Concentrated detergent preparation with improved properties

Description

[0001] The present invention relates to a detergent portion unit based on a highly concentrated surfactant detergent preparation, in particular a detergent preparation containing 1,2-octanediol. The application further relates to methods for washing textiles using 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 application was based on the task of providing visually appealing, concentrated, free-flowing detergent preparations that are easy and efficient to produce, have good shelf life, and are characterized in particular by good cleaning results, especially improved stain removal. Furthermore, the detergent preparation should be packaged in water-soluble portion sachets.

[0006] EP 0817881 B1 and EP 0227195 A2 describe cleaning compositions for stain removal which contain 1,2-octanediol in addition to other ingredients. Detergent preparations are also known from EP 3974506 A1, WO 2022 / 063499 A1 and WO 2017 / 216215.

[0007] Surprisingly, it was found that the washing performance of specific low-water and high-active-ingredient liquid detergents can be improved by the addition of 1,2-octanediol.

[0008] The first subject of the application is a detergent portion unit, comprising a) a free-flowing detergent preparation containing, based on its total weight: a1) 20 to 80 wt.% surfactant; a2) 2 to 15 wt.% fatty acid; a3) 0.2 to 10 wt.% washing-active polymer; a4) 0.2 to 7 wt.% enzyme preparation; a5) 1,2-octanediol; a6) 5 to 30 wt.% of the 1,2-octanediol, various organic solvents; a7) less than 20 wt.% water; b) a water-soluble coating completely enclosing the free-flowing detergent preparation. wherein the detergent preparation contains, based on its total weight, 0.0001 to 9 wt.%, preferably 0.0005 to 7 wt.%, in particular 0.01 to 5.5 wt.% 1,2-octanediol.

[0009] The detergent preparation is flowable under standard conditions (20°C, 1013 mbar).

[0010] The detergent preparation contains 20 to 80 wt% surfactant as its first essential component. Preferred detergent preparations contain 30 to 75 wt%, preferably 40 to 70 wt%, surfactant based on their total weight.

[0011] The group of surfactants includes nonionic, anionic, cationic, and amphoteric surfactants. The compositions according to the invention can comprise one or more of these surfactants. Particularly preferred compositions contain surfactants from the group of anionic and nonionic surfactants.

[0012] Preferred detergent preparations contain, based on their total weight, 15 to 50 wt.%, preferably 15 to 40 wt.% anionic surfactant.

[0013] The anionic surfactant is preferably selected from the group comprising C9-C13 alkylbenzenesulfonates, olefin sulfonates, C12-C18 alkanesulfonates, ester sulfonates, alk(en)yl sulfates, fatty alcohol ether sulfates, and mixtures thereof. Compositions comprising C9-C13 alkylbenzenesulfonates and fatty alcohol ether sulfates as the anionic surfactant exhibit particularly good dispersing properties. Suitable sulfonate-type surfactants include preferably C9-C13 alkylbenzenesulfonates, olefin sulfonates (i.e., mixtures of alkene and hydroxyalkanesulfonates), and disulfonates, such as those obtained, for example, from C12-C18 monoolefins with terminal or internal double bonds by sulfonation with gaseous sulfur trioxide and subsequent alkaline or acidic hydrolysis of the sulfonation products.Also suitable are C 12 -C 18 -alkanesulfonates and the esters of α-sulfofaticial acids (estersulfonates), for example the α-sulfonated methyl esters of hydrogenated coconut, palm kernel or tallow fatty acids.

[0014] The anionic surfactant is preferably selected from the group of C 8-18 alkylbenzenesulfonic acids.

[0015] It is particularly preferred if the composition contains at least one anionic surfactant of 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 +< denote a monovalent cation or the nth part of an n-valent cation (in particular monoethanolamine).

[0016] The group of alkyl ether sulfates includes fatty alcohol ether sulfates, for example, the sulfuric acid monoesters of straight-chain or branched C7-C21 alcohols ethoxylated with 1 to 6 mol of ethylene oxide, such as 2-methyl-branched C9-C11 alcohols with an average of 3.5 mol of ethylene oxide (EO) or C12-C18 fatty alcohols with 1 to 4 EO. Alkyl ether sulfates with the formula (II) R1< -O-(AO)n-SO3-< X+< (II) are preferred.

[0017] In this formula (II), R<1> represents a linear or branched, substituted or unsubstituted alkyl group, preferably a linear, unsubstituted alkyl group, and particularly preferably a fatty alcohol group. Preferred R<1> groups of formula (II) are selected from decyl, undecyl, dodecyl, tridecyl, tetradecyl, pentadecyl, hexadecyl, heptadecyl, octadecyl, nonadecyl, and eicosyl groups and mixtures thereof, with those having an even number of carbon atoms being preferred. Particularly preferred R<1> groups of formula (II) are derived from fatty alcohols with 12 to 18 carbon atoms, for example, coconut fatty alcohol, tallow fatty alcohol, lauryl, myristyl, cetyl, or stearyl alcohol, or from oxo alcohols with 10 to 20 carbon atoms.

[0018] In formula (II), AO represents an ethylene oxide (EO) or propylene oxide (PO) group, preferably an ethylene oxide group. The subscript n in formula (I) is an integer from 1 to 50, preferably from 1 to 20, and particularly from 2 to 10. n 2, 3, 4, 5, 6, 7, or 8 is especially preferred. X is a monovalent cation or the nth part of an n-valent cation, preferably the alkali metal ions, including Na⁺ or K⁺, with Na⁺ being most preferred. Further cations X⁺ can be selected from NH₄⁺, ½ Zn²⁺, ½ Mg²⁺, ½ Ca²⁺, ½ Mn²⁺, and mixtures thereof, as well as primary and secondary amines, particularly monoethanolamine.

[0019] In another preferred embodiment, the detergent preparation contains an anionic surfactant from the group of alkyl ethersulfonic acids.

[0020] Particularly preferred compositions contain an alkyl ether sulfate selected from fatty alcohol ether sulfates of formula (III) with k = 11 to 19, n = 2, 3, 4, 5, 6, 7, or 8. Particularly preferred representatives are Na fatty alcohol ether sulfates with 12 to 18 carbon atoms and 2 EOs (k = 11 to 13, n = 2 in Formula III). The stated degree of ethoxylation represents a statistical average, which may be a whole number or a fraction for a specific product. The stated degrees of alkoxylation represent statistical averages, which may be a whole number or a fraction for a specific product. Preferred alkoxylates / ethoxylates exhibit a narrow range of homologs (narrow range ethoxylates, NRE).

[0021] In summary, preferred detergent preparations contain, based on their total weight, 12 to 30 wt.%, preferably 15 to 28 wt.% and in particular 18 to 26 wt.% anionic surfactant from the group of C 8-18 alkylbenzenesulfonates and alkyl ether sulfates, preferably from the group of C 8-18 alkylbenzenesulfonates.

[0022] As an alternative to anionic surfactants or in combination with anionic surfactants, preferred detergent preparations contain non-ionic surfactant, preferably 15 to 50 wt.%, preferably 15 to 40 wt.% non-ionic surfactant.

[0023] The use of a non-ionic surfactant from the group of alkyl ethoxylates is particularly preferred, wherein preferred alkyl ethoxylates are selected from the group of ethoxylated primary C 6-18 alcohols, preferably the ethoxylated primary C 6-18 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.

[0024] In summary, preferred detergent preparations contain a non-ionic surfactant from the group of ethoxylated primary C 6-18 alcohols, preferably the ethoxylated primary C 6-18 alcohols with a degree of alkoxylation ≥ 2, 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.

[0025] With regard to the rheological properties of the detergent preparation, its processability and cleaning effect, it has proven advantageous to use anionic surfactant and nonionic surfactant in a weight ratio of 3:1 to 1:3, preferably 2:1 to 1:2 and particularly 3:2 to 2:3.

[0026] The second essential component of the detergent preparation is fatty acid. Preferred detergent preparations therefore contain, based on their total weight, 3 to 12 wt%, preferably 5 to 10 wt%, fatty acid. 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.

[0027] In addition to surfactants and fatty acids, detergent preparations according to the invention contain washing-active polymers. Their weight fraction in the total weight of the detergent preparation is 0.2 to 10 wt.%. Due to their washing performance, preferred detergent preparations contain, based on their total weight, 1 to 10 wt.%, preferably 4 to 10 wt.%, washing-active polymer.

[0028] A first group of preferred washing-active polymers are the polyalkoxylated polyalkylenemines, which are obtainable by reacting polyalkylenemines with alkylene oxides.

[0029] The polyalkoxylated polyalkylenemine is a polymer with a polyalkylenemine backbone bearing polyalkoxy groups at the nitrogen atoms. It preferably has a weight-average molecular weight (Mw) in the range of 5000 g / mol to 60000 g / mol, particularly from 10000 g / mol to 22500 g / mol. The polyalkylenemine has primary amino groups at its ends and preferably both secondary and tertiary amino groups in its interior; optionally, it may also have only secondary amino groups in its interior, resulting in a linear rather than a branched-chain polyalkylenemine. The ratio of primary to secondary amino groups in the polyalkylenemine is preferably in the range of 1:0.5 to 1:1.5, particularly in the range of 1:0.7 to 1:1. The ratio of primary to tertiary amino groups in the polyalkylenemine is preferably in the range of 1:0.2 to 1:1, particularly in the range of 1:0.5 to 1:0.8.Preferably, the polyalkylenemine has a weight-average molecular weight in the range of 500 g / mol to 50,000 g / mol, particularly from 550 g / mol to 2,000 g / mol. The nitrogen atoms in the polyalkylenemine are preferably separated from one another by alkylene groups with 2 to 12 carbon atoms, particularly 2 to 6 carbon atoms, whereby not all alkylene groups need to have the same number of carbon atoms. Ethylene groups, 1,2-propylene groups, 1,3-propylene groups, and mixtures thereof are particularly preferred. The primary amino groups in the polyalkylenemine can bear 1 or 2 polyalkoxy groups, and the secondary amino groups can bear 1 polyalkoxy group, whereby not every amino group needs to be alkoxy substituted. The average number of alkoxy groups per primary and secondary amino function in the polyalkoxylated polyalkyenimine is preferably 5 to 100, particularly 10 to 50.The alkoxy groups in the polyalkoxylated polyalkylenemine are preferably ethoxy, propoxy, or butoxy groups, or mixtures thereof. Polyethoxylated polyethyleneimines are particularly preferred. The polyalkoxylated polyalkylenemines are accessible by reacting the polyalkylenemines with the alkoxy groups of corresponding epoxides. Optionally, the terminal OH function of at least some of the polyalkoxy substituents can be replaced by an alkyl ether function with 1 to 10, and in particular 1 to 3, carbon atoms.

[0030] The polyalkoxylated amines with a weight-average molecular weight Mw in the range of 600 g / mol to 10000 g / mol, which are obtainable by reacting ammonia or primary alkyl or hydroxyalkyl amines having a molecular weight below 200 g / mol with alkylene oxides, form a second group of preferred washing-active polymers.

[0031] Preferred polyalkoxylated amines have a weight-average molecular weight Mw in the range of 1300 g / mol to 6000 g / mol, particularly from 1400 g / mol to 4500 g / mol. (The mean molecular weights given here and subsequently, if applicable, for other polymers, are weight-average molecular weights Mw, which can generally be determined by gel permeation chromatography using an RI detector, the measurement being expediently carried out against an external standard.)) For their preparation, one can start in a known manner from ammonia, a monoalkylamine, a monoalkyl monoalkanolamine or a monoalkyl dialkanolamine or a mono-, di- or trialanolamine, for example triethanolamine, methyl-, ethyl-, propyl- and isopropyl-diethanolamine, methyl-, ethyl-, propyl- and isopropyl-diisopropanolamine, tripropanolamine, triisopropanolamine, N,N-di-(2-hydroxyethyl)cyclohexylamine, N,N-di-(2-hydroxypropyl)cyclohexylamine, n-butylamine, n-hexylamine, n-octylamine, isopropylamine, sec-butylamine, tert-butylamine, cyclohexylamine, 2-ethylhexylamine, 2-phenylethylamine and mixtures thereof, which is combined with an alkylene oxide, in particular selected from the group consisting of ethylene oxide, propylene oxide, Butylene oxide and mixtures thereof, is reacted, in particular with a mixture containing propylene oxide and preferably ethylene oxide, especially preferably with propylene oxide.The polyalkoxylated amines obtained in this way can have block or random structures. A polyalkoxylated amine obtainable by propoxylation of triethanolamine is particularly preferred, preferably with each of its three side arms having a length of 15 propylene oxide units. A polyalkoxylated amine obtainable by propoxylation of triisopropanolamine is also preferred, preferably with each of its three side arms having a length of 15 propylene oxide units. Polyalkoxylated monoalkylamines with a linear, branched, or cyclic alkyl group are also suitable, wherein alkoxylation is performed with an alkylene oxide selected from the group consisting of ethylene oxide, propylene oxide, butylene oxide, and mixtures thereof, preferably with a mixture containing propylene oxide, and particularly preferably with propylene oxide.A polyalkoxylated amine obtainable by propoxylation of tert-butylamine is also preferred, preferably with a length of the two side arms of 12 propylene oxide units each.

[0034] A third group of preferred washing-active polymers are the alcohol polyalkoxylates with a weight-average molecular weight Mw in the range of 600 g / mol to 10000 g / mol, which are obtainable by reacting di- or triols with primary and / or secondary OH groups, having a molecular weight Mw in the range of 60 g / mol to 200 g / mol, with alkylene oxides.

[0035] Preferred alcohol polyalkoxylates have a weight-average molecular weight Mw in the range of 1300 g / mol to 6000 g / mol, particularly from 1400 g / mol to 4500 g / mol. They can be prepared in a known manner starting with a diol or triol having a molecular weight preferably in the range of 70 g / mol to 150 g / mol, which is reacted, particularly under alkaline conditions, with an alkylene oxide, especially selected from the group consisting of ethylene oxide, propylene oxide, butylene oxide, and mixtures thereof, particularly with a mixture containing propylene oxide and preferably ethylene oxide, and most preferably with propylene oxide.

[0036] Preferred alcohol polyalkoxylates satisfy the general formula (V) in which R stands for a linear, optionally branched or optionally cyclic alkyl group with 1 to 12 C atoms or a group -(CH 2 CHR'O) n" -(CH 2 CHR"O) m" -H, R' and R" independently represent H, CH 3 or CH 2 CH 3, n, n' and n" independently represent numbers from 0 to 30, preferably from 0 to 10 and in particular from 0 to 5, and m, m` and m" independently represent numbers from 0 to 30, preferably from 5 to 20 and in particular from 12 to 16, provided that the sum n + n` + n" + m + m' + m" is at least 14, preferably in the range of 18 to 100 and in particular in the range of 20 to 70.

[0037] The use of an alcohol polyalkoxylate from the group of polypropylene glycols is particularly preferred.

[0038] Finally, a fourth group of preferred washing-active polymers comprises the ethylene oxide-propylene oxide-ethylene oxide triblock copolymers, wherein the copolymer includes a first EO block, a second EO block and a PO block, with the first EO block and the second EO block being linked to the PO block.

[0039] The ethylene oxide-propylene oxide-ethylene oxide (EO / PO / EO) triblock copolymer preferably has an average propylene oxide chain length between 15 and 70, more preferably between 20 and 60, more preferably between 25 and 50, even more preferably between 25 and 40, most preferably between 25 and 35 propylene oxide units.

[0042] The ethylene oxide-propylene oxide-ethylene oxide triblock copolymer comprises, on average, between 10 wt.% and 90 wt.%, preferably between 20 wt.% and 70 wt.%, most preferably between 30 wt.% and 50 wt.% of the copolymer the combined ethylene oxide blocks, wherein, more preferably, the total ethylene oxide content is distributed over the two ethylene oxide blocks such that each ethylene oxide block comprises, on average, between 40% and 60%, preferably between 45% and 55%, even more preferably between 48% and 52%, most preferably 50% of the total number of ethylene oxide units, wherein the percentage of both ethylene oxide blocks together constitutes 100% of the ethylene oxide units present.

[0043] Preferred detergent preparations contain an ethylene oxide-propylene oxide-ethylene oxide triblock copolymer with an average molecular weight between 2500 and 3000, an average propylene oxide content between 25 and 35 propylene oxide units, and an average ethylene oxide content between 10 and 15 ethylene oxide units per ethylene oxide block.

[0044] The fourth component of the detergent preparation according to the invention is the enzyme preparation with a weight fraction of 0.2 to 7 wt.%. Preferred detergent preparations contain, based on their total weight, 0.4 to 6 wt.%, preferably 0.5 to 5 wt.% enzyme preparation.

[0045] 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 between 0.05 and 10 wt.%, based on the total weight in the enzyme composition.

[0046] 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.

[0047] It is preferred if the detergent preparation contains at least one enzyme preparation, preferably at least three enzyme preparations of enzymes from the group amylase, protease, cellulase and mannanase.

[0048] 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®<.

[0049] The weight fraction of the amylase preparation, in particular the amylase preparation, in the total weight of the detergent preparation is preferably 0.1 to 2 wt.%, in particular 0.2 to 1 wt.%.

[0050] According to the invention, it is preferred if the detergent preparation contains at least one protease as an 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 one of the hydrophobic amino acids at P1; and elastase-like, wherein cleavage of the amide substrate occurs along the Ala at P1.

[0051] 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 detergent preparations according to the invention and is advantageously stabilized therein. The advantages of using this protease thus arise particularly with regard to washing performance and / or stability.

[0052] 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,

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.

[0055] 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.

[0056] The weight fraction of the cellulase preparation in the total weight of the detergent preparation is preferably 0.01 to 1 wt.%, preferably 0.05 to 0.3 wt.%.

[0057] The detergent preparation preferably contains 0.01 to 1 wt.%, preferably 0.02 to 0.3 wt.% of a mannanase preparation.

[0058] 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.

[0059] According to the invention, it is further preferred if the detergent preparation 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).

[0060] 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.

[0061] 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.

[0062] Preferred detergent preparations are characterized in that they contain 0.01 to 1 wt.%, in particular 0.05 to 0.3 wt.%, of lipase preparation based on their total weight.

[0063] Preferred detergent preparations contain, as an optional component, based on their total weight, 0.05 to 2 wt.%, preferably 0.1 to 0.4 wt.%, of a preparation of a pectinolytic enzyme.

Exopoly-D-galacturonase, exopoly-α-galacturonosidase, exopolygalacturonosidase, or 25-exopolygalacturanosidase. The use of pectate lyases is particularly preferred.

[0065] 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.

[0066] Pectate lyases within the meaning of the invention are enzymes that catalyze the non-hydrolytic cleavage of pectate via an endo-mechanism.

[0067] 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.

[0068] The other features of the detergent preparation are the 1,2-octanediol, the organic solvents different from the 1,2-octanediol and the water also used.

[0069] Detergent preparations according to the invention contain, based on their total weight, 0.0001 to 9 wt.%, preferably 0.0005 to 7 wt.%, in particular 0.01 to 5.5 wt.% 1,2-octanediol.

[0070] The weight fraction of the organic solvent other than 1,2-octanediol in the total weight of the detergent preparation is 8 to 30 wt.%, preferably 12 to 25 wt.%.

[0071] The group of preferred organic solvents other than 1,2-octanediol includes, in particular, ethanol, n-propanol, i-propanol, butanols, glycol, propanediol, butanediol, methylpropanediol, glycerin, diglycyl, propyldiglycol, butyldiglycyl, 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 the organic solvents. Amines, in particular monoethanolamine, and mixtures thereof, preferably organic solvents from the group consisting of propanediol, glycerin, ethanol, monoethanolamine and mixtures thereof.

[0072] Preferred detergent preparations have a water content of 4 to 18 wt.%, in particular 5 to 12 wt.% water, based on their total weight.

[0073] The detergent preparation contains a phosphonate as a preferred optional ingredient.

[0074] 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.%.

[0075] The phosphonate compound is preferably selected from the group of hydroxyalkane and / or aminoalkane phosphonates, preferably from the group of aminoalkane phosphonates and in particular from the group of ethylenediaminetetramethylenephosphonate (EDTMP) and diethylenetriaminepentamethylenephosphonate (DTPMP), in particular from the group of diethylenetriaminepentamethylenephosphonate (DTPMP).

[0076] A preferred detergent preparation optionally comprises 0.2 to 4 wt.%, preferably 0.5 to 3 wt.% fragrance preparation.

[0077] In addition to the actual fragrance ingredients, the fragrance preparation includes, for example, solvents, solid carrier materials or stabilizers.

[0078] 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.

[0079] 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.

[0080] 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 odorant compounds, such as synthetic products like esters, ethers, aldehydes, ketones, alcohols, and hydrocarbons, can be used as fragrances.

[0081] 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.

[0082] 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."

[0084] 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. For example, detergent preparations that are transparent and consequently exhibit low turbidity are perceived as visually appealing. Preferred 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. At an NTU value (at 20°C) of 60 or more, molded bodies exhibit a perceptible turbidity, visible to the naked eye, in accordance with the invention.

[0085] 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 water-soluble transparent pouches, are preferred for packaging and assembly.

[0086] Preferably, the water-soluble coating comprises or consists of a film material. The film material 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.

[0087] 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< .

[0088] 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%.

[0089] 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 suitable monomers include ethylene-unsaturated dicarboxylic acids, for example, itaconic acid, maleic acid, fumaric acid, and mixtures thereof.

[0090] 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.

[0091] The water-soluble films may contain additional active ingredients or fillers, as well as plasticizers and / or solvents, especially water.

[0092] 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.

[0093] Examples of plasticizers that can be used include glycerin, ethylene glycol, diethylene glycol, propanediol, 2-methyl-1,3-propanediol, sorbitol or mixtures thereof.

[0094] 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.

[0095] Preferred water-soluble films are suitable for processing in a thermoforming apparatus.

[0096] The volume of the detergent portion unit is preferably from 12 to 28 ml, in particular from 12 to 26 ml.

[0097] Preferred detergent portion units have one to four receiving chambers, preferably three or four. In detergent portion units with two or more receiving chambers, preferably at least one, and preferably the majority, of the receiving chambers is transparent.

[0098] Another subject of the application is a method for textile cleaning in which a previously described detergent portion unit is introduced into the washing liquor of a textile washing machine.

[0099] 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.

[0100] The machine washing process preferably takes place at temperatures of 20°C to 60°C, preferably from 30°C to 45°C. Preferred textile washing processes are used for cleaning cotton fabrics. Examples
