Description

[0001] The present invention relates to a highly concentrated detergent preparation based on a combination of specific polyalkoxylated amines and alcohol polyalkoxylates. 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 3 122 849 B1 describes cleaning compositions which, in addition to other components, also contain polyalkoxylated amines.

[0006] International application WO 2017 / 151257 A1 describes alkoxylated diols and detergent compositions based on these alkoxylated diols.

[0007] Washing and cleaning agents are also known from WO 92 / 06153, JP 2007 / 161805, WO 97 / 26319, DE 102019216681, EP 3974507, WO 2022 / 063466 and US 4597898.

[0008] 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 storage properties, and are characterized in particular by good cleaning results. Specifically, the detergent preparation should be packaged in water-soluble portion packs.

[0009] The first subject matter of the application is a detergent preparation containing, based on its total weight, a) 0.5 to 4 wt% of a polyalkoxylated amine with a weight-average molecular weight Mw in the range of 600 g / mol to 10000 g / mol, obtainable by reacting ammonia or primary alkyl or hydroxyalkylamines having a molecular weight below 200 g / mol with alkylene oxides; b) 0.5 to 4 wt% of an alcohol polyalkoxylate with a weight-average molecular weight Mw in the range of 600 g / mol to 10000 g / mol, 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, wherein the alcohol polyalkoxylate is selected from the group of polypropylene glycols; and c) 0.1 to 3 wt.% of an ethylene oxide-propylene oxide-ethylene oxide triblock copolymer, wherein the copolymer comprises a first EO block, a second EO block and a PO block, wherein the first EO block and the second EO block are connected to the PO block.

(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.

[0049] Due to their improved cleaning effect, detergent preparations are preferred which contain, as a further optional component, 0.2 to 7 wt.%, preferably 0.5 to 5 wt.% enzyme preparation.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] According to the invention, it is preferred if the detergent preparation contains at least one lipase preparation. Preferred lipases 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).

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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®<.

[0058] 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.%.

[0059] 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.

[0060] 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.

[0061] 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,

[0062] The weight fraction of the protease preparation in the total weight of the detergent preparation is preferably 0.2 to 5 wt.%, preferably 0.4 to 4 wt.%.

[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.

[0064] 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.

[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 3.2.1.1.1), and within these, the glycosidases (EC 3.2.1.1.1), 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 detergent preparation preferably contains 0.01 to 1 wt.%, preferably 0.02 to 0.3 wt.% of a mannanase preparation.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.%.

[0073] As an additional preferred component, the detergent preparation contains a polyalkoxylated polyalkylenemine, which is obtainable by reacting polyalkylenemines with alkylene oxides. Particularly preferred detergent preparations, based on their cleaning performance, contain 0.5 to 10 wt%, preferably 0.5 to 6 wt%, of polyalkoxylated polyalkylenemine, based on their total weight.

[0074] 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.

[0075] A preferred detergent preparation optionally comprises 0.2 to 4 wt.%, preferably 0.5 to 3 wt.% fragrance preparation.

[0076] In addition to the actual fragrance ingredients, the fragrance preparation includes, for example, solvents, solid carrier materials or stabilizers.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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."

[0082] The composition of some preferably liquid (20°C, 1013 mbar) detergent preparations can be found in the following tables (values ​​in wt.% based on the total weight of the preparation unless otherwise specified). Formulas 1-4, 9-12, 17-20, 25-28, 33-36, 41-44 are not according to the invention. 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

[0083] 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.

[0084] 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.

[0085] Another preferred subject matter 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.

[0086] The water-soluble film in which the detergent preparation is packaged can comprise one or more structurally different water-soluble polymers.

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 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 22 ml, in particular from 12 to 20 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 matter 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. The textile cleaning method is preferably used for cleaning cotton fabrics or polyester.

[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 15 to 35°C, preferably from 15 to 25°C.
