Abstract

The present invention relates to washing and / or care articles comprising at least one propellant.

Description

The present invention relates to laundry and / or care articles which have at least one leavened agent. The invention further relates to the use of such articles for washing, cleaning and / or care purposes, preferably for washing, care or conditioning textiles, and to a method for washing, care or conditioning textiles using such an article.Although the main focus of consumers of fabric washing and care products is that the respective product has a sufficient cleaning and / or care effect on the fabrics to be washed, the demand for mono-dose detergents, i.e. detergents which are present in a unit dose and are accordingly easy to dose, simultaneously increases. Commercial dosage forms of such monodose detergents are, on the one hand, "laundry caps" and, on the other hand, "laundry sheets". However, both dosage forms each involve different disadvantages or do not satisfy the requirements placed on them in different ways. Although the cleaning performance of laundry detergent caps is generally satisfactory, they often only incompletely dissolve in the wash liquor, resulting in residues of the casing material both in the washing machine and on clothes washed with the caps. Since water-soluble laundry detergents are anhydrous, they are lasting, logistics-uncomplicated and, moreover, easy for consumers to handle. However, a comparatively low washing performance is felt to be disadvantageous here. There is therefore a continuing need for fabric washing and care compositions present in unit dosage form which are capable of overcoming the aforementioned disadvantages of commercially available products.This object is achieved by the use of leaveners in fabric washing and care products in fabric form ("laundry sheets"), since it has surprisingly been found that leaveners improve the effectiveness, in particular the cleaning performance, i.e. stain remover properties, of corresponding products. In addition, leaveners are also suitable for improving the solubility of such articles. In this way, not only residues are avoided, but it is also ensured that the active washing and / or care ingredients can rapidly transfer into the washing liquor and become effective.A first subject matter of the present invention is therefore a laundry and / or care article for textiles, comprising a substrate and at least one leavened agent.In a further aspect, the invention relates to the use of such a washing and / or care article for washing, cleaning and / or care purposes, preferably for washing, care or conditioning textiles.In a final aspect, the present invention also relates to a method for washing, caring for or conditioning textiles, characterized in that a washing and / or caring article as described herein is used in at least one method step.These and other aspects, features and advantages of the invention will become apparent to those skilled in the art from a study of the following detailed description and claims. Any feature of one aspect of the invention may be used in any other aspect of the invention.The term "textile treatment agent" as used herein denotes an agent which is used for textile treatment and, after the treatment has ended, causally leads to a change of at least one property of the textile selected from chemical, physical or aesthetic properties. In the context of the present invention, the constituents of a textile treatment agent can in principle be chosen and adapted such that the agent has the desired treatment properties, for example textile-cleaning, fabric-care, fabric-conditioning and / or fabric-protecting properties.The term "conditioning", in the context of the present invention, denotes imparting a desired property, for example, in terms of textiles, pleasant feel, crease-free or low static charge. A "fabric conditioning composition" as used herein is accordingly a composition which, when used in fabric washing and / or care processes, is intended to provide a pleasing feel, crease free or less static charge to the treated fabric.The subject matter of the invention includes all conceivable textile washing and / or care processes, on a commercial scale, in a washing machine or in hand washing. These include, for example, washing and cleaning methods and applications for cleaning, care and / or conditioning, pre- and / or post-treatment of all types of textiles, such as, for example, garments, carpets, and textile furniture surfaces."At least one" as used herein includes, but is not limited to, 1, 2, 3, 4, 5, 6, and more. With respect to an ingredient, the specification relates to the type of ingredient and not to the absolute number of molecules. "At least one surfactant" thus means, for example, at least one type of surfactant, i.e. that one type of surfactant or a mixture of a plurality of different surfactants can be meant. Together with weight data, the data refer to all compounds of the stated type which are contained in the composition / mixture, i.e. the composition does not contain any further compounds of this type beyond the stated amount of the corresponding compounds.All percentages are % by weight unless otherwise stated. Numerical ranges indicated in the format "from x to y" include the above values. When several preferred numerical ranges are specified in this format, it is understood that all ranges arising from the combination of the various endpoints are also detected."About" or "about" as used herein in connection with a numerical value refers to the numerical value ±10%, preferably ±5%.Whenever alkaline earth metals are mentioned below as counterions for monovalent anions, this means that the alkaline earth metal is naturally present only in half the amount of substance, which is sufficient for charge balancing, as the anion."Phosphate-free" and "phosphonate-free", as used herein, means that the composition in question is substantially free of phosphates or phosphonates, i.e. contains in particular phosphates or phosphonates in amounts of less than 0.1% by weight, preferably less than 0.01% by weight, based on the composition in question.A first subject matter of the present invention is a laundry and / or care article for textiles, comprising a substrate and at least one leavened agent.The washing and / or care article for textiles according to the invention is generally an article comprising a substrate which preferably has a planar shape.

However, it should be noted that in principle any dimension may be selected which appears advantageous for the respective intended use.The substrate constitutes a carrier or a matrix for the at least one blowing agent and optionally for further active substances and permits the metered addition of the at least one blowing agent and the optionally further active substances to the wash liquor. Preferred applications are fabric washing processes, especially in automatic washing machines.The term "leavener" as used herein also refers to compounds known in the art as "leavener". In principle, all types of such known biological and chemical back-up agent compounds are suitable. However, chemical blowing agents are preferred in the context of the present invention. Examples of such compounds include, but are not limited to, carbonates and hydrogen carbonates, in particular carbonates and hydrogen carbonates of alkali metals or alkaline earth metals, as well as ammonium (hydrogen) carbonate. Specific examples further include, but are not limited to, soda (sodium carbonate), soda (sodium hydrogen carbonate), cherry horny salt (substantially ammonium hydrogen carbonate) and potato pocket (potassium carbonate), as well as mixtures of the foregoing. It is likewise possible to use one or more of the aforementioned compounds from the group of carbonates or hydrogen carbonates in combination with an acidifying agent.

The composition can be applied to the substrate subsequently, for example by impregnation, spraying, doctoring or coating, or else constituents of the compositions are integrated into the substrate already during the production of the substrate, for example by deposition on the individual fibers or mixing with the components forming the film. Suitable components of such a composition may be selected, without limitation, from the aforementioned active categories. In various embodiments, the at least one leavener as defined and described above may be part of such a detergent or fabric conditioning composition.To improve the detergency, the article may comprise at least one surfactant. A surfactant in the sense of the present invention is a surface-active substance which, by micelle formation, is capable of dissolving dirt particles from the textile or textiles during a washing process with the respective washing agent.

The index m stands for an integer from 1 to 50, preferably from 1 to 20, and in particular from 2 to 10.According to a further advantageous development, in order to obtain a particularly good washing performance with a high soil release force, it is provided that a mass fraction of surfactant, based on the total mass of the article, is approximately 1 to 50% by weight and in particular approximately 3 to 25% by weight, for example approximately 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24 or 25% by weight. When using a combination of two or more surfactants, the proportion by mass relates to the total mass of the surfactants used.In various embodiments, a washing and / or care article according to the invention comprises at least one anionic surfactant, preferably in an amount of about 5 to 25 wt %, more preferably about 10 to 15 wt %, for example about 10, 10.5, 11, 11.5, 12, 12.5, 13, 13.5, 14, 14.5 or 15 wt %, in each case based on the total weight of the washing and / or care article.In various further embodiments, a washing and / or care article according to the invention comprises at least one non-ionic surfactant, preferably in an amount of about 0.1 to 20% by weight, more preferably about 1 to 10% by weight, for example about 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10% by weight, in each case based on the total weight of the washing and / or care article.Furthermore, in some embodiments, in particular when using water-insoluble substrates, the carrier substrate can have a dye-intercepting compound. For example, it may be coated or impregnated with a dye-trapping compound. If the substrate is a textile substrate, the dye scavenger, due to the absorbent properties of the textile material, is typically absorbed into or onto the textile carrier material, such as, for example, onto the individual fibers. Basically suitable ink-trapping coatings are known in the prior art. Suitable for this purpose are, for example, polyamines, N-trialkyl-substituted ammonium 2-hydroxy-3-halopropyl compounds or epoxide propyltrialkylammonium salts, for example GMAC (glycidyltrimethylammonium chloride) or precursors of GMAC such as 3-chloro-2-hydroxypropyltrimethylammonium chloride, and mixtures.Builders that may be present in the composition include, in particular, silicates, aluminum silicates (in particular zeolites), carbonates, salts of organic di- and polycarboxylic acids and mixtures of these substances.Organic builders are, for example, the polycarboxylic acids usable in the form of their sodium salts, polycarboxylic acids being understood to mean those carboxylic acids which carry more than one acid function. Examples of such acids are citric acid, adipic acid, succinic acid, glutaric acid, malic acid, tartaric acid, maleic acid, fumaric acid, saccharic acids, aminocarboxylic acids and mixtures thereof. Preferred salts are the salts of the polycarboxylic acid, citric acid, adipic acid, succinic acid, glutaric acid, tartaric acid, saccharic acids and mixtures thereof.Polymeric polycarboxylates are also suitable as builders.

The enzymes can also be present in the form of enzyme formulations which can furthermore comprise one or more organic solvents, preferably selected from alcohols, particularly preferably polyhydric alcohols which are liquid under standard conditions (20° C., 1013 mbar), in particular glycerol, 1,2-propanediol and sorbitol, and mixtures thereof, and / or enzyme stabilizers. Such an enzyme formulation may be present in the form of a slurry, preferably in the form of a pasty slurry. The term "slurry" in the context of the present invention denotes a liquid, enzyme-containing slurry.Enzymes can advantageously be used in amounts of from 0.0001 to 5% by weight, in particular in amounts of from 0.001 to 1.5% by weight, preferably in amounts of from 0.01 to 1.0% by weight, in each case based on the total weight of the washing and / or care article.As fragrances or fragrances or perfume oils, all substances and mixtures known for this can be used. For the purposes of this invention, the terms "perfume(s)", "perfumes" and "perfume oil(s)" are used interchangeably. This means in particular all those substances or mixtures thereof which are perceived as odour by humans and animals, in particular are perceived as pleasant odour by humans.Perfumes, perfume oils or perfume oil constituents can be used as perfume components. Perfume oils or fragrances can be individual perfume compounds according to the invention, for example the synthetic products of the ester, ether, aldehyde, ketone, alcohol and hydrocarbon type. All perfume compounds known from the prior art can be used. Mixtures of different fragrances are preferably used which together produce an appealing scent note. Such a mixture of fragrances can also be referred to as perfume or perfume oil. Such perfume oils may also contain natural perfume mixtures as are available from vegetable sources, for example essential oils.A perfume oil may also contain in the form of a perfume oil preparation and may comprise, for example, at least one further active in oil form. Suitable active substances in oil form in this context are those which are suitable for washing, cleaning, care and / or finishing purposes, in particular (a) textile care substances, such as preferably silicone oils, and / or (b) skin care substances, such as preferably vitamin E, natural oils and / or cosmetic oils.Skin care actives are all those actives that impart sensory and / or cosmetic benefit to the skin. Skin care active substances are preferably selected from the following substances: a) waxes such as carnauba, spermaceti, bees wax, lanolin and / or derivatives thereof and others. b) hydrophobic plant extracts c) hydrocarbons such as squalene and / or squalane d) higher fatty acids, preferably those with at least 12 carbon atoms, for example lauric acid, stearic acid, behenic acid, myristic acid, palmitic acid, oleic acid, linoleic acid, linolenic acid, isostearic acid and / or polyunsaturated fatty acids and others. e) higher fatty alcohols, preferably those with at least 12 carbon atoms, for example lauryl alcohol, cetyl alcohol, stearyl alcohol, oleyl alcohol, behenyl alcohol, Cholesterol and / or 2-hexadecanol and others. f) esters, preferably those such as cetyl octanoates, lauryl lactates, myristyl lactates, cetyl lactates, isopropyl myristates, myristyl myristates, isopropyl palmitates, isopropyl adipates, butyl stearates, decyl oleates, cholesterol isostearates, glycerol monostearates, glycerol distearates, glycerol tristearates, alkyl lactates, alkyl citrates and / or alkyl tartrates and others. g) lipids such as cholesterol, ceramides and / or sucrose esters and others. h) vitamins such as vitamins A, C and E, vitamin alkyl esters, including vitamin C alkyl esters and others. i) sunscreens j) phospholipids k) derivatives of alpha-hydroxy acids l) insecticides for cosmetic use, both synthetic such as salicylic acid and / or others and natural such as neem oil and / or other. m) silicones n) natural oils, e.g. almond oil and mixtures of any of the above components.It may be desirable to keep the active ingredients which positively influence the feel of the skin or else other sensitive active ingredients, for example perfumes or enzymes, spatially separate from further constituents of the composition until use. An elegant method for incorporating such sensitive, chemically or physically incompatible or volatile ingredients consists in the use of microcapsules in which these ingredients are enclosed in a storage- and transport-stable manner and from which they are released mechanically, chemically, thermally or enzymatically for or during use. In a preferred embodiment, therefore, one or more of the active ingredients and / or perfumes and / or fragrances and / or enzymes which positively influence the skin feel is incorporated completely or partially into microcapsules. The microcapsules used can be all surfactant-stable capsules and capsule materials available on the market or spheres and sphere materials.If appropriate, pH adjusters may also be present in order to impart the desired pH to the wash liquor when the washing or care composition according to the invention is used. Acids and / or alkalis are used as such. Suitable acids are, in particular, organic acids such as acetic acid, citric acid, glycolic acid, lactic acid, succinic acid, adipic acid, malic acid, tartaric acid and gluconic acid or else amidosulfonic acid. In addition, however, the mineral acids hydrochloric acid, sulfuric acid and nitric acid or mixtures thereof can also be used. Suitable bases are preferably from the group of the alkali and alkaline earth metal hydroxides and carbonates, in particular the alkali metal hydroxides, of which potassium hydroxide is preferred.

This is fixed on a KPG stirrer. The test sample is weighed, the mass is noted and dissolved at 800±10 rpm for 90±2 s. The solution is then filtered through a handwash test sieve of 0.2 mm mesh width and 70 mm diameter. In order to flush out any residues, up to 150 ml city water can be used for rinsing. The subsequent residue is weighed out and calculated according to the following equation as the percentage residue: A residue [%] F 1 mass of the empty sieve [g] F 2 mass of the sieve with the dried residue [g] E sample balance [g]An average of at least two determinations is to be calculated.Results of Solubility Test:(The lower the residue value, the more soluble the sheets)A.

Furthermore, residues of the sheets on the washed textiles are avoided and the overall washing result is improved.
