Description

[0001] CONCENTRATED DETERGENT PREPARATION WITH IMPROVED PROPERTIES

[0002] The present invention relates to a polymer-based, highly concentrated detergent preparation. Furthermore, the application 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.

[0003] The packaging and distribution of detergents and cleaning agents are constantly evolving. A key focus for some time now has been on convenient dosing of detergents and cleaning agents by the consumer and simplifying the steps required for a washing or cleaning process. Pre-portioned detergents or cleaning agents, for example, foil pouches with one or more compartments for solid or liquid detergents or cleaning agents, offer a technical solution.

[0004] A relevant trend for the production of these film bags is the miniaturization of these bags. This development is driven not only by increased consumer acceptance due to easier handling, but also by sustainability considerations, for example, with regard to transport volumes and costs and the amount of packaging used.

[0005] The concentration of modern detergents, especially modern liquid detergents, generally affects their optical and rheological properties, impacts their storage stability, and can affect their cleaning performance, especially if the high concentration of active ingredients leads to incompatibilities. Substance classes that have gained increasing importance in the course of the concentration of detergent formulations are enzymes and washing and cleaning-active polymers.

[0006] WO 2016 / 191238 describes textile detergents containing ethoxylated polyethyleneimine and alkyl ether sulfate.

[0007] WO 2022 / 063487 describes textile detergents based on a combination of polyalkoxylated amines and alkyleneimines.

[0008] The present application was based on the object of providing visually appealing, concentrated, flowable detergent preparations that can be produced and portioned simply and efficiently, exhibit good storage stability, and are characterized, in particular, by good cleaning results. In particular, the detergent preparation should be packaged in water-soluble sachets and be based predominantly on ingredients that can be produced at least partially from renewable raw materials.

[0009] A first subject matter of the application is a detergent preparation comprising, based on its total weight, a) 1 to 8 wt. % 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 having a molecular weight below 200 g / mol with alkylene oxides; b) 0.5 to 8 wt. % of ethoxylated polyethyleneimine having ethylene oxide segments bonded to the nitrogen atoms of the polyethyleneimine; c) 0.5 to 7 wt. % of alkoxylated polyethyleneimine having alkylene oxide segments bonded to the nitrogen atoms of the polyethyleneimine, wherein the alkylene oxide segments comprise ethylene oxide segments and Cs-Cs alkylene oxide segments.

[0010] The detergent preparation is preferably free-flowing under standard conditions (20°C, 1,013 mbar). Preferred detergent preparations have a viscosity (21°C, Brookfield viscometer type DV-II. Pro, spindle no. 2, 20 rpm) above 400 mPas, preferably above 1,000 mPas.

[0011] The core of the detergent formulation is the combination of three detergent-active polymers. Surprisingly, this combination has been shown to improve the detergent formulation's cleaning performance.

[0012] A first optional component of the detergent preparation is the polyalkoxylated amine a). The weight fraction of this amine in the total weight of the detergent preparation is 1 to 8 wt.%, preferably 2 to 7 wt.%, and in particular 3 to 6 wt.%.

[0013] Preferred polyalkoxylated amines have a weight-average molecular weight Mw in the range from 1,300 g / mol to 6,000 g / mol, in particular from 1,400 g / mol to 4,500 g / mol. (The average molecular weights stated 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 monoalkyldialkanolamine 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 thus obtainable 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. Also 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.

[0014] Preferred polyalkoxylated amines satisfy the general formula (I), in which R represents a linear, optionally branched or optionally cyclic alkyl group having 1 to 12 C atoms or a group -(CH2CHR'O) n -(CH2CHR“O) m -H stands,

[0015] 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.

[0016] 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.

[0017] As a further optional component, the detergent preparation contains, in addition to the polyalkylene imine a), an ethoxylated polyalkyleneimine b) with ethylene oxide segments bonded to the nitrogen atoms of the polyethyleneimine. Detergent preparations particularly preferred due to their cleaning performance contain, based on their total weight, 0.7 to 6 wt.%, preferably 1 to 4 wt.%, of ethoxylated polyethyleneimine b).

[0018] The ethoxylated polyalkyleneimine b) is a polymer with a polyalkyleneimine backbone bearing polyalkoxy groups on the nitrogen atoms. The ethoxylated polyethyleneimine b) preferably has a polyethyleneimine backbone with a weight-average molecular weight in the range from 100 g / mol to 2,000 g / mol, in particular from 400 g / mol to 800 g / mol. The weight-average molecular weight of the ethoxylated polyethyleneimine b) is preferably from 5,000 g / mol to 20,000 g / mol, in particular from 8,000 g / mol to 14,000 g / mol. The polyalkyleneimine has primary amino functions at the ends and preferably both secondary and tertiary amino functions in the interior. If necessary, it may also contain only secondary amino functions in the interior, resulting in a linear polyalkyleneimine rather than a branched chain one.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 N atoms in the polyalkyleneimine are separated from one another by alkylene groups having 2 to 12 C atoms, in particular 2 to 6 C atoms, although not all of the alkylene groups need to have the same number of C 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 1 or 2 polyalkoxy groups and the secondary amino functions can carry 1 polyalkoxy group, although not every amino function has to be substituted by alkoxy groups.The average number of alkoxy groups per primary and secondary amino function in the ethoxylated polyalkylenimine is preferably 5 to 100, in particular 10 to 50. The ethoxylated polyalkylenimines are accessible by reacting the polyalkylenimines with ethylene oxide.

[0019] The third essential component of the detergent preparation is the alkoxylated polyethyleneimines c). The alkoxylated polyethyleneimines c) are different from the ethoxylated polyethyleneimines b).

[0020] The weight fraction of the alkoxylated polyethyleneimine in the total weight of the detergent preparation is preferably 0.7 to 5 wt.% and in particular 1 to 3 wt.% alkoxylated polyethyleneimine c). These weight fractions have proven particularly advantageous with regard to the desired cleaning performance.

[0021] The ethoxylated polyalkyleneimine c) is a polymer with a polyalkyleneimine backbone bearing polyalkoxy groups on the nitrogen atoms. The alkoxylated polyethyleneimine c) 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 alkoxylated polyethyleneimine c) is preferably from 1,000 g / mol to 1,000,000 g / mol, particularly preferably from 5,000 to 500,000 g / mol, and in particular from 10,000 g / mol to 50,000 g / mol.

[0022] 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 alkoxylated polyalkyleneimine is preferably 5 to 100, especially 10 to 50.

[0023] The alkylene oxide segments of the alkoxylated polyethyleneimine c) preferably comprise ethylene oxide segments and C8-alkylene oxide segments. Very particular preference is given to alkoxylated polyethyleneimines c) in which the alkylene oxide segments consist of ethylene oxide segments and C3-alkylene oxide segments. These preferred alkoxylated polyalkyleneimines c) are obtainable, for example, by reacting the polyalkyleneimines with ethylene oxide and propylene oxide. Very particular preference is given to alkoxylated polyalkyleneimines c) which are obtainable by reacting polyalkyleneimines with ethylene oxide and subsequent reaction with propylene oxide.

[0024] For the cleaning performance of the detergent composition, it has proven advantageous if the ethoxylated polyethyleneimine b) and the alkoxylated polyethyleneimine c) are present in a weight ratio of 3:2 to 2:3, preferably 4:3 to 3:4.

[0025] For the same reason, detergent preparations are preferred in which the weight ratio of polyalkoxylated amine a) to the alkoxylated polyethyleneimines b) and c) is from 2:1 to 1:2, preferably from 3:2 to 2:3.

[0026] Preferred detergent preparations contain, based on their total weight, 35 to 60 wt.%, preferably 40 to 55 wt.% surfactant.

[0027] The group of surfactants includes nonionic, anionic, cationic, and amphoteric surfactants. The compositions according to the invention can comprise one or more of the aforementioned surfactants. Particularly preferred compositions contain surfactants from the group of anionic and nonionic surfactants.

[0028] 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, and mixtures thereof. Compositions comprising C8-C13 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. Preferred detergent preparations contain, based on their total weight, 18 to 40 wt.%, preferably 24 to 36 wt.% anionic surfactant.

[0029] It is particularly preferred if the composition contains at least one anionic surfactant of formula (II),

[0030] (II) in which R' and R" are independently H or alkyl and together contain 8 to 18, preferably 9 to 15 and in particular 9 to 13 C atoms and Y + a monovalent cation or the nth part of an n-valent cation (in particular monoethanolamine).

[0031] 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 Cg-n 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 (III) are preferred.

[0032] R 1 -O-(AO) n -SO3- X + (III)

[0033] 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 (III) 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 (III) 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.

[0034] AO in formula (III) is an integer from 1 to 50, preferably from 1 to 20 and in particular from 2 to 10. Most preferably, n is 2, 3, 4, 5, 6, 7 or 8. X is a monovalent cation or the n-th part of an n-valent cation, preferably the alkali metal ions and among them Na + or K + , where Na + is highly preferred. Further cations X+ can be selected from NHT, % Zn 2+ ,% Mg2+ ,% Ca 2+ ,% Mn 2+ , and mixtures thereof as well as primary and secondary amines, in particular monoethanolamine.

[0035] Particularly preferred compositions contain an alkyl ether sulfate selected from fatty alcohol ether sulfates of the formula (IV) where k = 1 from 1 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 = 1 from 1 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).

[0036] Although alkyl ether sulfates can generally be used in detergent preparations, the addition of an anionic surfactant from the group of Cs-C10 alkylbenzenesulfonates has proven superior in terms of cleaning performance. In a particularly preferred embodiment, the detergent preparation contains, based on its total weight, less than 10 wt.%, preferably less than 5 wt.%, particularly preferably less than 2 wt.%, and in particular no anionic surfactant from the group of alkyl ether sulfates.

[0037] In summary, preferred detergent preparations contain, based on their total weight, 15 to 35 wt.%, preferably 18 to 32 wt.% of anionic surfactant from the group of Cs-is-alkylbenzenesulfonates.

[0038] The use of anionic surfactants from the group of alkanolamine Cs-is-alkylbenzenesulfonates has proven to be particularly advantageous for the storage stability of the detergent preparation.

[0039] In preferred detergent preparations, the anionic surfactant is selected from the group of alkanolamine Cs-is-alkylbenzenesulfonates with alkanolamine from the group monoethanolamine, monoisopropanolamine, diisopropanolamine, preferably from the group monoethanolamine.

[0040] In very particularly preferred detergent preparations, the weight fraction of anionic surfactants from the group of alkanolamine Cs-is-alkylbenzenesulfonates, preferably from the group of alkanolamine Cs-is-alkylbenzenesulfonates with alkanolamine from the group monoethanolamine, monoisopropanolamine, diisopropanolamine, in particular from the group monoethanolamine, is 15 to 35 wt.%, preferably 18 to 32 wt.%.

[0041] The use of fatty acids has proven advantageous for storage stability. Preferred detergent preparations therefore contain, based on their total weight, 4 to 12% by weight, preferably 6 to 10% by weight, of fatty acid. Particularly preferred fatty acids are selected from the group of C12-18 fatty acids, preferably from the group 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 classified as anionic surfactants.

[0042] The detergent preparations contain a nonionic surfactant as a further preferred optional ingredient. Its weight proportion of the total weight of the detergent preparation is preferably 12 to 30 wt.%, preferably 15 to 28 wt.%, and in particular 18 to 26 wt.%. In particular, the use of non-ionic surfactants from the group of alkyl ethoxylates is 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 > 4, particularly preferably Cs-12-14 alcohols with 4 EO or 7 EO, Cs-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-alcohols with 5 EO or 7 EO, in particular Cs-12 fatty alcohols with 7 EO or Cs-18 oxo alcohols with 7 EO.

[0043] 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 nonionic surfactant from the group of ethoxylated primary Cs-is alcohols, preferably the ethoxylated primary Cs-is alcohols with a degree of alkoxylation > 4, 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-is alcohols with 5 EO or 7 EO, in particular the Cs-is fatty alcohols with 7 EO or the Cs-is oxo alcohols with 7 EO.

[0044] With regard to the rheological properties of the detergent preparation, its processability and cleaning effect, it has proven advantageous to use non-ionic surfactant and anionic surfactant in a weight ratio of 3:1 to 1:3, preferably 2:1 to 1:2 and in particular 3:2 to 2:3.

[0045] Preferred detergent preparations contain, based on their total weight, 5 to 20 wt.%, preferably 7 to 18 wt.% water.

[0046] In addition to water, at least one organic solvent is preferably used as an additional solvent. The use of aqueous-organic solvent systems has proven particularly advantageous for manufacturability and storage and is therefore preferred.

[0047] In a preferred embodiment, the detergent preparation contains, based on its total weight, 5 to 30 wt.%, preferably 10 to 20 wt.% of organic solvent.

[0048] Preferred organic solvents are selected from the group ethanol, n-propanol, i-propanol, butanols, glycol, propanediol, butanediol, methylpropanediol, glycerol, diglycol, propyl diglycol, butyl diglycol, hexylene glycol, ethylene glycol methyl ether, ethylene glycol ethyl ether, ethylene glycol propyl ether, ethylene glycol mono-n-butyl ether, diethylene glycol methyl ether, diethylene glycol ethyl ether, propylene glycol methyl ether, propylene glycol ethyl ether, propylene glycol propyl ether, dipropylene glycol monomethyl ether, dipropylene glycol monoethyl ether, methoxytriglycol, ethoxytriglycol, butoxytriglycol, 1-butoxyethoxy-2-propanol, 3-methyl-3-methoxybutanol, propylene glycol t-butyl ether, di-n-octyl ether and mixtures thereof, preferably from the group Propanediol, glycerin, monoethanolamine and their mixtures.

[0049] The detergent preparation contains a phosphonate as a preferred optional ingredient.

[0050] The weight fraction of the phosphonate in the total weight of the detergent preparation is preferably 0.1 to 3 wt.% and in particular 0.2 to 1 wt.%. The phosphonate compound is preferably a phosphonate from the group of hydroxyalkane and / or aminoalkanephosphonates, preferably from the group of aminoalkanephosphonates, and in particular from the group of ethylenediaminetetramethylenephosphonate (EDTMP) and diethylenetriaminepentamethylenephosphonate (DTPMP).

[0051] To further increase the cleaning performance, preferred detergent preparations contain, based on their total weight, 0.5 to 7 wt.%, preferably 1.0 to 6 wt.% enzyme preparations.

[0052] 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.

[0053] The protein concentration can be determined using known methods, for example, the BCA method (bicinchoninic acid; 2,2'-biquinolyl-4,4'-dicarboxylic acid) or the biuret method. 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.

[0054] It is preferred if the detergent preparation contains at least one enzyme preparation, preferably at least three enzyme preparations of enzymes from the group lipase, mannanase, amylase, protease, cellulase, hexosaminidase, preparations of a pectinolytic enzyme and endoglucanase.

[0055] Detergent preparations 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.

[0056] 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.

[0057] Polypeptides with hexosaminidase activity include dispersins such as Dispersin B (DspB), which are ß-N-acetylglucosamine glycerides 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 group of ß-hexosaminidases is preferred. 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 from the group formed by triacylglycerol lipase (EC 3.1.1.3), lipoprotein lipase (EC 3.1.1.34) and monoglyceride lipase (EC 3.1.1.23).

[0058] 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.

[0059] 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. Lipase Lipex® 100 L is particularly preferred.

[0060] Preferred detergent preparations 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.

[0061] 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 the α-amylases from Bacillus licheniformis, from B. amyloliquefaciens, and from β. stearothermophilus, as well as their improved versions for use in detergents or cleaning agents. The enzyme from β. 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, as Keistase®. The α-amylase of β.amyloliquefaciens is marketed by Novozymes under the name BAN®, and derivatives of the α-amylase from β. 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®.

[0062] The weight proportion of the amylase preparation, in particular the a-amylase preparation, in the total weight of the detergent preparation is preferably 0.1 to 2 wt.%, in particular 0.2 to 1 wt.%.

[0063] 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, 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.

[0064] 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 detergent preparations 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.

[0065] Most preferably, the detergent preparation 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.

[0066] The weight proportion of the protease preparation in the total weight of the detergent preparation is preferably 0.2 to 4 wt% and in particular 0.4 to 3 wt%.

[0067] Preferred detergent preparations further contain, as an optional ingredient, based on their total weight, 0.05 to 2 wt.%, preferably 0.1 to 0.4 wt.% of a preparation of a pectinolytic enzyme.

[0068] For the purposes of the present invention, the pectinolytic enzymes include enzymes with the names pectinase, pectate lyase, pectin esterase, pectin demethoxylase, pectin methoxylase, pectin methylesterase, pectase, pectin methylesterase, pectin 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-galacturonase, exo-D-galacturonanase, Exopoly-D-galacturonase, exo-poly-α-galacturonosidase, exopolygalacturonosidase, or exopolygalacturanosidase. The use of pectate lyases is particularly preferred.

[0069] 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 therefore belong to the third of the six main enzyme classes, the hydrolases (EC3.), among these to the glycosylases (EC 3.2.-.-) and again to the glycosidases (EC 3.2.1.-), i.e. enzymes that hydrolyze O- and / or S-glycosyl compounds. Pectinolytic enzymes therefore act in particular against residues on dishes that contain pectic acid and / or other galacturonans and catalyze their hydrolysis. Pectate lyases in the sense of the invention are enzymes that catalyze non-hydrolytic cleavage of pectate by an endo-mechanism.

[0070] 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.

[0071] As a preferred component, the detergent preparation contains 0.01 to 1% by weight, preferably 0.02 to 0.3% by weight of a mannanase preparation.

[0072] A mannanase catalyzes the hydrolysis of 1,4-ß-D-mannosidic bonds in mannans, galactomannans, glucomannans, and galactoglucomannans. These mannanases are classified as EC 3.2.1.78 according to enzyme nomenclature.

[0073] As a further preferred ingredient, the detergent preparations contain a cellulase preparation. Synonymous terms can be used for cellulases, in particular endoglucanase, endo-1,4-ß-glucanase, carboxymethylcellulase, endo-1,4-ß-D-glucanase, ß-1,4-glucanase, ß-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.

[0074] 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.

[0075] The weight proportion 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.%.

[0076] As a further optional ingredient, a preferred detergent preparation comprises 0.2 to 4 wt.%, preferably 0.5 to 3 wt.%, of a fragrance preparation. In addition to the actual fragrances, 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. In order to stimulate the sense of smell, the chemical substance should be at least partially dispersible in the air, i.e. the fragrance should be at least slightly volatile at 25°C. If the fragrance is very volatile, the odor intensity quickly fades away. With lower volatility, however, the odor impression is more lasting, i.e. it does not disappear as quickly. In one embodiment, the fragrance therefore has a melting point in the range from -100°C to 100°C, preferably from -80°C to 80°C, even more preferably from -20°C to 50°C, in particular from -30°C to 20°C. In a further embodiment, the fragrance has a boiling point in the range from 25°C to 400°C, preferably from 50°C to 380°C, more preferably from 75°C to 350°C, in particular from 100°C to 330°C.

[0078] Overall, a chemical substance should not exceed a certain molecular mass to function as a fragrance, since at too high a molecular mass, the required volatility can no longer be guaranteed. In one embodiment, the fragrance has a molecular mass of 40 to 700 g / mol, more preferably 60 to 400 g / mol.

[0079] The smell 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 also be used to mask unpleasant odors or to impart a desired scent to a non-odorous substance. Individual odorous compounds, such as synthetic products such as 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 referred to as a perfume or perfume oil. Such perfume oils can also contain natural fragrance mixtures, such as those obtainable from plant sources.

[0081] To prolong the fragrance effect, it has proven advantageous to encapsulate the fragrance. In one embodiment, at least part of the fragrance is used in encapsulated form (fragrance capsules), especially in microcapsules. However, the entire fragrance can also be used in encapsulated form. The microcapsules can be water-soluble and / or water-insoluble.

[0082] Fragrance capsules are typically characterized by a fragrance-containing core and a layer or shell surrounding this core. Capsules known to those skilled in the art can be used as fragrance capsules. The preferred group of fragrance capsules can be divided into two groups: Fragrance capsules selected from the group of melamine-urea-formaldehyde-containing fragrance capsules, melamine-formaldehyde-containing fragrance capsules, and urea-formaldehyde-containing fragrance capsules.

[0083] Biopolymer-containing fragrance capsules, in particular from the group of protein-containing fragrance capsules and polysaccharide-containing fragrance capsules, in particular gelatin-containing fragrance capsules, chitosan-containing fragrance capsules, starch-containing fragrance capsules and alginate-containing fragrance capsules.

[0100] Plasticizers that can be used include, for example, glycerin, ethylene glycol, diethylene glycol, propanediol, 2-methyl-1,3-propanediol, sorbitol or mixtures thereof.

[0101] To reduce its friction coefficient, the surface of the water-soluble film of the detergent dispenser can optionally be dusted with fine powder. Sodium aluminosilicate, silicon dioxide, talc, and amylose are examples of suitable powdering agents.
