EP4306625B1 - Concentrated washing agent composition with improved properties - Google Patents

Description

The present invention relates to a detergent portion unit based on a highly concentrated surfactant detergent preparation, in particular a detergent preparation containing 1,2 octanediol. The application also relates to methods for washing textiles using the detergent portion unit.

The packaging and supply of detergents and cleaning agents are subject to constantly changing requirements. 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. Pre-portioned detergents or cleaning agents offer a technical solution, for example foil bags with one or more compartments for solid or liquid detergents or cleaning agents.

A relevant trend for the production of these film bags is the miniaturization of these film bags. The background to this development is not only greater consumer acceptance due to easier handling, but also sustainability aspects, for example in relation to transport volumes and costs and the amount of packaging used.

The concentration of modern detergents, especially modern liquid detergents, generally influences their optical and rheological properties, has an impact on the storage stability of these agents and can influence their cleaning performance, especially if the high concentration of the active ingredients leads to incompatibilities.

The application was based on the task of providing visually appealing, concentrated, flowable detergent preparations which can be produced in a simple and efficient manner, have good storage properties and are characterized in particular by good cleaning results, in particular improved stain removal. Furthermore, the detergent preparation should be able to be packaged in water-soluble portion bags.

EP 0817881 B1 and EP 0227195 A2 describe cleaning compositions for stain removal, which contain 1,2 octanediol among other ingredients. EP 3974506 A1 , WO 2022/063499 A1 and WO 2017/216215 Detergent preparations are known.

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

Detergent preparations preferred on the basis of their washing performance contain, based on their total weight, 1 to 10% by weight, preferably 4 to 10% by weight, detergent-active polymer.

A first group of preferred detergent polymers are the polyalkoxylated polyalkyleneimines, which are obtainable by reacting polyalkyleneimines with alkylene oxides.

The N atoms in the polyalkyleneimine are preferably separated from one another by alkylene groups having 2 to 12 C atoms, in particular 2 to 6 C atoms, although not all alkylene groups must have the same number of carbon atoms. Particularly preferred are ethylene groups, 1,2-propylene groups, 1,3-propylene groups and mixtures thereof. The primary amino functions in the polyalkyleneimine can carry 1 or 2 polyalkoxy groups and the secondary amino functions 1 polyalkoxy group, although not every amino function has to be substituted by an alkoxy group. The average number of alkoxy groups per primary and secondary amino function in the polyalkoxylated polyalkyleneimine is preferably 5 to 100, in particular 10 to 50. The alkoxy groups in the polyalkoxylated polyalkyleneimine are preferably ethoxy, propoxy or butoxy groups or mixtures of these. Particularly preferred are polyethoxylated polyethyleneimines.

Finally, a fourth group of preferred detergent polymers are the ethylene oxide-propylene oxide-ethylene oxide triblock copolymers, wherein the copolymer comprises a first EO block, a second EO block and a PO block, wherein the first EO block and the second EO block are connected to the PO block.

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

In addition to the actual enzyme protein, an enzyme preparation comprises other components such as enzyme stabilizers, carrier materials or fillers. The enzyme protein usually only forms 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 the enzyme protein.

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 centers using a suitable irreversible inhibitor (for proteases, for example, phenylmethylsulfonyl fluoride (PMSF)) and determining the residual activity.

It is preferred if the detergent preparation contains at least one enzyme preparation, preferably at least 3 enzyme preparations of enzymes from the group amylase, protease, cellulase and mannanase.

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 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, as Keistase ^® . The α-amylase from B. amyloliquefaciens is sold by Novozymes under the name BAN ^® and derived variants of the α-amylase from B. stearothermophilus under the names BSG ^® and Novamyl ^® , also from Novozymes. Examples of α-amylases from other organisms are the further developments of the α-amylase from Aspergillus niger and A. oryzae, available under the trade names Fungamyl ^® from Novozymes.

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

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 means of hydrolysis. According to the invention, each of the enzymes from class EC 3.4 falls under this (comprising each of the thirteen subclasses falling under this). According to the invention, "protease activity" is present if the enzyme has proteolytic activity (EC 3.4). Various types of protease activity are known: The three main types are: trypsin-like, in which the amide substrate is cleaved after the amino acids Arg or Lys at P1; chymotrypsin-like, in which cleavage after one of the hydrophobic amino acids occurs at P1; and elastase-like, where cleavage of the amide substrate occurs after Ala at P1.

Surprisingly, it was found that a protease of the type of alkaline protease from Bacillus lentus DSM 5483 or a sufficiently similar protease (based on sequence identity) which has several of these changes in combination is particularly suitable for use in the detergent preparations according to the invention and is advantageously better stabilized therein. The advantages of using this protease therefore arise in particular with regard to washing performance and/or stability.

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

The weight proportion of the protease preparation in the total weight of the detergent preparation is preferably 0.2 to 3 wt.%, preferably 0.4 to 2 wt.%.

As a further preferred optional component, the detergent preparations contain a cellulase preparation. Synonymous terms can be used for cellulases, in particular endoglucanase, endo-1,4-beta-glucanase, carboxymethylcellulase, endo-1,4-beta-D-glucanase, beta-1,4-glucanase, beta-1,4-endoglucanhydrolase, celludextrinase or avicelase. The decisive factor as to 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.

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 the company 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 which can be used are Cellusoft ^® , Renozyme ^® and Celluclean ^® . Also usable are cellulases which are available from the company AB Enzymes, Finland, under the trade names Ecostone ^® and Biotouch ^® and which are based at least in part on the 20 kD EG from Melanocarpus.

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

As a preferred optional ingredient, the detergent preparation contains a phosphonate.

The weight proportion 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.%.

As a phosphonate compound, a phosphonate is preferably selected 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), in particular from the group of diethylenetriaminepentamethylenephosphonate (DTPMP).

As a further optional component, a preferred detergent preparation comprises 0.2 to 4% by weight, preferably 0.5 to 3% by weight, of fragrance 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 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 intensity of the smell will quickly fade. However, if the volatility is lower, the smell impression is more lasting, i.e. it does not disappear as quickly. In one embodiment, the fragrance therefore has a melting point that is in the range of -100°C to 100°C, preferably from -80°C to 80°C, even more preferably from -20°C to 50°C, in particular from -30°C to 20°C. In another 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 certain molecular mass in order to function as a fragrance, since if the molecular mass is too high, 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.

Most people find the smell of a fragrance pleasant and it often corresponds to the smell of flowers, fruits, spices, bark, resin, leaves, grass, mosses and roots. Fragrances can also be used to mask unpleasant smells or to give a non-smelling substance a desired smell. Individual fragrance compounds, e.g. synthetic products such as esters, ethers, aldehydes, ketones, alcohols and hydrocarbons, can be used as fragrances.

Preferably, mixtures of different fragrances are used, which together produce 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 available from plant 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. "Fragrance precursors" refer to compounds that only release the actual fragrance after chemical conversion/cleavage, typically through the action of light or other environmental conditions, such as pH value, temperature, etc. Such compounds are often also referred to as fragrance storage substances or "pro-fragrance".

The material systems described above are not only suitable for ensuring easy manufacture, good storage capacity and cleaning performance, but also enable the realization of a product appearance that is attractive to the consumer. For example, detergent preparations that are transparent and therefore have little turbidity are perceived as visually attractive. 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. With an NTU value (at 20°C) of 60 or more, molded bodies have a perceptible turbidity that is visible to the naked eye within the meaning of the invention.

The optical advantages of concentrated detergent preparations are particularly evident in packaging materials, which are themselves transparent and allow a direct view of the detergent composition. In addition to transparent plastic bottles, transparent bags, especially water-soluble transparent bags, are therefore preferred for assembly and packaging.

The water-soluble coating preferably comprises or consists of a film material. The film material can comprise one or more structurally different water-soluble polymer(s). Polymers from the group of (optionally acetalized) polyvinyl alcohols (PVAL) and their copolymers are particularly suitable as water-soluble polymer(s).

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 .

The preparation of polyvinyl alcohol and polyvinyl alcohol copolymers generally includes 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 comprise an ethylenically unsaturated carboxylic acid, its salt or its ester. In addition to vinyl alcohol, such polyvinyl alcohol copolymers particularly preferably contain sulfonic acids such as 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS), acrylic acid, methacrylic acid, acrylic acid esters, methacrylic acid esters or mixtures thereof; among the esters, 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 sold by MonoSol LLC, for example under the names M8630, M8720, M8310, C8400 or M8900. Also suitable are films with the names Solublon ^® PT, Solublon ^® GA, Solublon ^® KC or Solublon ^® KL from Aicello Chemical Europe GmbH or the VF-HP films from Kuraray.

The water-soluble films may contain additional active ingredients or fillers as well as plasticizers and/or solvents, in particular water.

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

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

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

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

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

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

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

In preferred process variants, the detergent preparation or the detergent portion unit is dosed directly into the drum or into the detergent drawer of the textile washing machine.

The machine textile washing process is preferably carried out at temperatures of 20°C to 60°C, preferably 30°C to 45°C. Preferred textile washing processes are used to clean cotton fabrics.
