Description

[0001] Color-stable liquid detergent

[0002] The present invention relates to color-stable liquid detergents. In particular, the invention relates to color-stable liquid detergents containing gluconic acid salt.

[0003] The packaging and distribution of detergents and laundry detergents are constantly evolving. For some time now, a key focus has been on convenient dosing of detergents and laundry detergents for consumers and simplifying the steps required for washing or cleaning. One solution is pre-portioned detergents or laundry detergents, for example, foil pouches with one or more compartments for solid or liquid detergents or laundry detergents. From a technical perspective, a key focus is on the development and production of liquid detergents suitable for packaging in water-soluble foil pouches.

[0004] The commercial success of a detergent portion unit is largely determined by the ability to provide a product that meets consumer interest.

[0005] An important means of communicating the product quality and product promise of a liquid detergent is its appearance, for example the color of a liquid detergent or the shape and color of a portion unit containing the liquid detergent. This applies in particular to water-soluble film pouches, whose soluble films are generally transparent and allow a view of the solid or liquid detergent contained within. Colored, i.e. non-white, liquid detergents can generally be produced easily by adding appropriate dyes to the liquid detergent. The temporal stability of the achieved color impression is influenced by the ingredients of the liquid detergent and the addition of stabilizing agents, among other factors. For example, international application WO 93 / 09215 A1 describes the stabilization of dyes in liquid detergents by adding sulfur-containing compounds such as sulfites.

[0006] Another key consideration in the successful marketing of a liquid detergent is its ecological footprint. The ecological footprint of a liquid detergent is determined not only by the amount of energy and water used in its production, but also by the biodegradability of the ingredients and packaging materials used. Providing liquid detergents with high performance while continually reducing their ecological footprint is another objective in the development of detergents and cleaning agents. In summary, the application was based on the task of providing a visually appealing, dye-containing liquid detergent characterized by high color stability.The liquid detergent should be characterized by a high concentration of active ingredients, be suitable for packaging in water-soluble foil bags, and contain a high proportion of easily biodegradable ingredients.

[0007] A first subject matter of the application is a liquid detergent containing, based on its total weight, a) 22 to 50 wt.% anionic surfactant; b) 0.1 to 8 wt.% gluconic acid salt; c) 0.01 to 2 wt.% antioxidant; d) 5 to 25 wt.% organic solvent; e) 0.1 to 15 wt.% water; f) less than 0.1 wt.% organic phosphonate;

[0008] The liquid detergents are characterized by surprising color stability when stored even under demanding conditions. This applies to both dye-free and dye-containing detergents, which retain their original coloration, which occurs during production, even under demanding storage conditions.

[0009] The detergent is liquid under standard conditions (20°C, 1013 mbar). Preferred detergents have a viscosity (21°C, Brookfield Viscometer Type DV-II. Pro, spindle no. 2, 20 rpm) above 400 mPas, preferably above 1000 mPas.

[0010] A first essential component of the liquid detergent is 12 to 45 wt.% anionic surfactant, with preferred liquid detergents containing, based on their total weight, 27 to 45 wt.%, preferably 32 to 40 wt.% anionic surfactant.

[0011] The anionic surfactant is preferably selected from the group comprising C9-C13 alkylbenzenesulfonates, olefinsulfonates, C12-C18 alkanesulfonates, estersulfonates, alk(en)yl sulfates, fatty alcohol ether sulfates, C12-C18 fatty acid salts, and mixtures thereof. Compositions comprising C8-C18 alkylbenzenesulfonates and fatty alcohol ether sulfates as anionic surfactant exhibit particularly good dispersing properties. Suitable sulfonate-type surfactants are preferably C8-C18 alkylbenzenesulfonates, olefinsulfonates, i.e., mixtures of alkene and hydroxyalkanesulfonates, and disulfonates, such as those obtained, for example, from C12-C18 monoolefins with a terminal or internal double bond by sulfonation with gaseous sulfur trioxide and subsequent alkaline or acidic hydrolysis of the sulfonation products.Also suitable are C12-C18 alkanesulfonates and the esters of α-sulfofatty acids (estersulfonates), for example, the α-sulfonated methyl esters of hydrogenated coconut, palm kernel, or tallow fatty acids. It is particularly preferred if the composition contains at least one anionic surfactant of formula (I). in the

[0012] R' and R" are independently H or alkyl and together contain 8 to 18, preferably 9 to 15 and especially 9 to 13 C atoms and Y + a monovalent cation or the nth part of an n-valent cation (in particular monoethanolamine).

[0013] The group of alkyl ether sulfates includes fatty alcohol ether sulfates, for example the sulfuric acid monoesters of straight-chain or branched C7-C2i alcohols ethoxylated with 1 to 6 mol of ethylene oxide, such as 2-methyl-branched C9-11 alcohols with an average of 3.5 mol of ethylene oxide (EO) or C12-18 fatty alcohols with 1 to 4 EO. Alkyl ether sulfates with the formula (II) are preferred.

[0014] R 1 -O-(AO) n -SO3- X + (II)

[0015] In this formula (II) R 1 represents a linear or branched, substituted or unsubstituted alkyl radical, preferably a linear, unsubstituted alkyl radical, particularly preferably a fatty alcohol radical. Preferred radicals R 1of formula (II) are selected from decyl, undecyl, dodecyl, tridecyl, tetradecyl, pentadecyl, hexadecyl, heptadecyl, octadecyl, nonadecyl, eicosyl radicals and mixtures thereof, with the representatives having an even number of carbon atoms being preferred. Particularly preferred radicals R 1 of formula (II) are derived from fatty alcohols with 12 to 18 C atoms, for example from coconut fatty alcohol, tallow fatty alcohol, lauryl, myristyl, cetyl or stearyl alcohol or from oxo alcohols with 10 to 20 C atoms.

[0016] In formula (II), AO represents an ethylene oxide (EO) or propylene oxide (PO) group, preferably an ethylene oxide group. The index n in formula (I) is an integer from 1 to 50, preferably from 1 to 20, and in particular from 2 to 10. n is most preferably 2, 3, 4, 5, 6, 7, or 8. X is a monovalent cation or the nth part of an n-valent cation, preferred being the alkali metal ions, and among these, Na + or K+ , where Na + is highly preferred. Further cations X+ can be selected from NHT, 1 Zn 2+ ,14 mg 2+ ,14 Ca 2+ ,14 Mn 2+ , and mixtures thereof as well as primary and secondary amines, in particular monoethanolamine.

[0017] Particularly preferred compositions contain an alkyl ether sulfate selected from fatty alcohol ether sulfates of the formula (III) with k = 11 to 19, n = 2, 3, 4, 5, 6, 7, or 8. Very particularly preferred representatives are Na fatty alcohol ether sulfates with 12 to 18 C atoms and 2 EO (k = 11 to 13, n = 2 in formula III). The stated degree of ethoxylation represents a statistical mean, which can be a whole or fractional number for a specific product. The stated degrees of alkoxylation represent statistical mean, which can be a whole or fractional number for a specific product. Preferred alkoxylates / ethoxylates have a narrow homolog distribution (narrow range ethoxylates, NRE).

[0018] In summary, preferred liquid detergents contain anionic surfactant selected from the group of Cs-18-alkylbenzenesulfonates, Cs-18-olefinsulfonates, Cs-12-18-alkanesulfonates, Cs-18-estersulfonates, Cs-18-alkyl sulfates, Cs-18-alkenyl sulfates, fatty alcohol ether sulfates and C12-18 fatty acid salts, preferably from the group of Cs-18-alkylbenzenesulfonates, Cs-18-alkyl sulfates, fatty alcohol ether sulfates and C12-18 fatty acid salts and in particular from the group of Cs-18-alkylbenzenesulfonates and C12-18 fatty acid salts.

[0019] The use of anionic surfactants from the group of alkanolamine-Cs-is-alkylbenzenesulfonates has proven to be particularly advantageous for the storage stability of liquid detergents.

[0020] In preferred liquid detergents, the anionic surfactant is selected from the group of alkanolamine Cs-18-alkylbenzenesulfonates with alkanolamine from the group monoethanolamine, monoisopropanolamine, diisopropanolamine, preferably from the group monoethanolamine.

[0021] Other preferred anionic surfactants come from the group of C12-18 fatty acid salts. Particularly preferred C12-18 fatty acid salts are selected from the group of caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, oleic acid, linoleic acid, and mixtures thereof.

[0022] In preferred liquid detergents, the anionic surfactant is selected from the group of alkanolamine Ci2-18 fatty acid salts with alkanolamine from the group monoethanolamine, monoisopropanolamine, diisopropanolamine, preferably from the group monoethanolamine.

[0023] The C12-18 fatty acid salts are classified in the application as anionic surfactants.

[0024] Both storage stability and washing and cleaning performance can be further improved by the composition of the surfactant system. In preferred detergents, the weight ratio of Cs-18-alkylbenzenesulfonate to C12-18 fatty acid salts is 8:1 to 2:1, preferably 7:1 to 5:2, and especially 6:1 to 3:1. Particularly preferred detergents are those in which the weight ratio of alkanolamine Cs-18-alkylbenzenesulfonate to alkanolamine C12-18 fatty acid salt is 8:1 to 2:1, preferably 7:1 to 5:2, and especially 6:1 to 3:1.

[0025] The detergents contain a nonionic surfactant as a preferred optional ingredient. Its proportion by weight of the total weight of the detergent is preferably 12 to 36 wt.%, particularly preferably 15 to 33 wt.%, and especially 18 to 30 wt.%.

[0026] The use of non-ionic surfactants from the group of alkyl ethoxylates is particularly preferred, with preferred alkyl ethoxylates being selected from the group of ethoxylated primary Cs-18 alcohols, preferably ethoxylated primary Cs-18 alcohols with a degree of alkoxylation of 4 to 10, particularly preferably Cs-12-14 alcohols with 4 EO or 7 EO, Cs-16-n alcohols with 7 EO, Cs-13-15 alcohols with 5 EO, 7 EO or 8 EO, Cs-18-oxo alcohols with 7 EO, Cs-12-18 alcohols with 5 EO or 7 EO, in particular Cs-12-18 fatty alcohols with 7 EO or Cs-18-oxo alcohols with 7 EO.

[0027] In summary, preferred detergents contain, based on their total weight, 12 to 36 wt.%, particularly preferably 15 to 33 wt.% and in particular 18 to 30 wt.% of nonionic surfactant from the group of ethoxylated primary Cs-is alcohols, preferably the ethoxylated primary Cs-is alcohols with a degree of alkoxylation of 4 to 10, particularly preferably the Cs-12-14 alcohols with 4 EO or 7 EO, the Cs-n alcohols with 7 EO, the Cs-is alcohols with 5 EO, 7 EO or 8 EO, the Cs-oxo alcohols with 7 EO, the Cs-alcohols with 5 EO or 7 EO, in particular the Cs-12-is fatty alcohols with 7 EO or the Cs-is oxo alcohols with 7 EO.

[0028] With regard to the rheological properties of the detergents, their processability and cleaning effect, it has proven advantageous to use non-ionic surfactant and anionic surfactant in a weight ratio of 3:1 to 1:3, preferably 2:1 to 1:2 and in particular 3:2 to 2:3.

[0029] As a further optional ingredient, preferred detergents contain 1 to 10% by weight, preferably 1.2 to 7% by weight and in particular 1.5 to 4% by weight of polyalkoxylated amine having a weight-average molecular weight Mw in the range from 600 g / mol to 10,000 g / mol, which is obtainable by reacting ammonia or primary alkyl or hydroxyalkylamines which have a molecular weight below 200 g / mol with alkylene oxides, in order to increase the washing or cleaning performance.

[0030] Preferred polyalkoxylated amines have a weight-average molecular weight Mw in the range from 1300 g / mol to 6000 g / mol, in particular from 1400 g / mol to 4500 g / mol. (The average molecular weights given here and later for other polymers are weight-average molecular weights Mw, which can generally be determined by gel permeation chromatography using an RI detector, with the measurement conveniently being 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 trialkanolamine, 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 reacted with an alkylene oxide, in particular selected from the group consisting of ethylene oxide, Propylene oxide, butylene oxide and mixtures thereof, in particular with a mixture containing propylene oxide and preferably ethylene oxide, particularly preferably with propylene oxide.The polyalkoxylated amines obtainable in this way can be block or random structures. Particular preference is given, inter alia, to a polyalkoxylated amine obtainable by propoxylation of triethanolamine, preferably with a length of each of the three side arms of 15 propylene oxide units. Likewise preferred is a polyalkoxylated amine obtainable by propoxylation of triisopropanolamine, preferably with a length of each of the three side arms of 15 propylene oxide units. Also suitable are polyalkoxylated monoalkylamines having a linear, branched, or cyclic alkyl group, wherein the alkoxylation is carried out 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, particularly preferably with propylene oxide.Also preferred is a polyalkoxylated amine obtainable by propoxylation of tert-butylamine, preferably with a length of the two side arms of 12 propylene oxide units each.

[0031] Preferred polyalkoxylated amines satisfy the general formula (IV), in which R represents a linear, optionally branched or optionally cyclic alkyl group with

[0032] 1 to 12 C atoms or a group -(CH2CHR'O) n -(CH2CHR“O) m -H stands,

[0033] R' and R" independently of one another represent H, CH3 or CH2CH3, n, n' and n" independently of one another represent numbers from 0 to 30, preferably from 0 to 10 and in particular from 0 to 5, and m, m' and m" independently of one another represent numbers from 0 to 30, preferably from 5 to 20 and in particular from 12 to 16, with the proviso that the sum n + n' + n" + m + m' + m" is at least 14, preferably in the range from 18 to 100 and in particular in the range from 20 to 70. Preferably, in the compounds of the formula I, at least one of the radicals R' and R" is a CHs group.

[0034] Polyalkoxylated amines that are particularly preferred due to their cleaning performance are those obtainable by reacting triethanolamine with alkylene oxides, preferably by reacting triethanolamine with ethylene oxide and propylene oxide. Polyalkoxylated amines that are obtainable by reacting triethanolamine with ethylene oxide and subsequent reaction with propylene oxide are very particularly preferred.

[0035] A second essential component of detergents is the gluconic acid salt. The weight fraction of the gluconic acid salt in the total weight of the detergent is preferably 0.2 to 6 wt.% and in particular 0.4 to 4 wt.%. The addition of the gluconic acid salt has proven particularly advantageous for stabilizing the dye in the liquid detergent. Due to its availability and ease of processing, the use of sodium gluconate is particularly preferred.

[0036] Another key ingredient in dye stabilization is the use of antioxidants. An antioxidant is a molecule that can slow or prevent the oxidation of other molecules. Oxidation reactions can produce free radicals, which in turn can trigger degradation chain reactions. Antioxidants stop these chain reactions by removing the free radical intermediates, inhibiting other oxidations, and preventing themselves from being oxidized. Therefore, antioxidants are often reducing agents.The antioxidant is preferably selected from the group consisting of butylhydroxyltoluene (BHT), butylhydroxylanisole (BHA), trimethoxybenzoic acid (TMBA), α-, β-, α- and δ-tocopherol (vitamin E acetate), 6-hydroxy-2,5,7,8-tetramethylchroman-2-carboxylic acid (Trolox), 1,2, benzisothiazolin-3-one (Proxel GLX), tannic acid, galic acid, Tinoguard AO-6, Tinoguard TS, ascorbic acid, alkylated phenol, ethoxyquin 2,2,4-trimethyl,1-2-dihydroquinoline, lignosulfonic acid and its salts, benzofuran, benzopyran, tocopherol sorbate, butylhydroxylbenzoic acid and its salts, galic acid and its alkyl esters, uric acid, its salts and alkyl esters, sorbic acid and their salts, dihydroxyfumaric acid and their salts and mixtures thereof.

[0037] Particularly preferred antioxidants are selected from the group of sulfites, hydrogen sulfites and disulfites, preferably from the group containing sodium sulfite, sodium hydrogen sulfite and sodium disulfite, in particular from the group containing sodium sulfite and sodium disulfite.

[0038] The use of antioxidants from the disulfite group, preferably from the sodium disulfite group, has proven particularly effective. The weight proportion of the antioxidant in the total weight of the detergent is preferably 0.02 to 1 wt.%, and in particular 0.05 to 0.5 wt.%.

[0039] As a further essential component, the detergent contains 5 to 25% by weight of organic solvent. The proportion of organic solvent in the total weight of the detergent is preferably 7 to 20% by weight and in particular 10 to 18% by weight.

[0040] Preferred organic solvents are selected from the group consisting of ethanol, n-propanol, i-propanol, butanols, glycol, propanediol, butanediol, methylpropanediol, glycerol, diglycol, propyldiglycol, butyldiglycol, hexylene glycol, ethylene glycol methyl ether, ethylene glycol ethyl ether, ethylene glycol propyl ether, ethylene glycol mono-n-butyl ether, diethylene glycol methyl ether, diethylene glycol ethyl ether, propylene glycol methyl ether,

[0041] Propylene glycol ethyl ether, propylene glycol propyl ether, dipropylene glycol monomethyl ether, dipropylene glycol monoethyl ether, methoxytriglycol, ethoxytriglycol, butoxytriglycol, 1-butoxyethoxy-2-propanol, 3-methyl-3-methoxybutanol, propylene glycol t-butyl ether, di-n-octyl ether, and mixtures thereof, preferably from the group consisting of propanediol, glycerin, and mixtures thereof. Any alkanolamine used to neutralize the anionic surfactant is not considered organic solvents.

[0042] The detergent contains water. Preferred detergents are those containing 5 to 15, preferably 8 to 15, wt.% water based on their total weight.

[0043] The weight fraction of organic phosphonate in the total weight of the detergent is less than 0.1 wt.%. Preferred detergents contain no organic phosphonate, in particular no phosphonate at all. Examples of phosphonate compounds that are preferably not present in the detergent are phosphonates from the group of hydroxyalkane and / or aminoalkanephosphonates, in particular from the group of 1-hydroxyethane-1,1-diphosphonate (HEDP), ethylenediaminetetramethylenephosphonate (EDTMP), and diethylenetriaminepentamethylenephosphonate (DTPMP).

[0044] As mentioned at the beginning, the detergents are characterized by surprisingly high color stability, even under demanding storage conditions. This applies to both dye-free and dye-containing detergents.

[0045] Preferred detergents contain dye as an optional ingredient. The dye is preferably selected from the group of water-soluble dyes, in particular from the group of water-soluble acid dyes, water-soluble direct dyes, and water-soluble polymer dyes, in particular water-soluble polymer dyes.

[0050] The weight fraction of the dye in the total weight of dye-containing detergents is preferably 0.001 to 0.5 wt.%, more preferably 0.002 to 0.3 wt.%, and in particular 0.005 to 0.2 wt.%.

[0053] Preferred detergents contain washing or cleaning-active polymers. Particularly preferred washing or cleaning-active polymers are selected from the group of soil release polymers, dye transfer inhibitors, graying inhibitors, and anti-redeposition agents.

[0054] Soil release agents are components that positively influence the ability of textiles to be washed out of oil and grease. This effect is particularly noticeable when a textile is soiled that has already been washed several times with an agent containing this oil and grease-dissolving component. Preferred soil release agents include, for example, non-ionic cellulose ethers such as methylcellulose and methylhydroxypropylcellulose with a methoxyl group content of 15 to 30 wt.% and a hydroxypropoxyl group content of 1 to 15 wt.%, based in each case on the non-ionic cellulose ether, as well as the polymers of phthalic acid and / or terephthalic acid or their derivatives with monomeric and / or polymeric diols known from the prior art, in particular polymers of ethylene terephthalates and / or polyethylene glycol terephthalates or anionically and / or non-ionically modified derivatives thereof.Also preferred are anionic or nonionic polyesters of polypropylene terephthalates. These are commercially available, for example, under the trade name Texcare®. In summary, preferred detergents are those containing washing- or cleaning-active polymers from the group of phthalic acid and / or terephthalic acid or derivatives thereof with monomeric and / or polymeric diols, preferably from the group of polymers of ethylene terephthalates and / or polyethylene glycol terephthalates and / or polypropylene terephthalates or anionically and / or nonionically modified derivatives thereof, particularly preferably from the group of anionic or nonionic polyesters of polypropylene terephthalates.

[0055] It is preferred that the dye transfer inhibitor is a polymer or copolymer of cyclic amines, such as vinylpyrrolidone and / or vinylimidazole. Polymers suitable as dye transfer inhibitors include polyvinylpyrrolidone (PVP), polyvinylimidazole (PVI), copolymers of vinylpyrrolidone and vinylimidazole (PVP / PVI), polyvinylpyridine N-oxide, poly-N-carboxymethyl-4-vinylpyridium chloride, polyethylene glycol-modified copolymers of vinylpyrrolidone and vinylimidazole, and mixtures thereof. Particularly preferred dye transfer inhibitors are polyvinylpyrrolidone (PVP), polyvinylimidazole (PVI), or copolymers of vinylpyrrolidone and vinylimidazole (PVP / PVI). The polyvinylpyrrolidones (PVP) used preferably have an average molecular weight of 2,500 to 400,000 and are commercially available from ISP Chemicals as PVP K 15, PVP K 30, PVP K 60 or PVP K 90 or from BASF as Sokalan® HP 50 or Sokalan® HP 53.The copolymers of vinylpyrrolidone and vinylimidazole (PVP / PVI) used preferably have a molecular weight in the range of 5,000 to 100,000 g / mol. A commercially available PVP / PVI copolymer is, for example, from BASF under the name Sokalan® HP 56.

[0056] The purpose of graying inhibitors is to keep the dirt detached from the textile fibers suspended in the liquor. Suitable for this purpose are water-soluble colloids, usually of an organic nature, such as starch, glue, gelatin, salts of ether carboxylic acids or ether sulfonic acids of starch or cellulose, or salts of acidic sulfuric acid esters of cellulose or starch. Water-soluble polyamides containing acidic groups are also suitable for this purpose. Starch derivatives other than those mentioned above can also be used, for example, aldehyde starches. Cellulose ethers, such as carboxymethylcellulose (sodium salt), methylcellulose, hydroxyalkylcellulose, and mixed ethers, such as methylhydroxyethylcellulose, methylhydroxypropylcellulose, methylcarboxymethylcellulose, and mixtures thereof, are preferred.

[0057] As antiredeposition agents, (co)polymers based on polyethyleneimine, polyvinyl acetate and polyethylene glycol can be used in particular, preferably in mixtures with antiredeposition agents.

[0058] Very particular preference is given to using ethoxylated polyethyleneimine with ethylene oxide segments which are bonded to the nitrogen atoms of the polyethyleneimine, the weight proportion of this ethoxylated polyethyleneimine in the total weight of the detergent preferably being 1 to 10 wt.%, preferably 1.2 to 7 wt.%, and in particular 1.5 to 4 wt.%.

[0059] The ethoxylated polyalkyleneimine is a polymer with a polyalkyleneimine backbone bearing polyalkoxy groups on the nitrogen atoms. The ethoxylated polyethyleneimine preferably has a polyethyleneimine backbone with a weight-average molecular weight in the range from 100 g / mol to 2000 g / mol, in particular from 400 g / mol to 800 g / mol. The weight-average molecular weight of the ethoxylated polyethyleneimine is preferably from 5000 g / mol to 20,000 g / mol, in particular from 8000 g / mol to 14,000 g / mol.

[0060] The polyalkyleneimine has primary amino functions at the ends and preferably both secondary and tertiary amino functions in the interior; optionally, it can also have only secondary amino functions in the interior, resulting in a linear rather than a branched-chain polyalkyleneimine. The ratio of primary to secondary amino groups in the polyalkyleneimine is preferably in the range from 1:0.5 to 1:1.5, in particular in the range from 1:0.7 to 1:1. The ratio of primary to tertiary amino groups in the polyalkyleneimine is preferably in the range from 1:0.2 to 1:1, in particular in the range from 1:0.5 to 1:0.8. The nitrogen atoms in the polyalkyleneimine are separated from one another by alkylene groups having 2 to 12 carbon atoms, in particular 2 to 6 carbon atoms, although 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 functions in the polyalkyleneimine can carry one or two polyalkoxy groups, and the secondary amino functions can carry one polyalkoxy group, although not every amino function needs to be substituted by an alkoxy group. The average number of alkoxy groups per primary and secondary amino function in the ethoxylated polyalkyleneimine is preferably 5 to 100, especially 10 to 50. The ethoxylated polyalkyleneimines are obtainable by reacting the polyalkyleneimines with ethylene oxide.

[0061] In summary, particularly preferred detergents contain washing or cleaning-active polymers from the group of carboxymethylcelluloses, non-ionic cellulose ethers, polyalkoxylated polyethyleneimines and (co)polymers of phthalic acid or terephthalic acid.

[0062] To further increase the cleaning performance, preferred detergents contain, based on their total weight, 0.5 to 7 wt.%, preferably 1.0 to 6 wt.% enzyme preparations.

[0063] In addition to the actual enzyme protein, an enzyme preparation comprises 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 used 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 can be present in an amount of 0.05 to 35 wt.%, preferably 0.05 to 10 wt.%, based on the total weight of the enzyme composition.

[0064] The protein concentration can be determined using known methods, such as the BCA method (bicinchoninic acid; 2,2'-biquinolyl-4,4'-dicarboxylic acid) or the biuret method. The active protein concentration is determined by titrating the active sites using a suitable irreversible inhibitor (for proteases, for example, phenylmethylsulfonyl fluoride (PMSF)) and determining the residual activity.

[0065] The detergents preferably contain at least one enzyme preparation, particularly preferably at least three enzyme preparations of enzymes from the group consisting of lipase, mannanase, amylase, protease, cellulase, hexosaminidase, preparations of a pectinolytic enzyme and endoglucanase.

[0066] Detergents preferred with regard to their cleaning performance contain, based on their total weight, 0.1 to 0.4 wt.% and in particular 0.2 to 0.3 wt.% of hexosaminidase preparation, particularly preferably ß-hexosaminidase preparation.

[0067] The term “hexosaminidase” refers to a polypeptide with hexosaminidase activity (hexosaminidases) and includes enzymes that catalyze the hydrolysis of N-acetyl-D-hexosamine or N-acetyl-glucosamine polymers.

[0068] Polypeptides with hexosaminidase activity include dispersins such as Dispersin B (DspB), which are ß-N-acetylglucosamine dispersins belonging to the glycoside hydrolase 20 family. Dispersins are produced by the periodontal pathogen Aggregatibacter actinomycetemcomitans, a Gram-negative oral bacterium. Dispersin B is a ß-hexosaminidase that specifically hydrolyzes ß-1,6-glycosidic bonds of acetylglucosamine polymers. The use of hexosaminidases from the ß-hexosaminidase group is preferred.

[0069] According to the invention, it is preferred if the detergent contains at least one lipase preparation. Lipases preferred according to the invention are selected from at least one enzyme from 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).

[0070] 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®, for example, is naturally present in Rhizopus oryzae. Lipase M-AP10®, for example, is naturally present in Mucor javanicus. A highly preferred lipase is commercially available under the trade name Lipex® from Novozymes (Denmark) and can be advantageously used in the detergents according to the invention. Lipase Lipex® 100 L is particularly preferred.

[0071] Preferred detergents are characterized in that they contain, based on their total weight, 0.01 to 1 wt.%, in particular 0.05 to 0.3 wt.%, of lipase preparation.

[0072] The detergents 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 the α-amylases from Bacillus licheniformis, from B. amyloliquefaciens, and from B. stearothermophilus, as well as their improved further developments 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 developments 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, available as Keistase®. The α-amylase from 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 are the further developments of the α-amylase from Aspergillus niger and A. oryzae, available from Novozymes under the trade name Fungamyl®.

[0073] The weight proportion of the amylase preparation, in particular the a-amylase preparation, in the total weight of the detergent is preferably 0.1 to 2 wt.%, in particular 0.2 to 1 wt.%.

[0074] According to the invention, it is preferred if the detergent contains at least one protease as an enzyme. A protease is an enzyme that cleaves peptide bonds by hydrolysis. According to the invention, any of the enzymes from class EC 3.4 falls under this (comprising each of the thirteen subclasses falling under it). According to the invention, "protease activity" is present if the enzyme possesses proteolytic activity (EC 3.4). Various types of protease activity are known: The three main types are: trypsin-like, in which cleavage of the amide substrate occurs after the amino acids Arg or Lys at P1; chymotrypsin-like, in which cleavage occurs after one of the hydrophobic amino acids at P1; and elastase-like, in which cleavage of the amide substrate occurs after Ala at P1.

[0075] Surprisingly, it was found that a protease of the alkaline protease type from Bacillus lentus DSM 5483, or a sufficiently similar protease (in terms of sequence identity) that exhibits several of these modifications in combination, is particularly suitable for use in the detergents according to the invention and is advantageously stabilized therein. Advantages of using this protease thus arise, in particular, with regard to washing performance and / or stability.

[0076] Most preferably, the detergent according to the invention contains protease of the alkaline protease type from Bacillus lentus DSM 5483 or a sufficiently similar protease (based on sequence identity) which has several of these changes in combination,

[0077] The weight proportion of the protease preparation in the total weight of the detergent is preferably 0.2 to 4 wt% and in particular 0.4 to 3 wt%.

[0078] Preferred detergents further contain, as an optional ingredient, 0.05 to 2% by weight, preferably 0.1 to 0.4% by weight, of a preparation of a pectinolytic enzyme, based on their total weight.

[0079] The pectinolytic enzymes in the context of the present invention include enzymes with the names pectinase, pectate lyase, pectin esterase, pectin demethoxylase, pectin methoxylase, pectin methylesterase, pectase, pectin methylesterase, pectin esterase, pectin pectylhydrolase, pectin depolymerase, 20 endopolygalacturonase, pectolase, pectin hydrolase, pectin polygalacturonase, endo-polygalacturonase, poly-α-1,4-galacturonide glycanhydrolase, endogalacturonase, endo-D-galacturonase, galacturan 1,4-α-galacturonidase, exopolygalacturonase, poly(galacturonate) hydrolase, exo-D-galacturonase, exo-D- Galacturonanase, Exopoly-DGalacturonase, Exo-poly-a-Galacturonosidase,

[0080] Exopolygalacturonosidase or 25 exopolygalacturanosidase. The use of pectate lyases is particularly preferred.

[0081] Within the EC classification of enzymes, the numerical classification system for enzymes, the pectinolytic enzymes belong in particular to the enzyme classes (Enzyme Commission number) EC 3.1.1.11, EC 3.2.1.15, EC 3.2.1.67 and EC 3.2.1.82 and thus belong to the third of the six main enzyme classes, the 10 hydrolases (EC3), of which the glycosylases (EC 3.2.-.-) and, in turn, 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 that contain pectic acid and / or other galacturonans and catalyze their hydrolysis.

[0082] Pectate lyases within the meaning of the invention are enzymes that catalyze the non-hydrolytic cleavage of pectate by an endo-mechanism. Examples of suitable pectinolytic enzymes are the enzymes and enzyme preparations available under the trade names Gamanase®, Pektinex 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 B1 L® from AB Enzymes, and under the trade name Pyrolase® from Diversa Corp., San Diego, CA, USA.

[0083] As a preferred ingredient, the detergent contains 0.01 to 1 wt.%, preferably 0.02 to 0.3 wt.% of a mannanase preparation.

[0084] A mannanase catalyzes the hydrolysis of 1,4-beta-D-mannosidic bonds in mannans, galactomannans, glucomannans, and galactoglucomannans. These mannanases are classified as EC 3.2.1.78 according to enzyme nomenclature.

[0085] As a further preferred ingredient, the detergents 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-endoglucanhydrolase, celludextrinase, or avicelase. The decisive factor for whether an enzyme is a cellulase within the meaning of the invention is its ability to hydrolyze 1,4-ß-D-glucosidic bonds in cellulose.

[0086] Cellulases (endoglucanases, EG) suitable according to the invention include, for example, fungal, endoglucanase (EG)-rich compositions which are offered by the company Novozymes under the trade name Celluzyme®. The products Endolase® and Carezyme®, also available from Novozymes, are based on the 50 kD EG and the 43 kD EG from Humicola insolens DSM 1800, respectively. Other commercial products from this company that can be used are Cellusoft®, Renozyme® and Celluclean®. Also suitable are cellulases available from AB Enzymes, Finland, under the trade names Ecostone® and Biotouch®, which are based at least in part on the 20 kD EG from Melanocarpus. Other cellulases from AB Enzymes are Econase® and Ecopulp®. Other suitable cellulases are those from Bacillus sp. CBS 670.93 and CBS 669.93, with the one from Bacillus sp. CBS 670.93 is available from Danisco / Genencor under the trade name Puradax®. Other commercial products available from Danisco / Genencor are "Genencor detergent cellulase L" and lndiAge®Neutra.

[0087] The weight fraction of the cellulase preparation in the total weight of the detergent is preferably 0.01 to 1 wt.%, preferably 0.05 to 0.3 wt.%. The composition of some preferred detergents can be found in the following tables (The data are in wt.% based on the total weight of the preparation unless otherwise stated. The symbol stands for "free from".) The detergents are packaged in the form of detergent portion units in which the detergent preparation is completely enclosed in a water-soluble film.

[0088] The detergent according to the invention is characterized by high color stability and is therefore particularly suitable for packaging in transparent packaging. Preferred detergents are packaged in transparent containers. The transparent container allows the detergent to be perceived within the container. Examples of such transparent packaging include transparent plastic bottles or transparent, water-soluble foil bags.

[0089] "Transparent" or "transparency" means that the transmittance within the visible spectrum of light (410 to 800 nm) is greater than 20%, preferably greater than 30%, most preferably greater than 40%, and in particular greater than 50%. Thus, as soon as a wavelength of the visible spectrum of light has a transmittance greater than 20%, it is considered transparent within the meaning of the invention. A further preferred subject matter of this application is a detergent portion unit comprising i) a detergent; ii) a transparent, water-soluble film that completely encloses the detergent.

[0090] The water-soluble film enclosing the detergent can comprise one or more structurally different water-soluble polymers. Particularly suitable water-soluble polymers are polymers from the group of (optionally acetalized) polyvinyl alcohols (PVAL) and their copolymers.

[0151] Examples

[0152] Example 1

[0153] The following five liquid detergents were made by blending their ingredients.

[0154] Table 1 a: Detergents (wt%)

[0155] 1 > Texcare SRN 170

[0156] 2 > ethoxylated polyethyleneimine with ethylene oxide segments bonded to the nitrogen atoms of the polyethyleneimine

[0157] The dye-free liquid detergents were stored at 40°C for 4 weeks after production. The color of the liquid detergents was determined immediately after production, as well as after 2 and 4 weeks. To determine the Klett color number, 3 ml of the undiluted samples were filled into 10x10x45mm polystyrene cuvettes (2x optical) and measured using a colorimeter (Lico 3000 Dr. Lange spectral colorimeter). The color number increases with increasing color. Detergents with a Klett color number >1000 are not unusable.

[0158] Table 1 b: Klett color number (measured value)

[0159] * Simulation “Summer”: Storage with oscillating temperatures between 24 and 40°C Table 1c: Klett color number (change compared to t=0)

[0160] ** Difference cannot be determined

[0161] It can be seen from the measured values ​​that the detergents of the composition E1 according to the invention are distinguished from the comparative compositions V1 to V4 by a low color number and thus by a weaker coloration both at the time of their production and after storage at elevated temperature.

[0162] Furthermore, the detergents of the composition E1 according to the invention exhibit a smaller relative color change after storage compared to the original color.
