to 15 wt% water. With regard to the desired miniaturization of the detergent portion while maintaining high washing performance, it is preferred to further reduce this water content by weight. Therefore, detergent preparations containing 2 to 12 wt% water by weight are preferred.

[0046] Due to the introduction of water from the raw materials used, achieving a completely water-free detergent formulation is generally not possible. In addition to water, the detergent formulations preferably contain an organic solvent. The use of aqueous-organic solvent systems has proven particularly advantageous for manufacturability and shelf life and is therefore preferred.

[0047] In a preferred embodiment, the detergent preparation contains, based on its total weight, 15 to 42 wt.%, preferably 20 to 40 wt.% and in particular 25 to 38 wt.% organic solvent.

[0048] Preferred organic solvents are selected from the group consisting of ethanol, n-propanol, i-propanol, butanols, glycol, propanediol, butanediol, methylpropanediol, glycerol, diglycylene, propyldiglycol, butyldiglycylene, 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 tert-butyl ether, di-n-octyl ether, and mixtures thereof, preferably from the group Propanediol, glycerin, ethanol and mixtures thereof.

[0049] In addition to the components described above, detergent preparations may contain further optional ingredients. Phosphonates form a first group of preferred optional ingredients.

[0050] The weight fraction of the phosphonate in the total weight of the detergent preparation is preferably 0.1 to 3 wt.% and particularly 0.2 to 1 wt.%.

[0051] A hydroxyalkane and / or aminoalkane phosphonate is preferably used as the phosphonate compound. Among the hydroxyalkane phosphonates, 1-hydroxyethane-1,1-diphosphonate (HEDP) is of particular importance. Ethylenediaminetetramethylenephosphonate (EDTMP), diethylenetriaminepentamethylenephosphonate (DTPMP), and their higher homologs are preferably suitable as aminoalkane phosphonates. The use of ethylenediaminetetramethylenephosphonate (EDTMP) and diethylenetriaminepentamethylenephosphonate (DTPMP) is especially preferred.

[0052] A preferred detergent preparation optionally comprises 0.2 to 4 wt.%, preferably 0.5 to 3 wt.% fragrance preparation.

[0053] In addition to the actual fragrance ingredients, the fragrance preparation includes, for example, solvents, solid carrier materials or stabilizers.

[0054] A fragrance is a chemical substance that stimulates the sense of smell. To stimulate the sense of smell, the chemical substance should be at least partially dispersible in the air, meaning the fragrance should be at least slightly volatile at 25°C. If the fragrance is highly volatile, the odor intensity dissipates quickly. With lower volatility, however, the odor impression is more lasting, meaning it does not disappear as quickly. In one embodiment, the fragrance therefore has a melting point in the range of -100°C to 100°C, preferably from -80°C to 80°C, even more preferably from -20°C to 50°C, and particularly from -30°C to 20°C. In another embodiment, the fragrance has a boiling point in the range of 25°C to 400°C, preferably 50°C to 380°C, more preferably 75°C to 350°C, and in particular 100°C to 330°C.

[0055] In general, a chemical substance should not exceed a certain molecular mass to function as a fragrance, as the required volatility cannot be guaranteed if the molecular mass is too high. In one embodiment, the fragrance has a molecular mass of 40 to 700 g / mol, or more preferably, 60 to 400 g / mol.

[0056] The scent of a fragrance is perceived as pleasant by most people and often corresponds to the smell of, for example, flowers, fruits, spices, bark, resin, leaves, grasses, mosses, and roots. Fragrances can therefore be used to mask unpleasant odors or to imbue an odorless substance with a desired scent. Individual odor compounds, such as synthetic products like esters, ethers, aldehydes, ketones, alcohols, and hydrocarbons, can be used as fragrances.

[0057] Preferably, mixtures of different fragrances are used, which together create an appealing scent. Such a mixture of fragrances can also be called perfume or perfume oil. These perfume oils can also contain natural fragrance mixtures, such as those available from plant sources.

[0058] To prolong the fragrance effect, encapsulating the fragrance has proven advantageous. In a corresponding embodiment, at least a portion of the fragrance is used in encapsulated form (fragrance capsules), particularly in microcapsules. However, the entire fragrance can also be used in encapsulated form. The microcapsules can be water-soluble and / or water-insoluble. For example, melamine-urea-formaldehyde microcapsules, melamine-formaldehyde microcapsules, urea-formaldehyde microcapsules, or starch microcapsules can be used. "Fragrance precursor" refers to compounds that release the actual fragrance only after chemical conversion / decomposition, typically through exposure to light or other environmental conditions such as pH, temperature, etc. Such compounds are also frequently referred to as fragrance precursors or "pro-fragrances."

[0059] The composition of some preferred free-flowing detergent preparations can be found in the following tables (values ​​in wt% based on the total weight of the preparation unless otherwise stated). The detergent preparations are particularly preferably packaged as single-dose units in which the detergent preparation is completely enclosed by a water-soluble film. formula 1 C 8-18 -Alkylbenzenesulfonate 9 to 15 Preparation of a pectinolytic enzyme, in particular pectate lyase preparation 0.1 to 0.4 Water 2 to 12 Misc ad 100 Formula 2 C 8-18 -Alkylbenzenesulfonate 9 to 15 Alkyl ether sulfate <2 Preparation of a pectinolytic enzyme, in particular pectate lyase preparation 0.1 to 0.4 Water 2 to 12 Misc ad 100 Formula 3 C 8-18 -Alkylbenzenesulfonate 9 to 15 non-ionic surfactant 28 to 30 Preparation of a pectinolytic enzyme, in particular pectate lyase preparation 0.1 to 0.4 Water 2 to 12 Misc ad 100 Formula 4 C 8-18 -Alkylbenzenesulfonate 9 to 15 Alkyl ether sulfate <2 non-ionic surfactant 28 to 30 Preparation of a pectinolytic enzyme, in particular pectate lyase preparation 0.1 to 0.4 Water 2 to 12 Misc ad 100 Formula 5 C 8-18 -Alkylbenzenesulfonate 9 to 15 Alkyl ether sulfate <2 fatty acid 6 to 10 non-ionic surfactant 28 to 30 Preparation of a pectinolytic enzyme, in particular pectate lyase preparation 0.1 to 0.4 Water 2 to 12 Misc ad 100 Formula 6 C 8-18 -Alkylbenzenesulfonate 9 to 15 Alkyl ether sulfate <2 Preparation of a pectinolytic enzyme, in particular pectate lyase preparation 0.1 to 0.4 Enzyme preparations containing protease, amylase, cellulase, mannanase, and lipase 3 to 6 Water 2 to 12 Misc ad 100 Formula 7 C 8-18 -Alkylbenzenesulfonate 9 to 15 Alkyl ether sulfate <2 non-ionic surfactant 28 to 30 Preparation of a pectinolytic enzyme, in particular pectate lyase preparation 0.1 to 0.4 Enzyme preparations containing protease, amylase, cellulase, mannanase, and lipase 3 to 6 Water 2 to 12 Misc ad 100 Formula 8 C 8-18 -Alkylbenzenesulfonate 9 to 15 Alkyl ether sulfate <2 fatty acid 6 to 10 non-ionic surfactant 28 to 30 Preparation of a pectinolytic enzyme, in particular pectate lyase preparation 0.1 to 0.4 Enzyme preparations containing protease, amylase, cellulase, mannanase, and lipase 3 to 6 Water 2 to 12 Misc ad 100 Formula 9 C 8-18 -Alkylbenzenesulfonate 9 to 15 Preparation of a pectinolytic enzyme, in particular pectate lyase preparation 0.1 to 0.4 Water 2 to 12 organic solvent 25 to 38 Misc ad 100 Formula 10 C 8-18 -Alkylbenzenesulfonate 9 to 15 Alkyl ether sulfate <2 Preparation of a pectinolytic enzyme, in particular pectate lyase preparation 0.1 to 0.4 Water 2 to 12 organic solvent 25 to 38 Misc ad 100 Formula 11 C 8-18 -Alkylbenzenesulfonate 9 to 15 non-ionic surfactant 28 to 30 Preparation of a pectinolytic enzyme, in particular pectate lyase preparation 0.1 to 0.4 Water 2 to 12 organic solvent 25 to 38 Misc ad 100 Formula 12 C 8-18 -Alkylbenzenesulfonate 9 to 15 Alkyl ether sulfate <2 non-ionic surfactant 28 to 30 Preparation of a pectinolytic enzyme, in particular pectate lyase preparation 0.1 to 0.4 Water 2 to 12 organic solvent 25 to 38 Misc ad 100 Formula 13 C 8-18 -Alkylbenzenesulfonate 9 to 15 Alkyl ether sulfate <2 fatty acid 6 to 10 non-ionic surfactant 28 to 30 Preparation of a pectinolytic enzyme, in particular pectate lyase preparation 0.1 to 0.4 Water 2 to 12 organic solvent 25 to 38 Misc ad 100 Formula 14 C 8-18 -Alkylbenzenesulfonate 9 to 15 Alkyl ether sulfate <2 Preparation of a pectinolytic enzyme, in particular pectate lyase preparation 0.1 to 0.4 Enzyme preparations containing protease, amylase, cellulase, mannanase, and lipase 3 to 6 Water 2 to 12 organic solvent 25 to 38 Misc ad 100 Formula 15 C 8-18 -Alkylbenzenesulfonate 9 to 15 Alkyl ether sulfate <2 non-ionic surfactant 28 to 30 Preparation of a pectinolytic enzyme, in particular pectate lyase preparation 0.1 to 0.4 Enzyme preparations containing protease, amylase, cellulase, mannanase, and lipase 3 to 6 Water 2 to 12 organic solvent 25 to 38 Misc ad 100 Formula 16 C 8-18 -Alkylbenzenesulfonate 9 to 15 Alkyl ether sulfate <2 fatty acid 6 to 10 non-ionic surfactant 28 to 30 Preparation of a pectinolytic enzyme, in particular pectate lyase preparation 0.1 to 0.4 Enzyme preparations containing protease, amylase, cellulase, mannanase, and lipase 3 to 6 Water 2 to 12 organic solvent 25 to 38 Misc ad 100

[0060] The material systems described above are not only suitable for ensuring ease of manufacture, good shelf life, and cleaning performance, but also enable the realization of a product appearance that is attractive to consumers. Washing detergent preparations that are transparent and consequently exhibit low turbidity are considered visually appealing. Preferred washing detergent preparations therefore have a turbidity (HACH turbidimeter 2100Q, 20°C, 10 ml cuvette) below 100 NTU, preferably below 50 NTU, and particularly below 20 NTU.

[0061] The Nephelometric Turbidity Unit (NTU) is frequently used as a measure of transparency. It is a unit used, for example, in water treatment for measuring turbidity in liquids. It is the unit of turbidity measured with a calibrated nephelometer. High NTU values ​​indicate turbid compositions, while low values ​​indicate clear compositions.

[0062] The HACH Turbidimeter 2100Q from 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 Hach Company. The measurement is performed in a 10 ml measuring cuvette with a cap, filled with the composition to be analyzed, and the measurement is carried out at 20 °C.

[0063] At an NTU value (at 20°C) of 60 or more, molded bodies exhibit a perceptible opacity, visible to the naked eye, in accordance with the invention.

[0064] The visual advantages of concentrated detergent preparations are particularly evident in packaging materials that are transparent and allow a direct view of the detergent composition. Therefore, in addition to transparent plastic bottles, transparent pouches, especially transparent water-soluble pouches, are preferred for packaging and assembly.

[0065] The material systems described above are not only suitable for ensuring ease of manufacture, good shelf life, and cleaning performance, but also enable the realization of a product appearance that is attractive to consumers. Washing detergent preparations that are transparent and consequently exhibit low turbidity are considered visually appealing. Preferred washing detergent preparations therefore have a turbidity (HACH turbidimeter 2100Q, 20°C, 10 ml cuvette) below 100 NTU, preferably below 50 NTU, and particularly below 20 NTU.

[0066] The Nephelometric Turbidity Unit (NTU) is frequently used as a measure of transparency. It is a unit used, for example, in water treatment for measuring turbidity in liquids. It is the unit of turbidity measured with a calibrated nephelometer. High NTU values ​​indicate turbid compositions, while low values ​​indicate clear compositions.

[0067] The HACH Turbidimeter 2100Q from 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 Hach Company. The measurement is performed in a 10 ml measuring cuvette with a cap, filled with the composition to be analyzed, and the measurement is carried out at 20 °C.

[0068] At an NTU value (at 20°C) of 60 or more, molded bodies exhibit a perceptible opacity, visible to the naked eye, in accordance with the invention.

[0069] The visual advantages of concentrated detergent preparations are particularly evident in packaging materials that are transparent and allow a direct view of the detergent composition. Therefore, in addition to transparent plastic bottles, transparent pouches, especially transparent water-soluble pouches, are preferred for packaging and assembly.

[0070] Another subject of this application is therefore a detergent portion unit comprising i) a detergent preparation according to the invention ii) a water-soluble film which completely encloses the detergent preparation.

[0071] The water-soluble film in which the detergent preparation is packaged can comprise one or more structurally different water-soluble polymers. Particularly suitable water-soluble polymers include polymers from the group of (optionally acetalized) polyvinyl alcohols (PVALs) and their copolymers.

[0072] Water-soluble films are preferably based on a polyvinyl alcohol or a polyvinyl alcohol copolymer whose molecular weight is in the range of 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 particularly from 40,000 to 80,000 gmol -1< .

[0073] The production of polyvinyl alcohols and polyvinyl alcohol copolymers generally involves the hydrolysis of intermediate polyvinyl acetates. 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 especially 82 to 88 mol%.

[0074] Preferred polyvinyl alcohol copolymers comprise, in addition to vinyl alcohol, an ethylene-unsaturated carboxylic acid, its salt, or its ester. Particularly preferred are such polyvinyl alcohol copolymers containing, besides vinyl alcohol, sulfonic acids such as 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS), acrylic acid, methacrylic acid, acrylic acid esters, methacrylic acid esters, or mixtures thereof; among the esters, C1-4 alkyl esters or hydroxyalkyl esters are preferred. Further monomers include ethylene-unsaturated dicarboxylic acids, for example, itaconic acid, maleic acid, fumaric acid, and mixtures thereof.

[0075] Suitable water-soluble films for use are distributed by companies such as MonoSol LLC, for example under the designations M8630, M8720, M8310, C8400, or M8900. Films such as Solublon®< PT, Solublon®< GA, Solublon®< KC, or Solublon®< KL from Aicello Chemical Europe GmbH, or the VF-HP films from Kuraray, are also suitable.

[0076] The water-soluble films may contain additional active ingredients or fillers, as well as plasticizers and / or solvents, especially water.

[0077] Other active ingredients include, for example, materials that protect the ingredients of the preparation, enclosed by the film material, from degradation or deactivation by light exposure. Antioxidants, UV absorbers, and fluorescent dyes have proven particularly suitable for this purpose.

[0078] Examples of plasticizers that can be used include glycerin, ethylene glycol, diethylene glycol, propanediol, 2-methyl-1,3-propanediol, sorbitol or mixtures thereof.

[0079] To reduce its coefficient of friction, the surface of the water-soluble film of the detergent portion unit can optionally be dusted with fine powder. Sodium aluminosilicate, silicon dioxide, talc, and amylose are examples of suitable powders.

[0080] Preferred water-soluble films are suitable for processing in a thermoforming apparatus.

[0081] The volume of the detergent portion unit is preferably from 12 to 22 ml, in particular from 12 to 18 ml.

[0082] Detergent portioning unit according to one of the preceding points, wherein the detergent portioning unit has one to four receiving chambers, preferably three or four receiving chambers.

[0083] Another subject of the application is a method for textile cleaning in which a previously described detergent preparation or detergent portion unit is introduced into the washing liquor of a textile washing machine.

[0084] In preferred process variants, the detergent preparation or the detergent portion unit is dosed directly into the drum or into the detergent dispenser drawer of the textile washing machine.

[0085] The machine washing process preferably takes place at temperatures of 20°C to 60°C, preferably from 30°C to 45°C. Examples

[0086] Textile fabrics were soiled with standardized materials and subsequently washed at 40°C in liquors containing 1 g / l of a detergent class V1 to V3 or E1. After washing, the textiles were dried. The brightness values ​​of the cleaned textiles were determined. The values ​​given are averages from five washing trials.
