Description

The present invention relates to a surfactant and polymer-based, highly concentrated detergent preparation based on organic solvent carrier systems. Furthermore, the application relates to detergent portion units which comprise this detergent preparation and a method for washing textiles using the detergent preparation or the detergent portion unit.

Constantly changing requirements are placed on the packaging and supply forms of detergents and cleaning agents. For some time now, the main focus has been on the convenient dosing of detergents and cleaning agents by the consumer and the simplification of the work steps required to carry out a washing or cleaning process. A technical solution is offered by pre-portioned detergents or cleaning agents, for example foil bags with one or more receiving chambers for solid or liquid detergents or cleaning agents.

A trend that is relevant for the production of these foil bags is the miniaturization of these foil bags. The background to this development is greater consumer acceptance due to simplified handling, in particular sustainability aspects, for example in relation to transport volumes and costs and the amount of packaging used.

The concentration of modern detergents, in particular modern liquid detergents, generally influences their optical and rheological properties and also affects the storage stability of these detergents, especially when stored under stress conditions, i.e. above-average low or above-average temperatures.

The German patent application suggests improving the storage properties of concentrated liquid formulations DE 31 32 219 A1 propose the use of surfactant mixtures based on sulfobetaines and quaternary ammonium alkene sulfonates. In the German patent application DE 100 27 674 A1 describes the use of glyceride alkoxylates for the production of liquid detergents that are stable at low temperatures.

The application was based on the object of providing optically appealing, concentrated detergent portion units which can be produced in a simple and efficient manner, have good cleaning performance with small dosages and are optically, rheologically and chemically stable under demanding storage conditions.

   • a1) 10 to 30% by weight of nonionic surfactant from the group of alkyl ethoxylates and,
   • a2) 1 to 15 _wt g/mol, with alkylene oxides
   contains.

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

A first essential component of the detergent preparation is surfactant, which is present in the detergent preparation at 40 to 80% by weight, preferably at 50 to 75% by weight and in particular at 55 to 75% by weight.

The group of surfactants includes the nonionic, the anionic, the cationic and the amphoteric surfactants. The compositions according to the invention can comprise one or more of the surfactants mentioned. Particularly preferred compositions contain at least one anionic surfactant as the surfactant.

The anionic surfactant is preferably selected from the group consisting of C ₉ -C ₁₃ alkyl benzene sulfonates, olefin sulfonates, C ₁₂ -C ₁₈ alkane sulfonates, ester sulfonates, alk(en)yl sulfates, fatty alcohol ether sulfates and mixtures thereof. Compositions which comprise C ₉ -C ₁₃ -alkylbenzene sulfonates and fatty alcohol ether sulfates as anionic surfactants have particularly good dispersing properties. Surfactants of the sulfonate type are preferably C ₉ -C ₁₃ -alkylbenzene sulfonates, olefin sulfonates, i.e. mixtures of alkene and hydroxyalkane sulfonates and disulfonates, such as are obtained, for example, from C ₁₂ -C ₁₈ -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 C ₁₂ -C ₁₈ alkanesulfonates and the esters of α-sulfofatty acids (ester sulfonates), for example the α-sulfonated methyl esters of hydrogenated coconut, palm kernel or tallow fatty acids.

Alk(en)yl sulfates are the alkali and in particular the sodium salts of the sulfuric acid half esters of the C12-C18 fatty alcohols, for example from coconut fatty alcohol, tallow fatty alcohol, lauryl, myristyl, _cetyl or stearyl alcohol or the _C10 - _{C20 oxo} alcohols and those half esters of secondary alcohols of these chain lengths are preferred. C ₁₂ -C ₁₆ -alkyl sulfates and C ₁₂ -C ₁₅ -alkyl sulfates and also C ₁₄ -C ₁₅ -alkyl sulfates are preferred for reasons of washing technology. 2,3-Alkyl sulfates are also suitable anionic surfactants.

Preferred alk(en)yl sulfates are the salts of the sulfuric acid monoesters of fatty alcohols having 12 to 18 carbon atoms, for example from coconut fatty alcohol, tallow fatty alcohol, lauryl, myristyl, cetyl or stearyl alcohol or oxo alcohols having 10 to 20 carbon atoms and those half esters of secondary alcohols of these chain lengths are preferred. Alkyl sulfates having 12 to 16 carbon atoms and alkyl sulfates having 12 to 15 carbon atoms and alkyl sulfates having 14 and 15 carbon atoms are preferred for reasons of washing technology. 2,3-Alkyl sulfates are also suitable anionic surfactants.

Fatty alcohol ether sulfates, such as the sulfuric acid monoesters of the straight-chain or branched C ₇ -C ₂₁ alcohols ethoxylated with 1 to 6 moles of ethylene oxide, such as 2-methyl-branched C9-11 alcohols with an average of 3.5 moles of ethylene oxide (EO) or C12 18 fatty alcohols with 1 to 4 EO are suitable. Alkyl ether sulfates having the formula (A-1) are preferred

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

AO in formula (A-1) represents an ethylene oxide (EO) or propylene oxide (PO) group, preferably an ethylene oxide group. The index n of the formula (A-1) is an integer from 1 to 50, preferably from 1 to 20 and in particular from 2 to 10. n is very particularly preferably 2, 3, 4, 5, 6, 7 or 8. X is a monovalent cation or the nth part of an n-valent cation, preference being given to the alkali metal ions and including Na ⁺ or K ⁺ and the amines, with Na ⁺ and primary and secondary amines, in particular monoethanolamine, being extremely preferred. Further cations X ⁺ can be selected from NH4 ⁺ , ½ Zn ²⁺ , ½ Mg ²⁺ , ½ Ca ²⁺ , ½ Mn ²⁺ , and mixtures thereof.

Particularly preferred compositions contain an alkyl ether sulfate selected from fatty alcohol ether sulfates of formula (A-1) where R ¹ = linear C12-18 alkyl, n = 2, 3, 4, 5, 6, 7 or 8 and X ⁺ = Na ⁺ or HOCH _{2 CH2 NH3} ⁺ . Very particularly preferred representatives are Na fatty alcohol ether sulfates or monoethanolamine fatty alcohol sulfates having 12 to 18 carbon atoms and 2 EO (R ¹ =linear C12-18-alkyl, n=2 in formula A-1).

The degree of ethoxylation given represents a statistical average, which can be a whole or a fractional number for a specific product. The degrees of alkoxylation given represent statistical averages, which can be an integer or a fraction for a specific product. Preferred alkoxylates/ethoxylates have a narrow homolog distribution (narrow range ethoxylates, NRE).

In a particularly preferred embodiment, the composition contains C ₉ -C ₁₃ -alkyl benzene sulfonates and optionally additionally fatty alcohol ether sulfates as anionic surfactant.

R' und R" unabhängig H oder Alkyl sind und zusammen 9 bis 19, vorzugsweise 9 bis 15 und insbesondere 9 bis 13 C-Atome enthalten, und Y⁺ ein einwertiges Kation oder den n-ten Teil eines n-wertigen Kations (insbesondere Na⁺ oder HOCH₂CH₂NH₃ ⁺) bedeuten.It is very particularly preferred if the composition contains at least one anionic surfactant of the formula (A-2),

in the
R' and R" are independently H or alkyl and together contain 9 to 19, preferably 9 to 15 and in particular 9 to 13 carbon atoms, and Y ⁺ is a monovalent cation or the nth part of an n-valent cation (in particular Na ⁺ or HOCH ₂ CH ₂ NH ₃ ⁺ ).

In summary, preferred detergent preparations contain at least one anionic surfactant as a surfactant, preferably at least one anionic surfactant from the group consisting of C _8-18 alkyl benzene sulfonates, C _8-18 olefin sulfonates, C _12-18 alkane sulfonates, C _8-18 ester sulfonates, C _{8 -18} -alkyl sulfates, C _8-18 -alkenyl sulfates, fatty alcohol ether sulfates, in particular at least one anionic surfactant from the group of C _8-18 -alkylbenzenesulfonates.

The use of fatty acids has proven advantageous for stability and cleaning performance. 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 caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, oleic acid, linoleic acid and mixtures thereof. In the context of the application, the fatty acids are assigned to the group of anionic surfactants.

The proportion by weight of the anionic surfactant in the total weight of the detergent preparation is preferably 20 to 50% by weight and in particular 25 to 45% by weight.

The detergent preparations contain as a further essential component nonionic surfactant from the group of alkyl ethoxylates, which make up 10 to 30% by weight, preferably 15 to 30% by weight and in particular 20 to 30% by weight of the total weight of the detergent preparation.

Preferred alkyl ethoxylates are from the group of the ethoxylated primary C _8-18 alcohols, preferably the ethoxylated primary C _8-18 alcohols with a degree of alkoxylation ≥ 4, particularly preferably the C _12-14 alcohols with 4 EO or 7 EO, the C _9-11 alcohols with 7 EO, C _13-15 alcohols with 5 EO, 7 EO or 8 EO, C _13-15 oxo alcohols with 7 EO, C _12-18 alcohols with 5 EO or 7 EO EO, in particular the C _12-18 fatty alcohols with 7 EO or the C _13-15 oxo alcohols with 7 EO.

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

A third essential component of the detergent preparation is a specific polyalkoxylated amine with a proportion by weight of 0.5 to 10% by weight. Preferred detergent preparations contain, based on their total weight, 2 to 12% by weight, preferably 3 to 8% by weight, of polyalkoxylated amine. Corresponding proportions by weight have proven to be advantageous for the shelf life, but in particular for the cleaning performance.

Preferred polyalkoxylated amines have a weight-average molecular weight M _w 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, if applicable, for other polymers are weight-average molecular weights M _w , which can be determined in principle by means of gel permeation chromatography using an RI detector, with the measurement being advantageously carried out against an external standard.) in a known manner, 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, starting with an alkylene oxide, in particular selected 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, particularly preferably with propylene oxide. The polyalkoxylated amines obtainable in this way can be Trade block or random structures. Particular preference is given, inter alia, to a polyalkoxylated amine obtainable by propoxylation of triethanolamine, preferably with a length of the three side arms of 15 propylene oxide units each. Also preferred is a polyalkoxylated amine obtainable by propoxylation of triisopropanolamine, preferably with a length of the three side arms of 15 propylene oxide units each.

Preferred polyalkoxylated amines satisfy the general formula (I),

The detergent preparations according to the invention are based on an organic solvent system. The detergent preparation preferably contains, based on its total weight, 5 to 20% by weight, in particular 10 to 20% by weight, of organic solvent.

Preferred organic solvents are selected from the group 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, 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 of propanediol, glycerol, ethanol and mixtures thereof.

In addition to organic solvents, the detergent preparations can contain water as a further liquid carrier. The water content of preferred detergent preparations, based on their total weight, is less than 20% by weight, preferably from 1 to 15% by weight, in particular from 2 to 13% by weight and very particularly preferably from 6 to 13% by weight. .

Preferred detergent preparations have, based on their total weight, a total solvent content of 15 to 35% by weight, preferably 5 to 32% by weight and in particular 6 to 29% by weight.

Preferred detergent preparations contain an ethoxylated polyethylenimine. Preferred ethoxylated polyethylenimines are nonionic, ie they have no quaternary nitrogen atoms or ionic groups other than those which result from a pH-influenced protonation of the nitrogen atoms. The ethoxylated polyethyleneimine preferably comprises a polyethyleneimine backbone which has been modified by ethoxylation, the ethoxylated polyethyleneimine having a weight-average molecular weight M _w in the range from 300 g/mol to 10000 g/mol.

Preferred detergent preparations contain, as a further optional ingredient, 2 to 8% by weight, preferably 3 to 6% by weight, of enzyme preparation.

In addition to the actual enzyme protein, an enzyme preparation includes other components such as enzyme stabilizers, carrier materials or fillers. The enzyme protein usually makes up only a fraction of the total weight of the enzyme preparation. Preferably used enzyme preparations contain between 0.1 and 40% by weight, preferably between 0.2 and 30% by weight, more preferably between 0.4 and 20% by weight and most preferably between 0.8 and 10% by weight % of enzyme protein. In such compositions, an enzyme stabilizer can be included in an amount of 0.05 to 35% by weight, preferably 0.05 to 10% by weight, based on the total weight in the enzyme composition.

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. In this regard, the active protein concentration is determined by titrating the active centers using a suitable irreversible inhibitor (for proteases, for example phenylmethylsulfonyl fluoride (PMSF)) and determination of the residual activity (cf. M. Bender et al., J. Am. Chem. Soc. 88, 24 (1966), pp. 5890-5913 ).

As a further preferred optional ingredient, a preferred detergent composition comprises from 0.2% to 4% by weight, preferably from 0.5% to 3% by weight, of a perfume preparation.

In addition to the actual fragrances, the fragrance preparation includes, for example, solvents, solid carrier materials or stabilizers.

A fragrance is a chemical substance that stimulates the sense of smell. In order to be able to stimulate the sense of smell, the chemical substance should be at least partially airborne, i.e. the fragrance should be at least slightly volatile at 25°C. If the fragrance is now very volatile, the odor intensity then quickly fades away. With a 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, 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 which is 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.

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

The smell of a fragrance is perceived as pleasant by most people and often corresponds to the smell of, for example, blossoms, fruits, spices, bark, resin, leaves, grass, moss and roots. Fragrances can also be used to mask unpleasant odors or to provide a non-smelling substance with a desired smell. Individual fragrance compounds, for example synthetic products of the ester, ether, aldehyde, ketone, alcohol and hydrocarbon type, can be used as fragrances.

Mixtures of different fragrances are preferably used, which together produce an appealing fragrance. Such a mixture of fragrances can also be referred to as a perfume or perfume oil. Perfume oils of this kind can also contain natural mixtures of fragrances, such as are obtainable from vegetable sources.

To prolong the fragrance effect, it has proven advantageous to encapsulate the fragrance. In a corresponding embodiment, at least part of the fragrance is used in encapsulated form (fragrance capsules), in particular in microcapsules. However, the entire fragrance can also be used in encapsulated form. The microcapsules can be water-soluble and/or water-insoluble microcapsules. For example, melamine-urea-formaldehyde microcapsules, melamine-formaldehyde microcapsules, urea-formaldehyde microcapsules or starch microcapsules can be used. "Pro-fragrance" refers to compounds that only release the actual fragrance after chemical conversion/cleavage, typically upon exposure to light or other environmental conditions such as pH, temperature, etc. Such compounds are often also referred to as fragrance storage substances or “pro-fragrance”.

The substance systems described above are not only suitable for ensuring simple manufacturability, good shelf life and cleaning performance, but also enable the realization of a product appearance that is attractive to the consumer. Detergent preparations that are transparent and, for example, are perceived as visually attractive therefore have a low turbidity. Preferred detergent preparations therefore have a turbidity (HACH Turbidimeter 2100Q, 20° C., 10 ml cuvette) below 100 NTU, preferably below 50 NTU and in particular below 20 NTU. At an NTU value (at 20° C.) of 60 or more, moldings have a perceptible turbidity, which can be seen with the naked eye in the context of the invention.

Another group of detergent preparations that are perceived as visually attractive are the preparations with a cloudy white appearance. The turbidity (HACH Turbidimeter 2100Q, 20° C., 10 ml cuvette) of corresponding preferred detergent preparations is above 100 NTU and in particular above 400 NTU. Corresponding compositions preferably have an opacifying agent from the group of styrene-acrylate copolymers (INCI: styrene/acrylates copolymer) and inorganic salts, in particular from the group of inorganic salts.

Nephelometric Turbidity Unit (NTU) is a commonly used measure of transparency. It is a unit used, for example, in water treatment for turbidity measurements, e.g. in liquids. It is the unit of turbidity measured with a calibrated nephelometer. High NTU values are measured for opaque compositions while low values are determined for clear compositions.

The HACH Turbidimeter 2100Q turbidimeter from the Hach Company, Loveland, Colorado (USA) is used with the calibration substances StabICal Solution HACH (20 NTU), StabICal Solution HACH (100 NTU) and StabICal Solution HACH (800 NTU) , all of which can also be ordered from the Hach Company. The measurement is filled with the composition to be examined in a 10 ml measuring cuvette with a cap and the measurement is carried out at 20.degree.

The visual advantages of the concentrated detergent preparations come into their own in particular in packaging materials, which in turn are transparent and allow a direct view of the detergent composition. In addition to transparent plastic bottles, transparent bags, in particular water-soluble transparent bags, are therefore particularly preferred for assembly and packaging.

The viscosity (20° C., Brookfield DV-1 Prime viscometer with small sample adapter, spindle 31, 30 rpm in a 10 ml sample) of the detergent preparation is preferably in the range from 150 to 1200 mPas, preferably from 300 to 800 mPas.

1. i) eine erfindungsgemäße Waschmittelzubereitung
2. ii) einen wasserlöslichen Film, welcher die Waschmittelzubereitung vollständig umschließt.

A further preferred subject matter of this application is therefore a detergent portion unit

1. i) a detergent preparation according to the invention
2. ii) a water-soluble film which completely encloses the detergent preparation.

The water-soluble film in which the detergent composition is packaged may comprise one or more structurally distinct water-soluble polymer(s). Particularly suitable as water-soluble polymer(s) are polymers from the group of (possibly acetalized) polyvinyl alcohols (PVAL) and their copolymers.

Water-soluble films are preferably based on a polyvinyl alcohol or a polyvinyl alcohol copolymer whose molecular weight is in the range from 10,000 to 1,000,000 gmol ^-1 , preferably from 20,000 to 500,000 gmol ^-1 , particularly preferably from 30,000 to 100,000 gmol ^-1 and in particular from 40,000 to 80,000 gmol ^-1 lies.

The preparation of the polyvinyl alcohol and polyvinyl alcohol copolymers typically involves the hydrolysis of intermediate polyvinyl acetate. 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 in particular 82 to 88 mol %.

In addition to vinyl alcohol, preferred polyvinyl alcohol copolymers include an ethylenically unsaturated carboxylic acid, its salt or its ester. Such polyvinyl alcohol copolymers particularly preferably contain, in addition to vinyl alcohol, sulfonic acids such as 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS), acrylic acid, methacrylic acid, acrylic esters, methacrylic esters or mixtures thereof; among the esters, C _1-4 -alkyl esters or - hydroxyalkyl esters are preferred. Other suitable monomers are ethylenically unsaturated dicarboxylic acids, for example itaconic acid, maleic acid, fumaric acid and mixtures thereof.

Suitable water-soluble films for use are marketed, inter alia, by the company MonoSol LLC, for example under the designation M8630, M8720, M8310, C8400 or M8900. For example, films with the name ^Solublon® PT, ^Solublon® GA, ^Solublon® KC or ^Solublon® KL from Aicello Chemical Europe GmbH or the films VF-HP from Kuraray are also suitable.

The water-soluble films can contain additional active substances or fillers, but also plasticizers and/or solvents, in particular water, as further ingredients.

The group of further active ingredients includes, for example, materials which protect the ingredients of preparation (A) enclosed by the film material from decomposition or deactivation by exposure to light. Antioxidants, UV absorbers and fluorescent dyes have proven to be particularly suitable here.

For example, glycerol, ethylene glycol, diethylene glycol, propanediol, 2-methyl-1,3-propanediol, sorbitol or mixtures thereof can be used as plasticizers.

To reduce their coefficients of friction, the surface of the water-soluble film of the detergent portion unit can optionally be powdered with a fine powder. Sodium aluminosilicate, silica, talc and amylose are examples of suitable powdering agents.

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

The volume of the detergent portion unit is preferably from 10 to 35 ml, in particular from 12 to 18 ml.

Detergent portion unit according to one of the previous points, wherein the detergent portion unit has one to four receiving chambers, preferably three or four receiving chambers.
