Description

Perfumed solids

The present invention relates to particles which contain certain inorganic carrier material in a minimum amount of 30% by weight, perfume and nonionic surfactant (s) in amounts of at least 0.1% by weight, a process for producing such particles, a detergent composition containing such particles and a method for washing textiles with the aid of this detergent composition.

In textile washing, treatment and post-treatment, it is common today to add small amounts of perfume to the detergents and post-treatment agents, which serve to give the washing or rinsing solution itself, but also the textile goods treated with the washing or rinsing solution, a pleasant fragrance to lend. In addition to color and appearance, the scenting of detergents, cleaning agents and post-treatment agents is an important aspect of the aesthetic product impression and an important point in the consumer decision for or against a specific product. For scenting, the perfume can either be incorporated directly into the agents or added to the washing or rinsing solution in an additional step. The first way specifies a certain product characteristic, while the second way, the consumer can individually decide on "his" fragrance from the different fragrance options on offer, comparable to choosing an eau de toilette or an aftershave.

Accordingly, shaped fragrance articles and processes for scenting washing and rinsing liquors are widely described in the prior art. For example, DE 41 33 862 (Henkel) discloses tablets which contain carrier materials, fragrances and, if appropriate, further ingredients customary in washing and cleaning agents, sorbitol and additionally 20 to 70% by weight of a carbonate and acid bubbling system being used as carrier material. These tablets, which can be added, for example, to the rinse and fabric softener in a household washing machine, contain about 3 to 15, preferably 5 to 10,% by weight of fragrance. Due to the high disintegrant content of the tablets, they are sensitive to atmospheric moisture and must be stored appropriately protected. DE 39 11 363 (Baron Freytag von Loringhoven) discloses a process for producing a washing or rinsing liquor enriched with fragrance and a fragrance addition agent used for this purpose. The addition agents, which are in the form of capsules or tablets, contain the fragrance together with an emulsifier in liquid form (capsules) or bound to fillers and carriers (tablets), sodium aluminum silicates or cyclodextrins being mentioned as carriers. The fragrance content of the capsules or tablets is at least 1 g, the volume of the compositions being over 1 cm ³ . Tablets or capsules with more than 2.5 g of fragrance and a volume of at least 5 cm ³ are preferred. During storage, such tablets or capsules must be provided with a gastight and watertight coating in order to protect the ingredients. Further details on the production and the physical properties of suitable tablets are not contained in this publication.

The international application WO 94/25563 (Henkel-Ecolab) describes a process for the production of washing and cleaning-active moldings using microwave technology, which works without high pressure pressing. The molded articles produced in this way are distinguished by an extremely high dissolving speed or disintegration speed with simultaneous breaking strength, without the need for an explosive. At the same time, they are stable in storage and can be stored without additional precautions. In this way it is also possible to produce moldings which have a perfume oil content which is customary for detergents and cleaning agents and between 1 and 3% by weight. Perfume oils are generally volatile and could therefore evaporate under the influence of microwave radiation. If higher proportions of volatile liquid substances are to be used, a two-component system consisting of a component produced using microwave technology and a component containing the sensitive liquid substances is therefore described.

Particulate additives for scenting washing liquors and for use in detergents and cleaning agents and processes for their preparation are described in international patent applications WO97 / 29176 and WO97 / 29177 (Procter & Gamble). According to the teaching of these documents, porous carrier materials (for example sucrose in a mixture with zeolite X) are mixed with perfume and finally coated with a coating material (carbohydrates) and brought to the desired particle size distribution. German patent application DE 197 35 783 A1 (Henkel) describes high-dose perfume moldings which contain carrier material (s), 20 to 50% by weight of fragrance (s) and, if appropriate, other active substances and auxiliaries customary in washing and cleaning agents , wherein the moldings after deduction of the amount of fragrance at least 50 wt .-% of their weight consist of fatty acids and fatty acid salts. These perfume moldings are suitable for scenting detergents and cleaning agents as well as for scenting textiles in a washing machine.

A method for applying fragrances to textile goods in a washing machine is described in DE 195 30 999 (Henkel). In this method, a fragrance-containing molded body, which is produced by irradiation with microwaves, is used in the rinse cycle of a washing machine. According to the teaching of this document, the preferably spherical shaped bodies with diameters above 3 mm and bulk densities of up to 1100 g / l can be produced by filling a mixture of predominantly water-soluble carriers, hydrated substances, optional surfactants and perfume into suitable molds and with With the help of microwave radiation sinters. The fragrance contents of the shaped bodies are between 8 and 40% by weight, starches, silicas, silicates and disilicates, phosphates, zeolites, alkali salts of polycarboxylic acids, oxidation products of polyglucosans and polyaspartic acids are used as carriers. A prerequisite for the shaped body manufacturing process described in this document is that the mixture which is sintered into shaped bodies with the aid of microwave radiation has at least partially bound water, i.e. some of the starting materials are in hydrated form.

The proposed solutions mentioned in the prior art either require additional barrier layers or enveloping layers to fix the perfume on the carrier, or are not equally suitable for scenting detergents and cleaning agents and for direct use as the sole fragrance, for example for the rinse aid in one Washing machine suitable.

Against this background, it was an object of the present invention to provide a solid dosage form for fragrances which can carry larger amounts of fragrance and which can be incorporated into conventional washing and cleaning agents without a gas-tight coating layer. The invention relates to a particle which contains inorganic carrier material selected from the group comprising zeolites, sulfates, carbonates, silicates, silicic acid and / or mixtures thereof, and also perfume which is adsorbed on the carrier material and / or absorbed in the carrier material. the particles containing at least 0J% by weight of nonionic surfactant (s), based on the total particles.

The carrier material is preferably impregnated with the nonionic surfactant, i. H. the nonionic surfactant is advantageously essentially distributed in the carrier material and, in particular, essentially not enriched on the surface of the carrier material.

Surprisingly, a number of advantages have arisen through the subject of the invention. It has thus been found that the particles according to the invention, in comparison with corresponding particles without a nonionic surfactant, lead to a more intensive fragrance experience for the consumer, for example when washing laundry with a detergent formulation which contains the particles according to the invention. It has surprisingly been found that the consumer perceives a more intense scent of the washed laundry compared to laundry which was washed with a conventionally perfumed detergent formulation, even if the absolute amount of the perfume contained was the same. To this extent, the invention achieves a fragrance-enhancing effect which directly affects the particles, and objects into which these particles are incorporated, for example detergent formulations, and things such as B. Textiles, which are treated with the objects (here: detergent formulation).

Another advantage of the particles according to the invention is, surprisingly, that the perfume component incorporated in the particle is stabilized in comparison to an otherwise comparable particle in which no nonionic surfactant is contained. It is often the case that perfume, which is incorporated in a carrier material, at least partially decomposes more or less slowly in the carrier material. In contrast, this decomposition is at least delayed in a particle according to the invention. A perfume-stabilizing effect is thus achieved by the invention. This is especially true when the particle is incorporated into an object, such as. B. in a detergent formulation, which is rather detrimental to the stability of perfume due to its object property, for example its alkalinity. Here the perfume-stabilizing effect has a particularly favorable effect. Furthermore, it was surprisingly found that the scent impression resulting from the particles according to the invention lasts indirectly and immediately longer. "Immediate" in this context means that the particle according to the invention smells for a longer period than an otherwise comparable particle which, however, does not contain any nonionic surfactant, but does contain the same amount of perfume. "Indirect" in this context means that objects (e.g. Detergent formulation) which contain the particles according to the invention have a longer fragrance, and that even when these objects are used (for example detergent formulation for washing textile), the things treated with them (here: washed textile) have a longer fragrance.

The invention therefore achieves a fragrance (impression) with a sustained-release effect, this fragrance-retarding effect (ie the temporal expansion of the fragrance impression) both on the particles and on the objects containing particles and on those with them Related objects.

A great advantage of the invention is also surprisingly that the addition or the presence of nonionic surfactant makes it possible to load the carrier material of the particles with larger amounts of perfume. If there is no non-ionic surfactant, only smaller amounts of perfume can be absorbed. This is particularly surprising because it should be assumed that the amount of perfume that can be absorbed by the carrier material would have to decrease if the carrier material also has to absorb a certain amount of another substance. An improvement, in particular even a maximization of the perfume absorption capacity of the carrier material is thus achieved by the invention, so that perfume loading of the carrier material becomes possible to an extent which could not be achieved previously (in the absence of the nonionic surfactant).

The term perfume means perfume oils, fragrances and fragrances. Individual fragrance compounds, for example the synthetic products of the ester, ether, aldehyde, ketone, alcohol and hydrocarbon type, can be used as perfume oils or fragrances. Fragrance compounds of the ester type are, for example, benzyl acetate, phenoxyethyl isobutyrate, p-tert-butylcyclohexyl acetate, linalyl acetate, dimethylbenzylcarbinylacetate (DMBCA), phenylethyl acetate, benzyl acetate, ethylmethylphenylglycinate, allylcyclohexyl benzylsylatylalylate, methylateylalylate, methylatexylylalylate, methylate, methylate, methylate, methylate, cyclohexyl, methyll, benzylalylate, methylate, methyll, benzyl, The ethers include, for example, benzyl ethyl ether and ambroxan, the aldehydes, for example, the linear alkanals with 8-18 C atoms, citral, citronellal, citronel Lyloxy-acetaldehyde, cyclamenaldehyde, lilial and bourgeonal, the ketones, for example the jonones, oc-isomethylionone and methylcedryl ketone, the alcohols anethole, citronellol, eugenol, geraniol, linalool, phenylethyl alcohol and terpineol, the hydrocarbons mainly include the terpenes such as limonene and limonene pinene. However, preference is given to using mixtures of different fragrances which together produce an appealing fragrance.

Such perfume oils can also contain natural fragrance mixtures as are available from plant sources, e.g. Pine, citrus, jasmine, patchouly, rose or ylang-ylang oil. Also suitable are muscatel sage oil, chamomile oil, clove oil, lemon balm oil, mint oil, cinnamon leaf oil, linden blossom oil, juniper berry oil, vetiver oil, olibanum oil, galbanum oil and labdanum oil as well as orange blossom oil, neroliol, orange peel oil and sandalwood oil.

In order to be perceivable, a fragrance must be volatile, in addition to the nature of the functional groups and the structure of the chemical compound, the molar mass also plays an important role. Most odoriferous substances have molecular weights of up to about 200 daltons, while molecular weights of 300 daltons and more are an exception. Due to the different volatility of odoriferous substances, the smell of a perfume or fragrance composed of several odoriferous substances changes during evaporation, whereby the odor impressions are described in "top note", "heart or middle note" (middle note or body) and "base note" (end note or dry out). Since the smell is largely based on the intensity of the smell, the top note of a perfume or fragrance does not consist solely of volatile compounds, while the base note largely consists of less volatile , ie there are strong odoriferous substances.

Adhesive odoriferous substances which can advantageously be used in the context of the present invention are, for example, the essential oils such as angelica root oil, anise oil, arnica flower oil, basil oil, bay oil, bergamot oil, champagne flower oil, noble fir oil, noble pine cone oil, elemi oil, eucalyptus oil, fennel oil, fennel oil, fennel oil, fennel oil , Geranium oil, ginger grass oil, guaiac wood oil, gurjun balsam oil, helichrysum oil, ho oil, ginger oil, iris oil, kajeput oil, calamus oil, chamomile oil, camphor oil, kanaga oil, cardamom oil, cassia oil, chamomile oil, kola pomace oil, cumin oil, coriander oil, coriander oil, coriander oil, coriander oil, coriander oil - Del oil, lemongrass oil, lime oil, mandarin oil, lemon balm oil, musk grape oil, myrrh oil, Clove Oil, Neroli Oil, Niaouli Oil, Olibanum Oil, Orange Oil, Origanum Oil, Palmarosa Oil, Patchouli Oil, Peru Balsam Oil, Petitgrain Oil, Pepper Oil, Peppermint Oil, Allspice Oil, Pine Oil, Rose Oil, Rosemary Oil, Sandalwood Oil, Celery Oil, Spikja Oil, Star Anise Oil, Star Anise Oil, Thyme oil, verbena oil, vetiver oil, juniper berry oil, wormwood oil, wintergreen oil, ylang-ylang oil, hyssop oil, cinnamon oil, cinnamon leaf oil, lemon oil, lemon oil and cypress oil.

The more volatile fragrances which can be used advantageously in the context of the present invention include, in particular, the lower-boiling fragrances of natural or synthetic origin, which can be used alone or in mixtures. Examples of more volatile fragrances are alkyisothiocyanates (alkyl mustards), butanedione, limonene, linalool, linaylacetate and propionate, menthol, menthone, methyl-n-heptenone, phellandrene, phenylacetaldehyde, terpinylacetate, citral, citronellal. All of the aforementioned fragrances can be used alone or in a mixture according to the present invention with the advantages already mentioned.

The inorganic carrier material is selected from the group comprising zeolites, sulfates, carbonates, silicates, silicic acid and / or mixtures thereof. Preferred mixtures here are the following:

Zeolite sulfate, zeolite sulfate carbonate, zeolite sulfate carbonate silicate, zeolite sulfate carbonate silicate silicic acid, zeolite carbonate, zeolite carbonate silicate, zeolite carbonate silicate silicic acid, zeolite Silicate, zeolite-silicate-sulfate, zeolite-silicate-carbonate, zeolite-silicate-silica, zeolite-silica, zeolite-silica-sulfate, zeolite-silica-carbonate, sulfate-carbonate, sulfate-carbonate-silicate, sulfate- Carbonate-silicate-silica, sulfate-silicate, sulfate-silica, carbonate-silicate, carbonate-silica.

The (preferably finely crystalline, synthetic and bonded water-containing) zeolite is advantageously zeolite A and / or P. The zeolite P, zeolite MAP ^®, for example (commercial product of the company Crosfield) is used. Also, zeolite X and mixtures of A, X and / or P, for example, a co-crystal of zeolites A and X, the preferred are VEGOBOND ^® AX (commercial product of Condea Augusta SpA). The zeolite can preferably be used as a spray-dried powder or preferably also as an undried stabilized suspension which is still moist from its production. Y-type zeolite is also preferred.

The silicates, in particular amorphous silicates and crystalline layered silicates, are also preferred.

According to the invention. Support materials are in particular layered sodium silicates of the general formula NaMSi _x O _{2x + 1} ^' yH ₂ O, where M is sodium or hydrogen, x is a number from 1, 9 to 4 and y is a number from 0 to 20, and preferred values for x 2 , 3 or 4 are. Such crystalline layered silicates are described, for example, in European patent application EP-A-0 164 514. Preferred crystalline layered silicates of the formula given are those in which M represents sodium and x assumes the values 2 or 3. In particular, both β- and δ-sodium disilicates Na Si ₂ O ₅ ^• y H ₂ O are preferred. The preferred builder substances which can be used as carrier material also include amorphous sodium silicates with a modulus Na ₂ O: SiO ₂ of 1: 2 to 1: 3.3, preferably of 1: 2 to 1: 2.8 and in particular of 1: 2 to 1 : 2.6, which are delayed release and have secondary washing properties. The delay in dissolution compared to conventional amorphous sodium silicates can be caused in various ways, for example by surface treatment, compounding, compacting / compression or by overdrying. In the context of this invention, the term “amorphous” is also understood to mean “X-ray amorphous”. This means that the silicates in X-ray diffraction experiments do not provide sharp X-ray reflections, as are typical for crystalline substances, but at most one or more maxima of the scattered X-rays, which have a width of several degree units of the diffraction angle. However, it can very well lead to particularly good builder properties if the silicate particles provide washed-out or even sharp diffraction maxima in electron diffraction experiments. This is to be interpreted as meaning that the products have microcrystalline areas of size 10 to a few hundred nm, values up to max. 50 nm and in particular up to max. 20 nm are preferred. Such so-called X-ray amorphous silicates, which also have a delay in dissolution compared to conventional water glasses, are described, for example, in German patent application DE-A-44 00 024. Compacted / compacted amorphous silicates, compounded amorphous silicates and over-dried X-ray amorphous silicates are particularly preferred.

Suitable carrier materials are layered silicates of natural and synthetic origin. Layered silicates of this type are known, for example, from patent applications DE-B-23 34 899, EP-A-0 026 529 and DE-A-35 26 405. Their usability is not limited to a special composition or structural formula. However, smectites, in particular bentonites, are preferred here.

Layer silicates which can be used as carrier material and which belong to the group of water-swellable smectites are, for example, montmorrilonite, hectorite or saponite. In addition, small amounts of iron can be incorporated into the crystal lattice of the layered silicates according to the above formulas. Furthermore, due to their ion-exchanging properties, the layered silicates can contain hydrogen, alkali, alkaline earth ions, in particular Na ⁺ and Ca ²⁺ . The amount of water of hydration is usually in the range from 8 to 20% by weight and depends on the swelling condition or the type of processing. Layer silicates which can be used are, for example, from US Pat. No. 3,966,629, EP-A-0 026 529 and EP-A- 0 028432 known. Layered silicates are preferably used which are largely free of calcium ions and strongly coloring iron ions due to an alkali treatment.

According to a further preferred embodiment of the invention, alkoxylated alcohol is at least partially present as the nonionic surfactant, preferably in amounts of at least 40% by weight, advantageously of at least 50% by weight, in a further advantageous manner of at least 60% by weight extremely advantageously of at least 70% by weight, in an even more advantageous manner of at least 80% by weight, in particular of at least 90% by weight, in the most advantageous manner in amounts of 100% by weight, in each case based on the total amount Nonionic surfactant contained in the particle. If these are alkoxylated, advantageously ethoxylated, in particular primary alcohols having preferably 8 to 18, in particular 12 to 18, carbon atoms and preferably, on average, 1 to 12 moles of alkylene oxide, preferably ethylene oxide, per mole of alcohol, there is again a preferred embodiment of the invention in front.

Surprisingly, it was found that the alkoxylated alcohols in particular are very advantageous in order to maximize the perfume absorption capacity of the particles, to promote the stability of the perfume in the particles and to promote the fragrance retarding effect mentioned and the fragrance-enhancing effect.

According to a further preferred embodiment, the nonionic surfactants are a mixture of at least two different nonionic surfactants, preferably at least two different alkoxylated, advantageously ethoxylated, in particular primary alcohols, the distinguishing feature with respect to the alkoxylated alcohols preferably being the degree of alkoxylation ,

According to the invention, the carrier consists of the inorganic carrier material mentioned, it can consist of a single carrier material or can also be composed of several carrier materials. However, it is also possible that the carrier also contains other carriers in addition to the inorganic carrier materials according to the invention. Such further carriers are preferably in amounts of less than 50% by weight, advantageously less than 40% by weight, more advantageously less than 30% by weight, more advantageously in amounts less than 20% by weight, more advantageously Way in amounts less than 10 wt .-%, in an extremely advantageous manner in amounts less than 5 wt .-%, in particular in amounts less than 1 wt .-% (ie up to the extreme freedom from these other carriers) based on the total Contain carrier material (ie the sum of inorganic carrier material and further carrier material). Such other carriers are, preferably porous, solids, in particular selected from the group of surfactants, surfactant compounds, citrates, alkali metal phosphates, chitin microspheres, pectin, gums, gelatin, resins, starches, in particular porous starches, modified starches and / or carboxyalkyl starches, di- and / or polysaccharides, cyclodextrins, maltodextrins, (co) polymers, preferably synthetic (co) polymers, in particular water-soluble (co) polymers and / or terpolymers and mixtures thereof.

The carrier material can accordingly at least partially also include one or more (co) polymers as carrier, which are preferably at least partially selected from the following groups a) homopolymers selected from polyvinyl compounds such as preferably polyvinyl acetate, polyvinyl alcohol and / or polyvinylpyrrolidone, polycarboxy acids such as preferably Polyacrylic acid and / or polymethacrylic acid; Polysulfonic acids, such as preferably polystyrene sulfonic acids, polyesters, such as preferably glycol polyacrylates; Polyamides, polyacrylamides, polyurethanes, preferably polyurethanes, which carry ionic groups, for example carboxy groups, sulfonic acid groups or tertiary amines or polyurethanes, which preferably contain nonionic hydrophilic groups, such as ethylene oxide, polyethylene oxide, polypropylene oxide and polyalkylene glycol derivatives b) polycondensates, such as preferably ethoxylated.es Phenol, formaldehyde resins, preferably sulfonated aromatic formaldehyde resins, urea or melamines, formaldehyde compounds, polyamides, polyamines, and epichlorohydrin resins c) AB copolymers in which A represents a more water-soluble or water-swellable group and B represents a less water-soluble or water-swellable group, preferably selected from styrene copolymers, such as in particular styrene-acrylic acid polymers or styrene-ethylene oxide polymers, copolymer of polyvinyl and maleic acid compounds, such as preferably styrene-maleic anhydride polymers or vinyl acetates, maleic acid ester polymers, polyvinyl-polyalkylene copolymers, such as preferably vinyl acetate-ethylene polymers, ethylene-acrylic acid-acrylic acid ester polymers or ethylene-acrylic acid-acrylonitrile polymers Vinyl copolymers, such as preferably vinyl acetate polymers, acrylic acid-acrylonitrile polymers, acrylic acid-acrylamide polymers; d) ABA block copolymers where "A" stands for water-soluble or water-swellable groups, such as preferably polyethylene oxide, polyvinyl alcohol, polyacrylamide, polyacrylic acid, polyvinylpyrrolidone, or polycaprolactone and "B" for less water-soluble or hardly water-soluble groups, such as preferably polypropylene oxide, polyvinyl acetate, polyvinyl butyral , Polylauryl methacrylate, polystyrene, polyhydroxystearic acid, polysiloxanes, e) AB graft (co) polymers, where "A" is water-soluble or water-swellable groups such as preferably vinyl alcohol, vinyl acetate, ethylene oxide, propylene oxides, vinyl sulfonates, acrylic acids and vinylamines, "B "is preferably selected from vinyl polymer or siloxane. f) Natural polymers such as preferably cellulose derivatives, such as in particular carboxymethyl cellulose, hydroxypropyl methyl cellulose, methyl cellulose and / or their derivatives.

Particular mention should be made of polymers which preferably contain at least some of the monomers selected from isobutyl methacrylate, n-butyl acrylate, n-butyl methacrylate, isobutyl acrylate, n-propyl acrylate, isopropyl methacrylate, methyl methacrylate, styrene, decyl (meth) acrylate, Dodecyl (meth) acrylate, tetradecyl (meth) acrylate and / or hexadecyl (meth) acrylate and mixtures thereof.

Nevertheless, the inorganic carrier material is particularly preferred, and if the inorganic carrier material is at least 40% by weight, preferably at least 50% by weight, advantageously at least 60% by weight, in a further advantageous manner at least 70% by weight , in an advantageous manner at least 80% by weight, in an even more advantageous manner at least 90% by weight, in particular completely consists of zeolite, Zeolite X, Y, A, P, MAP and / or mixtures thereof, this is a preferred embodiment of the invention.

The zeolite should preferably contain less than 15% by weight, advantageously less than 8% by weight, in particular less than 5% by weight, of desorbable water. Such zeolite can be obtained, for example, by activating or dehydrating the zeolite at temperatures from 150 ° C. to 350 ° C., possibly under reduced pressure (advantageously from approximately 0.001 to approximately 20 torr). Then one speaks of activated / dehydrated zeolite.

The carrier material can at least partially also contain surfactant carrier in addition to the nonionic surfactant present according to the invention. All surfactants or surfactant compounds that are solid at temperatures up to 40 ° C. can be used as surfactant carriers. In the context of the present invention, the term "surfactant compound" is understood to mean a surfactant-containing preparation which contains at least 20% by weight of a preferably anionic surfactant, based on the surfactant compound. The carriers which are usually further contained in the surfactant compounds are preferably identical to those aforementioned carriers according to the invention.

One or more anionic surfactant compounds or anionic surfactants, in particular soaps, can therefore also be contained in the carrier material as carrier. Examples of anionic surfactant compounds are alkylbenzenesulfonate (ABS) compounds on silicate or zeolite supports with ABS contents of, for example, 10, 15, 20 or 30% by weight, fatty alcohol sulfate (FAS) compounds on silicate, zeolite or sodium sulfate carriers with active substance contents of, for example, 50-70, 80 or 90% by weight and compounds containing anionic surfactants based on sodium carbonate / sodium silicate with anionic surfactant contents above 40% by weight.

The pure anionic surfactants can also be included in the carrier material as carrier in the context of the present invention, provided that they are solid and their use is not prohibited because of possible hygroscopicity. Soaps in particular are preferred as purely anio-surfactant carriers, since on the one hand they can remain solid up to high temperatures and on the other hand they do not cause any problems with regard to unwanted water absorption. All salts of fatty acids are used as soaps. While in principle, for example, aluminum, alkaline earth metal and alkali metal salts of the fatty acids can be used, those are preferred in which the alkali metal and, in turn, the sodium salts of the fatty acids are preferably contained. As Fatty acids, the salts of which may be contained in the carrier material as carrier, are suitable for all acids obtained from vegetable or animal oils and fats. The fatty acids can be saturated or mono- to polyunsaturated. Of course, not only can "pure" fatty acids be included, but also the technical fatty acid mixtures obtained from the splitting of fats and oils, for example palm kernel, coconut, peanut or rapeseed oil or beef tallow, these mixtures again being clearly preferred from an economic point of view are.

For example, individual species or mixtures of the salts of the following acids can be used in the carrier material: caprylic acid, pelargonic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, octadecan-12-ol-acid, arachic acid, behenic acid, lignoceric acid, cerotic acid, melissic acid, 10- Undecenoic acid, petroselinic acid, petroselaidic acid, oleic acid, elaidic acid, ricinoleic acid, linolaidic acid, gadoleic acid, erucic acid, brassidic acid can be included as carriers. Of course, the salts of fatty acids with an odd number of carbon atoms can also be used, for example the salts of undecanoic acid, tridecanoic acid, pentadecanoic acid, heptadecanoic acid, nonadecanoic acid, heneicosanoic acid, tricosanoic acid, pentacosanoic acid, heptacosanoic acid.

One or more substances from the group of the sodium salts of saturated or unsaturated C ₈ can also be used as carrier (s). , Preferably from saturated or unsaturated C _{12 24} fatty acids - be comprised ₁₈ fatty acids and in particular saturated or unsaturated C ₁₆ fatty acids in the carrier material.

Other suitable carriers which can be included in the carrier material are, for example, di- and polysaccharides, a wide range of substances being able to be used, from sucrose and maltose to oligosaccharides to the “classic” polysaccharides such as cellulose and starch and their derivatives Among the substances from this subgroup, the strengths are again particularly preferred.

Usable and preferred organic carriers which may be present in the carrier material are, for example, the polycarbonic acids which can be used in the form of their sodium salts, such as citric acid, adipic acid, succinic acid, glutaric acid, tartaric acid, sugar acids, aminocarboxylic acids, nitrilotriacetic acid (NTA), provided that such use is appropriate ecological reasons are not objectionable, as well as mixtures of these. Before- drawn salts are the salts of polycarboxylic acids such as citric acid, adipic acid, succinic acid, glutaric acid, tartaric acid, sugar acids and mixtures of these.

The acids themselves can also be included as a carrier in the carrier material. In addition to their property as a carrier substance, the acids typically also have the property of an acidifying component and thus also serve to establish a lower and milder pH, for example of detergents and cleaning agents. Citric acid, succinic acid, glutaric acid, adipic acid, gluconic acid and any mixtures of these should be mentioned in particular. These acids are preferably used in anhydrous form.

Polymeric polycarboxylates can also be included in the carrier material as carrier, for example the alkali metal salts of polyacrylic acid or polymethacrylic acid, for example those with a relative molecular weight of 500 to 70,000 g / mol. In the context of this document, the molecular weights given for polymeric polycarboxylates are weight-average molecular weights M _{w of} the particular acid form, which were determined in principle by means of gel permeation chromatography (GPC), a UV detector being used. The measurement was carried out against an external polyacrylic acid standard, which provides realistic molecular weight values due to its structural relationship to the polymers investigated. This information differs significantly from the molecular weight information for which polystyrene sulfonic acids are used as standard. The molecular weights measured against polystyrene sulfonic acids are generally significantly higher than the molecular weights given in this document.

It is advantageous for the carrier material to be able to absorb the perfume if the carrier material is porous, preferably has a pore structure.

According to a further preferred embodiment, the pore size of the carrier material is essentially at least 6 angstroms, preferably it is essentially in the range from 7 to 50 angstroms, so that at least 40%, advantageously at least 50%, in further advantageously at least 60%, still more advantageously at least 70%, preferably at least 80%, in particular 90% of the pores of the carrier material meet this pore size requirement.

If this pore size criterion is met, there is a more advantageous incorporation of the perfume into the pores of the carrier material. If the pore volume of the carrier material is at least 0.1 ml / g, preferably at least 0.2 ml / g, in particular does not exceed a value of 2.5 ml / g, there is also a preferred embodiment of the invention.

According to a further preferred embodiment, the carrier material has a hygroscopicity value of less than 80%, preferably less than 50%, in particular less than 30%.

The hygroscopicity value is the degree of moisture absorption, which corresponds to the weight gain of the particles using the following test method. The hygroscopicity value is determined by placing 2 grams of the particles in a 50 ml beaker and storing it at 80% relative humidity and 32 ° C. The weight increase of the particles in percent based on the initial weight corresponds to the hygroscopicity value in percent.

If, in addition to perfume and nonionic surfactant (s), the carrier material contains at least one further component, preferably selected from bleach, bleach activator, bleach catalyst, chelating agent, threshold inhibitor, color transfer inhibitor, photobleach, enzymes, softener, pH adjusting agent, there is likewise a preferred embodiment ,

According to a further preferred embodiment, the carrier contains less than 15% by weight, preferably less than 8% by weight, in particular less than 5% by weight, of absorbable water.

If the particle size of the individual particles is essentially between 0.005 and 1.0 mm, it is a further preferred embodiment of the invention. The expression "essentially" here means that at least 40% by weight, advantageously at least 50% by weight, more advantageously at least 60% by weight, more advantageously at least 70% by weight, preferably at least 80% by weight .-%, in particular 90 wt .-% of the particles meet this particle size requirement.

If the particles according to the invention are agglomerated, the agglomerate size preferably being essentially 100-2000 μm, in particular essentially 100-800 μm, there is again a preferred embodiment of the invention. The expression "essentially" here means that at least 40% by weight, advantageously at least 50% by weight, more advantageously at least 60% by weight, more advantageously at least 70% by weight, preferably at least 80% by weight .-%, in particular 90% by weight of agglomerates have the agglomerate size mentioned. Upon contact with water, these agglomerated particles preferably disintegrate again into the smaller primary particles from which the agglomerates are / were composed. In some cases, the agglomerate size can even be in the range of 0.1 to 30 mm, if this is desired from an application point of view.

If the boiling points of the individual fragrances which are ad / absorbed on / in the carrier material are essentially below 300 ° C., there is a preferred embodiment of the invention, preferably at least 50% of the fragrances contained having a boiling point below 300 ° C., advantageously at least 60%, in a further advantageous manner at least 70%, in an even more advantageous manner at least 80%, in an extremely advantageous manner at least 90%, in particular even 100%.

Boiling points below 300 ° C are advantageous because the fragrances in question would have too little volatility at higher boiling points. However, in order to be able to at least partially "flow" out of the particle and develop a fragrance, a certain volatility of the fragrances is advantageous.

It has previously been observed that some unstable perfume ingredients are sometimes not well compatible with carrier material and at least partially decompose after incorporation in the carrier, especially if the carrier is a porous mineral carrier such as clay or zeolite, especially dehydrated and / or activated zeolite. Unstable fragrances in the sense of this invention can be identified by incorporating a perfume composition comprising at least 6 fragrances in activated / dehydrated zeolite X and storing the resulting sample for 24 hours at room temperature. The fragrances are then extracted with acetone and analyzed by gas chromatography to determine the stability. A fragrance is considered to be unstable in the sense of this invention if at least 50% by weight, preferably at least 65% by weight, advantageously at least 80% by weight, in particular at least 95% by weight, of this fragrance has decomposed into degradation products and cannot be recovered during the extraction.

The inventive composition contains less than 15% by weight, preferably less than 8% by weight, advantageously less than 6% by weight, even more advantageously less than 3% by weight, of the unstable perfume, based on the total A quantity of perfume which is ad / absorbed in / on the particle is a preferred embodiment of the The invention above, wherein the unstable perfume comprises in particular the group of allyl alcohol esters, esters of secondary alcohols, esters of tertiary alcohols, allylic ketones, condensation products of amines and aldehydes, acetals, ketals and mixtures of the aforementioned.

If the perfume which is ad / absorbed in / on the particle is at least 4, advantageously at least 5, in a further advantageous manner at least 6, in a further advantageous manner at least 7, in an even more advantageous manner at least 8, preferably at least 9, in particular at least Contains 10 different fragrances, there is a preferred embodiment of the invention.

If the logP value of the perfume components which are adsorbed / absorbed in / on the particle is essentially at least 2, preferably at least 3 or greater, so that at least 40%, advantageously at least 50%, in further advantageously at least 60%, In a more advantageous manner, at least 70%, preferably at least 80%, in particular 90% of the perfume components meet this log requirement, this is a preferred embodiment of the invention.

The logP value is a measure of the hydrophobicity of the perfume components. It is the decimal logarithm of the partition coefficient between n-octanol and water. The octanol / water partition coefficient of a perfume ingredient is the ratio between its equilibrium concentrations in water and octanol. A perfume ingredient with a higher partition coefficient P is more hydrophobic. The conditions mentioned for the logP are advantageous because this ensures that the fragrances can be better retained in the pores of the carrier material and also better on objects which are treated with the particles (for example indirectly by treatment with a detergent formulation, which contains the particles according to the invention). The logP of many perfume ingredients is given in the literature; for example, the Pomona 92 database, available from Daylight Chemical Information Systems, Inc. (Daylog CIS), Irvine, California, contains many such values along with references to the original literature. The logP values can also be calculated, for example using the “CLOG P” program from the company Daylight CIS just mentioned. In the case of calculated logP values, one generally speaks of ClogP values. Within the scope of this invention, the term logP -Values also include the clog-P values. Preferably, clog-P values should then be used for hydro- Phobicity assessment can be used if there are no experimental logP values for certain perfume ingredients.

If desired, the perfume can also be combined with a perfume fixative. It is believed that perfume fixatives can slow the evaporation of the more volatile parts of perfumes.

According to a further preferred embodiment, the perfume which is adsorbed in / on the carrier material comprises a perfume fixative, preferably in the form of diethyl phthalates, musk (derivatives) and mixtures thereof, the amount of fixative preferably being 1 to 55% by weight. , advantageously 2 to 50% by weight, more advantageously 10 to 45% by weight, in particular 20 to 40% by weight of the total amount of perfume.

According to a further preferred embodiment, the particles contain a viscosity-increasing liquid, in particular a perfume, preferably PEG (polyethylene glycol), advantageously with a molecular weight of 400 to 2000, the viscosity-increasing agent preferably in amounts of 0J to 20 % By weight, advantageously from 0.15 to 10% by weight, more advantageously from 0.2 to 5% by weight, in particular from 0.25 to 3% by weight, based on the particles ,

It has been found that the viscosity of liquids, in particular of perfume-increasing agents, make a further contribution to stabilizing the perfume in the particles if nonionic surfactant is present at the same time.

The viscosity-increasing agents are preferably polyethylene glycols (short: PEG), which can be described by the general formula I:

H- (O-CH ₂ -CH ₂ ) _n -OH (I),

in the degree of polymerization n can vary from about 5 to> 100,000, corresponding to molecular weights from 200 to 5,000,000 gmol ^"1. The products with molecular weights below 25,000 gmol ^{" 1} are referred to as the actual polyethylene glycols, whereas higher molecular weight products in the literature are often referred to as polyethylene oxides (short: PEOX). The preferably used polyethylene glycols can have a linear or branched structure, linear polyethylene glycols being preferred in particular, and being end group-capped. The particularly preferred polyethylene glycols include those with relative molecular weights between 400 and 2000. In particular, polyethylene glycols which are in the liquid state at room temperature and a pressure of 1 bar can also be used; here we are mainly talking about polyethylene glycol with a relative molecular mass of 200, 400 and 600.

According to a further preferred embodiment of the invention, the carrier material or the particles is at least partially surrounded by a coating which preferably contains at least one at least partially water-soluble or at least partially water-dispersible component, which is selected in particular from polyols, carbohydrates, starches, modified Starches, starch hydrolysates, cellulose and cellulose derivatives, natural and synthetic gums, silicates, borates, phosphates, chitin and chitosan, water-soluble polymers, fat components and mixtures of these. For example, waxes and / or resins are also possible, e.g. B. beeswax, benzoin, camauba wax, candelilla wax, coumarone-indene resin, copale, shellac, mastic, polyethylene wax oxidate or sandarak resin. Paraffins or gelatin, in particular cellulose ethers, are also suitable.

According to a further preferred embodiment, the coating has polycarboxylates.

The coating of the particles can be carried out in the ways described in the prior art. The coating material preferably completely surrounds the respective particles, although an incoherent coating may also be desirable. The most suitable coating materials are those which are commonly used in connection with detergents and cleaning agents.

Materials which can be used as coating materials in the sense of the invention are any inorganic and / or organic substances and / or substance mixtures, preferably those which are sensitive to pH, temperature and / or ionic strength, so that they are dependent on a pH , Temperature and / or ionic strength change lose their integrity, ie dissolve completely or partially, for example.

Polymers and / or copolymers which have film-forming properties and can preferably be used from aqueous dispersion are particularly preferred as coating materials. Organic solvents are disadvantageous for many reasons (flammability, toxicity, etc.) in the production of pH-sensitive coatings. Wäß- Dispersions are characterized by easy handling and the avoidance of all toxicological problems. The decisive parameter for the film-forming properties is the glass transition temperature of the film-forming polymer and / or copolymer. Above the glass transition temperature, the polymer or copolymer is elastic, meltable and flowable, while below the glass transition temperature it becomes brittle. Only above the glass transition temperature can the polymer be easily processed, as is required to form a film coating. The glass transition temperature can be influenced by the addition of low-molecular substances with softening properties, the so-called plasticizers. In addition to the polymer, plasticizers can also be used in the aqueous dispersion. All substances which lower the glass transition temperature of the preferably pH-sensitive polymers and / or copolymers used are suitable as plasticizers. The polymer can thus be applied at lower temperatures, possibly even at room temperature. Particularly preferred plasticizers are citric acid esters (preferably tributyl citrate and / or triethyl citrate), phthalic acid esters (preferably dimethyl phthalate, diethyl phthalate and / or dibutyl phthalate), esters of organic polyalcohols (preferably glycerol triacetate), polyalcohols (preferably glycerol, propylene glycol) and / or Polyoxyethylene glycols (preferably polyethylene glycol). The plasticizer is stored between the polymer chains, thereby increasing mobility, reducing interactions and preventing abrasion and cracks in the film by reducing the brittleness.

It is particularly advantageous if the coating material contains a polyacrylate and / or a derivative thereof and / or a corresponding copolymer based on acrylic acid esters or acrylic acids and other monomers. Copolymers of acrylamide and acrylic acid and / or their derivatives are particularly advantageous for the coating material according to the invention.

If the carrier material or the particles at least partially has a coating which comprises an at least partially water-soluble or at least partially water-dispersible component which comprises 0% by weight to 80% by weight of at least one solid polyol with preferably more than 3 hydroxyl radicals and from 20% to 100% by weight of a liquid diol or polyol in which the perfume is substantially insoluble and in which the solid polyol is substantially soluble, said liquid polyol or diol preferably from glycerin , Ethylene glycol and diglycerin or mixtures thereof and in which the solid polyol is preferably selected from glucose, sorbitol, maltose, glucamine, sucrose, polyvinyl alcohol, starch, Al- kylpolyglycosid, sorbitan fatty esters, polyhydroxy fatty acid amides, the fatty acid residues of which contain 1 to 18 carbon atoms, and mixtures thereof, a further preferred embodiment of the invention is present.

According to a preferred embodiment, the particles according to the invention contain a) inorganic carrier material in amounts from 50 to 95% by weight, preferably 60 to 90% by weight b) Perfume in amounts from 0.5 to 40% by weight, preferably from 1 to 35% by weight c) nonionic surfactant in amounts of 0.1 to 30% by weight, preferably 0.5 to 10% by weight, in particular 1 to 5% by weight d) auxiliaries in amounts of 0 up to 15% by weight, preferably from 0.5 to 10% by weight, advantageously from 0.75% by weight to 7.5% by weight, in particular from 1 to 5% by weight.

The auxiliaries are preferably polymeric substances such as carboxymethyl cellulose, polyacrylates, polycarboxylates and generally carriers which do not belong to the inorganic carriers according to the invention.

Another object of this invention is a method for producing a particle according to the invention comprising a) the provision of the carrier material according to the invention, preferably based on aqueous suspensions of inorganic and organic constituents, which advantageously comprise nonionic surfactant, the aqueous suspensions then being dried, then b) optionally impregnating the carrier material according to the invention with at least one nonionic surfactant, and c) loading the carrier material with perfume by mixing perfume and (impregnated) carrier material and / or by spraying perfume onto the (impregnated) carrier material, and

optionally the coating of the scented carrier material.

According to process step a), the carrier material according to the invention is provided, preferably on the basis of aqueous suspensions of inorganic and organic constituents, which advantageously comprise nonionic surfactant, the aqueous suspensions are then dried. A carrier material which contains nonionic surfactant during manufacture is therefore preferably used.

It is particularly preferred here if carbon dioxide is generated in the drying material during the drying of the aqueous suspension.

In the broadest sense, drying means any technical drying option with which water and / or other solvents can be largely removed from the aqueous suspensions so that at the end of the drying process, particles, i.e. there are particulate solids that form the desired carrier material. Of course, these particles do not have to be completely solvent-free and / or water-free, for example they can still contain significant amounts of solvent and / or water, but they preferably have water components below 30% by weight, advantageously below 25% by weight, in particular below 20% by weight .-%, based in each case on the solid obtained at the end of drying. If desired, the water content can also be lower, for example below 15% by weight or below 10% by weight or below 5% by weight, in each case based on the solid obtained at the end of drying.

For drying, heat is advantageously added to the material to be dried. Drying can preferably be carried out in cocurrent, countercurrent or crossflow. A distinction is made between contact dryers, convection dryers and radiation dryers according to the type of heat supply. Depending on the pressure in the dryer, it can be divided into overpressure, normal pressure and vacuum dryers. In convection drying, the heat is transferred to the material to be dried mainly by hot gases (air or inert gas), which is preferred. Channel, chamber, belt, shaft, fluidized bed and atomization dryers are used for this, which is preferred. In the case of contact drying, which is also preferred, the heat is transferred via heat exchanger surfaces. Contact dryers include roller, tube and cabinet dryers. Floor, plate, drum and paddle dryers work according to both principles of heat supply.

A drying process which is very preferred according to the invention is spray drying. Fluidized bed processes are also preferred for drying.

According to a preferred embodiment of the invention, the aqueous suspension to be dried according to the invention contains substance (s) which, at elevated temperatures, contain carbon. Release oil dioxide, preferably selected from hydrogen carbonate compounds, citric acid and / or aconitic acid. For the bicarbonate compounds, sodium bicarbonate is preferred.

According to a further preferred embodiment of the invention, the aqueous suspension to be dried according to the invention contains 0 to 40% by weight, preferably 0.1 to 4% by weight, in particular 1 to 3% by weight of citric acid, or 0 to 50% by weight. %, preferably 0J to 5% by weight, in particular 1 to 4% by weight of hydrogen carbonate compound, or 0 to 40% by weight, preferably 0J to 10% by weight, in particular 1 to 5% by weight, of aconitic acid.

It can also be advantageous to use mixtures of hydrogen carbonate compounds, citric acid and / or aconitic acid, the total amount of such a 50% by weight, preferably 40% by weight, advantageously 20% by weight, but in particular 10% by weight not being used should exceed, and should not fall below a minimum total amount of 0.1 wt .-%, preferably 1 wt .-%, each based on the entire suspension.

Surprisingly, it was found that in those cases in which carbon dioxide is released during drying, particles result which are characterized by an even further improved ability to absorb fragrances.

If the carrier material provided does not yet contain any nonionic surfactant after manufacture, the carrier material according to the invention is impregnated with at least one nonionic surfactant. If, on the other hand, the carrier material provided already contains nonionic surfactant during manufacture, the user is free to impregnate the carrier material according to the invention with at least one nonionic surfactant, depending on whether he wants to further increase the load of nonionic surfactant or not.

Subsequently, the carrier material containing the nonionic surfactant is loaded with perfume by mixing or spraying, as just described.

Another object of the invention is a detergent composition containing: o (A) particles according to the invention o (B) 0.01% by weight to 95% by weight, preferably 5% by weight to 85% by weight, preferably 3% by weight to 30% by weight, and more preferably 5% by weight. -% to 22% by weight of additional surfactant (s).

The detergent compositions can preferably be cleaning agents, (textile) care agents or detergents.

If the additional surfactant comprises anionic surfactant, preferably in a proportion of at least 50% by weight, based on the total amount of additional surfactant, it is a preferred embodiment, it being further preferred that the additional surfactant is a mixture of anionic and nonionic surfactants.

A detergent composition according to the invention which comprises at least one surfactant, preferably at least two from the group of alkylbenzenesulfonates, alkyl ester sulfonates, alkyl ethoxylates, alkylphenol alkoxylates, alkyl polyglucosides, alkyl sulfates, alkyl ethoxysulfate, secondary alkyl sulfates and / or mixtures thereof, these additional surfactants advantageously in amounts of 1% by weight % to 75% by weight, based on the total composition, is a preferred embodiment.

As described, the detergent composition contains, in addition to the surfactant contained in the particles according to the invention, additional surfactants. Advantageous surfactants are described below.

Anionic surfactants used are, for example, those of the sulfonate and sulfate type. Suitable surfactants of the sulfonate type are preferably C _8-13 alkyl benzene sulfonates, olefin sulfonates, ie mixtures of alkene and hydroxyalkane sulfonates, and the disulfonates obtained, for example, from C _12-16 monoolefins with terminal or internal double bond by sulfonation with Gaseous sulfur trioxide and subsequent alkaline or acidic hydrolysis of the sulfonation products. Alkanesulfonates which are derived from C ₁₂ are also suitable. ₁₈ -alkanes can be obtained, for example, by sulfochlorination or sulfoxidation with subsequent hydrolysis or neutralization. The esters of α-sulfofatty acids (ester sulfonates), for example the α-sulfonated methyl esters of hydrogenated coconut, palm kernel or tallow fatty acids, are also suitable. Other suitable anionic surfactants are sulfonated fatty acid glycerol esters. Fatty acid glycerin esters are to be understood as the mono-, di- and triesters and their mixtures as obtained in the production by esterification of a monoglycerin with 1 to 3 mol of fatty acid or in the transesterification of triglycerides with 0.3 to 2 mol of glycerol become. Preferred sulfated fatty acid glycerol esters are the sulfonation products of saturated fatty acids having 6 to 22 carbon atoms, for example caproic acid, caprylic acid, capric acid, myristic acid, lauric acid, palmitic acid, stearic acid or behenic acid. As alk (en) yl sulfates are the alkali and especially the sodium salts of the sulfuric acid half esters of C ₁₂ -C ₈ fatty alcohols, for example from coconut fatty alcohol, tallow fatty alcohol, lauryl, myristyl, cetyl or stearyl alcohol or the C ₀ -C ₂₀ oxo alcohols and those half-esters of secondary alcohols of this chain length are preferred. Also preferred are alk (en) yl sulfates of the chain length mentioned, which contain a synthetic, petrochemical-based straight-chain alkyl radical which have a degradation behavior similar to that of the adequate compounds based on oleochemical raw materials. The C ₂ -C ₁₆ alkyl sulfates and C ₁₂ - C ₁₅ alkyl sulfates and C ₁₄ -C ₁₅ alkyl sulfates are preferred for washing technology reasons. In addition, 2,3-alkyl sulfates, which are produced for example in accordance with US Patent No. 3,234,258 or 5,075,041 and can be obtained as commercial products from Shell Oil Company under the name DAN ^®, are suitable anionic surfactants.

Also, the Schwefelsäuremonoester with 1 to 6 moles of ethylene ethoxylated straight-chain or branched C _7-21 alcohols, such as 2-methyl-branched Cg-n-alcohols containing on average 3.5 mol ethylene oxide (EO) or Cι _2-18 fatty alcohols with 1 to 4 EO are suitable. Because of their high foaming behavior, they are used in cleaning agents only in relatively small amounts, for example in amounts of 1 to 5% by weight.

Other suitable anionic surfactants are also the salts of alkylsulfosuccinic acid, which are also referred to as sulfosuccinates or as sulfosuccinic acid esters and which are monoesters and / or diesters of sulfosuccinic acid with alcohols, preferably fatty alcohols and in particular ethoxylated fatty alcohols. Preferred sulfosuccinates contain C ₈ . ₁₈ fatty alcohol residues or mixtures thereof. Particularly preferred sulfosuccinates contain a fatty alcohol residue, which is derived from ethoxylated fatty alcohols, which in themselves are nonionic surfactants (description see below). Again, sulfosuccinates, the fatty alcohol residues of which are derived from ethoxylated fatty alcohols with a narrow homolog distribution, are particularly preferred. It is also possible to use alk (en) ylsuccinic acid with preferably 8 to 18 carbon atoms in the alk (en) yl chain or salts thereof.

Soaps are particularly suitable as further anionic surfactants. Saturated fatty acid soaps are suitable, such as the salts of lauric acid, myristic acid, palmitic acid, stearic acid, hydrogenated erucic acid and behenic acid, and in particular from natural fatty acids, e.g. Coconut, palm kernel or tallow fatty acids, derived soap mixtures.

The anionic surfactants, including the soaps, can be in the form of their sodium, potassium or ammonium salts and also as soluble salts of organic bases, such as mono-, di- or triethanolamine. The anionic surfactants are preferably in the form of their sodium or potassium salts, in particular in the form of the sodium salts.

The nonionic surfactants (additional surfactants) used are preferably alkoxylated, advantageously ethoxylated, in particular primary alcohols having preferably 8 to 18 carbon atoms and an average of 1 to 12 moles of ethylene oxide (EO) per mole of alcohol, in which the alcohol radical is linear or preferably in 2- The position may be methyl branched or may contain linear and methyl branched radicals in the mixture, as are usually present in oxo alcohol radicals. However, alcohol ethoxylates with linear residues of alcohols of native origin with 12 to 18 carbon atoms, for example from coconut, palm, tallow or oleyl alcohol, and an average of 2 to 8 EO per mole of alcohol are particularly preferred. The preferred ethoxylated alcohols include, for example, C ₁₂ . ₁₄ -alcohols with 3 EO or 4 EO, C ₉ - _ι alcohol with 7 EO, C ₁₃ - ₁₅ -alcohols with 3 EO, 5 EO, 7 EO or 8 EO, C ₁₂ . ₁₈ - alcohols with 3 EO, 5 EO or 7 EO and mixtures of these, such as mixtures of C ₁₂ . ₁₄ alcohol with 3 EO and C _12-18 alcohol with 5 EO. The degrees of ethoxylation given represent statistical averages, which can be an integer or a fraction for a specific product. Preferred alcohol ethoxylates have a narrow homolog distribution (narrow range ethoxylates, NRE). In addition to these nonionic surfactants, fatty alcohols with more than 12 EO can also be used. Examples include tallow fatty alcohol with 14 EO, 25 EO, 30 EO or 40 EO.

In addition, alkyl glycosides of the general formula RO (G) _x can also be used as further nonionic surfactants (additional surfactants), in which R is a primary straight-chain or methyl-branched, in particular in the 2-position methyl-branched aliphatic radical having 8 to 22, preferably 12 to 18 carbon atoms and G is the Is symbol which stands for a glycose unit with 5 or 6 carbon atoms, preferably for glucose. The degree of oligomerization x, which indicates the distribution of monoglycosides and oligoglycosides, is any number between 1 and 10; x is preferably 1.2 to 1.4.

Another class of preferably used nonionic surfactants (additional surfactants), which are used either as the sole nonionic surfactant or in combination with other nonionic surfactants, are alkoxylated, preferably ethoxylated or ethoxylated and propoxylated fatty acid alkyl esters, preferably with 1 to 4 carbon atoms in the alkyl chain, in particular Fatty acid methyl esters as described, for example, in Japanese patent application JP 58/217598 or which are preferably prepared by the process described in international patent application WO-A-90/13533.

Nonionic surfactants of the amine oxide type, for example N-coconut alkyl-N, N-dimethylamine oxide and N-tallow alkyl-N, N-dihydroxyethylamine oxide, and the fatty acid alkanolamides can also be suitable as additional surfactants. The amount of these nonionic surfactants is preferably not more than that of the ethoxylated fatty alcohols, in particular not more than half of them.

Further suitable additional surfactants are polyhydroxy fatty acid amides of the formula (II), R ² I R-CO-N- [Z] (II)

in which RCO stands for an aliphatic acyl radical with 6 to 22 carbon atoms, R ² for hydrogen, an alkyl or hydroxyalkyl radical with 1 to 4 carbon atoms and [Z] for a linear or branched polyhydroxyalkyl radical with 3 to 10 carbon atoms and 3 to 10 hydroxyl groups. The polyhydroxy fatty acid amides are known substances which can usually be obtained by reductive amination of a reducing sugar with ammonia, an alkylamine or an alkanolamine and subsequent acylation with a fatty acid, a fatty acid alkyl ester or a fatty acid chloride.

The group of polyhydroxy fatty acid amides also includes compounds of the formula (III) R ³ -OR ⁴ I R-CO-N- [Z] (III)

in which R represents a linear or branched alkyl or alkenyl radical having 7 to 12 carbon atoms, R ^{3 represents} a linear, branched or cyclic alkyl radical or an aryl radical having 2 to 8 carbon atoms and R ^{4 represents} a linear, branched or cyclic alkyl radical or an aryl group or an oxyalkyl group having 1 to 8 carbon atoms, which C-ι- ₄ alkyl or phenyl groups being preferred, and [Z] is a linear alkyl group of polyhydroxy whose alkyl chain is substituted with at least two hydroxyl groups, or alkoxylated , preferably ethoxylated or propoxylated derivatives of this residue.

[Z] is preferably obtained by reductive amination of a reduced sugar, for example glucose, fructose, maltose, lactose, galactose, mannose or xylose. The N-alkoxy- or N-aryloxy-substituted compounds can then, for example according to the teaching of international application WO-A-95/07331, be converted into the desired polyhydroxy fatty acid amides by reaction with fatty acid methyl esters in the presence of an alkoxide as catalyst.

The detergent compositions according to the invention, such as cleaning agents, care agents and detergents, can optionally also contain cationic surfactants. Suitable cationic surfactants are, for example, surface-active quaternary compounds, in particular with an ammonium, sulfonium, phosphonium, iodonium or arsonium group, as described, for example, by KH Wallhäußer in "Practice of Sterilization, Disinfection - Preservation: Germ Identification - Industrial Hygiene" (5th ed - Stuttgart; New York: Thieme, 1995) as antimicrobial agents. Through the use of quaternary surface-active compounds with an antimicrobial effect, the agent can be designed with an antimicrobial effect or its antimicrobial effect which may already be present due to other ingredients can be improved.

Particularly preferred cationic surfactants are the quaternary, partly antimicrobial ammonium compounds (QAV; INCI Quaternary Ammonium Compounds) according to the general formula (R ^I ) (R ^II ) (R ^III ) (R ^IV ) N ⁺ X ^~ , in which R ¹ to R ^lv identical or different C- ₂₂ alkyl radicals, C ₇ . ₂₈ aralkyl radicals or heterocyclic radicals, two or, in the case of an aromatic integration, as in pyridine, even three radicals together with the nitrogen atom, the heterocycle, for example a pyridinium or imidazolinium compound fertilize, form, represent and X ^{~ are} halide ions, sulfate ions, hydroxide ions or similar anions. For an optimal antimicrobial effect, at least one of the residues preferably has a chain length of 8 to 18, in particular 12 to 16, carbon atoms.

QAV are by reacting tertiary amines with alkylating agents such as Methyl chloride, benzyl chloride, dimethyl sulfate, dodecyl bromide, but also ethylene oxide can be produced. The alkylation of tertiary amines with a long alkyl radical and two methyl groups is particularly easy, and the quaternization of tertiary amines with two long radicals and one methyl group can also be carried out using methyl chloride under mild conditions. Amines which have three long alkyl radicals or hydroxy-substituted alkyl radicals are not very reactive and are preferably quaternized with dimethyl sulfate.

Suitable QAC are, for example, benzalkonium chloride (N-alkyl-N, N-dimethyl-benzylammonium chloride, CAS No. 8001-54-5), benzalkon B (m, p-dichlorobenzyldimethyl-C ₁₂ -alkylammonium chloride, CAS No 58390-78-6), benzoxonium chloride (benzyl-dodecyl-bis (2-hydroxyethyl) ammonium chloride), cetrimonium bromide (N-hexadecyl-N, N-trimethyl ~ ammonium bromide, CAS No. 57-09-0), benzetonium chloride (N, N-Dimethyl-N- [2- [2- [p- (1, 1, 3,3-tetramethylbutyl) phenoxy] ethoxy] ethyl] benzylammonium chloride, CAS No. 121-54-0), dialkyldimethylammonium chlorides such as Di-n-decyldimethylammonium chloride (CAS No. 7173-51-5-5), didecyldimethylammonium bromide (CAS No. 2390-68-3), dioctyldimethylammoniumchloric, 1-cetylpyridinium chloride (CAS No. 123-03 -5) and thiazoline iodide (CAS No. 15764-48-1) and their mixtures. Preferred QAV are the benzalkonium chlorides with C ₈ -C- | ₈ -alkyl radicals, in particular C ₁₂ -C ₁₄ -alkyl-benzyl-dimethylammonium chloride. A particularly preferred QAV cocospentaethoxymethylammonium methosulfate (INCI PEG-5 Cocomonium methosulfate; Rewoquat ^® CPEM).

To avoid possible incompatibilities of the antimicrobial cationic surfactants with anionic surfactants contained in the detergent composition according to the invention, anionic surfactant-compatible and / or as little cationic surfactant as possible are used or, in a particular embodiment of the invention, no cationic surfactants with an antimicrobial effect are used.

Instead, for example, parabens, benzoic acid and / or benzoate, lactic acid, salicylic acid and / or lactates can be used as antimicrobial substances. Benzoic acid and / or lactic acid are particularly preferred. The detergent compositions according to the invention, such as cleaning agents, care agents and detergents, can contain one or more cationic surfactants in amounts, based on the total composition, of 0 to 5% by weight, greater than 0 to 5% by weight, preferably 0.01 to Contain 3 wt .-%, in particular 0.1 to 1 wt .-%.

Likewise, the detergent compositions according to the invention, such as cleaning agents, care agents and detergents, can also contain amphoteric surfactants. Suitable amphoteric surfactants are, for example, betaines of the formula (R ¹ ) (R ² ) (R ³ ) N ⁺ CH ₂ CO ^~ , in which R ^{1 is} an alkyl radical with 8 to 25, preferably 10 to 21, carbon atoms and optionally interrupted by heteroatoms or heteroatom groups R ² and R ³ are identical or different alkyl radicals having 1 to 3 carbon atoms, in particular C ₁₀ -C ₂₂ - and C Alkyldimethylcarboxymethylbetain Cι _ι -Alkylamidopropyldimethylcarboxyme- thylbetain. The use of alkylamidoalkylamines, alkyl-substituted amino acids, acylated amino acids or biosurfactants as amphoteric surfactants in the agents according to the invention, such as cleaning agents, care agents and detergents, is also conceivable.

The detergent compositions according to the invention, such as cleaning agents, care agents and detergents, can contain one or more amphoteric surfactants in amounts, based on the overall composition, of 0 to 5% by weight, greater than 0 to 5% by weight, preferably 0.01 to Contain 3 wt .-%, in particular 0.1 to 1 wt .-%.

In addition to the wash-active substances, builders are the most important ingredients of detergents and cleaning agents, in particular zeolites, silicates, carbonates, organic cobuilders and - where there are no ecological prejudices against their use - phosphates. Accordingly, the detergent compositions can preferably also contain additional builders in addition to the builders present in the particles according to the invention. If the detergent composition thus further comprises at least 1% by weight of an additional detergent builder, there is a further preferred embodiment of the invention, it also being preferred if additional constituents customary for detergents and cleaning agents are also present.

Additional builders are, for example and in particular, the advantageous, preferably crystalline, layered sodium silicates or amorphous sodium silicates. Zeolite, preferably zeolite A and / or P, is also advantageous. Zeolite ^MAP® (commercial product from Crosfield) is particularly preferred as zeolite P. However, zeolite X and mixtures of A, X and / or P are also suitable. A co-crystallizate of zeolite X and zeolite A (approx. 80% by weight zeolite X), which is sold by CONDEA Augusta SpA under the brand name VEGOBOND AX ^® , is also available and can preferably be used in the context of the present invention and can be described by the formula nNa ₂ O ^• (1-n) K ₂ O ^• Al ₂ O ₃ ^• (2 - 2.5) SiO ₂ ^■ (3.5 - 5.5) H ₂ O. The zeolite can be used as a further builder, as well as for powdering the particles. Suitable zeolites preferably have an average particle size of less than 10 μm (volume distribution; measurement method: Coulter Counter) and preferably contain 18 to 22% by weight, in particular 20 to 22% by weight, of bound water.

Of course, the use of other customary additional builders is also advantageous, e.g. B. the generally known phosphates as builder substances in the detergent composition possible, provided that such use should not be avoided for ecological reasons. The sodium salts of orthophosphates, pyrophosphates and in particular tripolyphosphates are particularly suitable.

Usable organic builders are, for example, the polycarboxylic acids which can be used in the form of their sodium salts, such as citric acid, adipic acid, succinic acid, glutaric acid, tartaric acid, sugar acids, aminocarboxylic acids, nitrilotriacetic acid (NTA), provided that such use is not objectionable for ecological reasons, and mixtures of these. Preferred salts are the salts of polycarboxylic acids such as citric acid, adipic acid, succinic acid, glutaric acid, tartaric acid, sugar acids and mixtures of these.

In addition to the constituents already mentioned, other ingredients customary in washing and cleaning agents, in particular from the group of bleaching agents, bleach activators, enzymes, enzyme stabilizers, fluorescent agents, dyes, foam inhibitors, silicone oils, anti-redeposition agents, optical brighteners, graying inhibitors, color transmission inhibitors and corrosion inhibitors be introduced into or contained in the detergent composition. Other optional ingredients preferably come from the group of oligomeric and polymeric polycarboxylates, pH regulators, fluorescent agents, anti-shrink agents, wetting agents, antimicrobial agents, germicides, fungicides, antioxidants, antistatic agents, ironing aids, anti-repellants. and impregnating agents, swelling and anti-slip agents, chelating agents, fabric softeners and UV absorbers.

Among the compounds which serve as bleaching agents and supply H ₂ O ₂ in water, sodium perborate tetrahydrate and sodium perborate monohydrate are of particular importance. Further bleaching agents which can be used are, for example, sodium percarbonate, peroxypyrophosphates, citrate perhydrates and H ₂ O ₂ -producing peracidic salts or peracids, such as perbenzoates, peroxophthalates, diperazelaic acid, phthaloiminoperic acid or diperdodecedanoic acid.

In order to achieve an improved bleaching effect when washing at temperatures of 60 ° C. and below, bleach activators can be incorporated as the sole constituent or as an ingredient of component b). Bleach activators which can be used are compounds which, under perhydrolysis conditions, give aliphatic peroxocarboxylic acids having preferably 1 to 10 C atoms, in particular 2 to 4 C atoms, and / or optionally substituted perbenzoic acid. Substances which carry O- and / or N-acyl groups of the number of carbon atoms mentioned and / or optionally substituted benzoyl groups are suitable. Preferred are polyacylated alkylenediamines, in particular tetraacetylethylene diamine (TAED), acylated triazine derivatives, in particular 1,5-diacetyl-2,4-dioxohexahydro-1,3,5-triazine (DADHT), acylated glycolurils, in particular tetraacetylglycoluril (TAGU), N-acylimides, especially N-nonanoylsuccinimide (NOSI), acylated phenol sulfonates, especially n-nonanoyl- or isononanoyloxybenzenesulfonate (n- or iso-NOBS), carboxylic acid anhydrides, especially phthalic anhydride, acylated polyhydric alcohols, especially triacetate, especially triacetine, Diacetoxy-2,5-dihydrofuran.

In addition to the conventional bleach activators or in their place, so-called bleach catalysts can also be incorporated. These substances are bleach-enhancing transition metal salts or transition metal complexes such as, for example, Mn, Fe, Co, Ru or Mo salt complexes or carbonyl complexes. Mn, Fe, Co, Ru, Mo, Ti, V and Cu complexes with N-containing tripod ligands as well as Co, Fe, Cu and Ru amine complexes can also be used as bleaching catalysts.

Suitable enzymes are those from the class of proteases, lipases, amylases, celluloses or mixtures thereof. Bacterial strains are particularly suitable or fungi, such as Bacillus subtilis, Bacillus licheniformis and Streptomyces griseus, enzymatic active ingredients obtained. Proteases of the subtilisin type and in particular proteases which are obtained from Bacillus lentus are preferably used. Enzyme mixtures, for example of protease and amylase or protease and lipase or protease and cellulase or of cellulase and lipase or of protease, amylase and lipase or protease, lipase and cellulase, but in particular mixtures containing cellulase, are of particular interest. Peroxidases or oxidases have also proven to be suitable in some cases. The enzymes can be adsorbed on carriers and / or embedded in coating substances in order to protect them against premature decomposition. The proportion of enzymes, enzyme mixtures or enzyme granules in the compositions according to the invention can be, for example, about 0.1 to 5% by weight, preferably 0.1 to about 2% by weight.

In addition, the compositions can also contain components which have a positive influence on the oil and fat washability from textiles (so-called soil repellents). This effect is particularly evident when a textile is contaminated which has already been washed several times beforehand with a detergent according to the invention which contains this oil and fat-dissolving component. The preferred oil and fat-dissolving components include, for example, nonionic cellulose ethers such as methyl cellulose and methyl hydroxypropyl cellulose with a proportion of methoxyl groups of 15 to 30% by weight and of hydroxypropoxyl groups of 1 to 15% by weight, in each case based on the nonionic cellulose ether, and the polymers of phthalic acid and / or terephthalic acid or their derivatives known from the prior art, in particular polymers of ethylene terephthalates and / or polyethylene glycol terephthalates or anionically and / or nonionically modified derivatives thereof. Of these, the sulfonated derivatives of phthalic acid and terephthalic acid polymers are particularly preferred.

The compositions can contain, as optical brighteners, derivatives of diaminostilbenedisulfonic acid or its alkali metal salts. Suitable are, for example, salts of 4,4'-bis (2-anilino-4-morpholino-1, 3,5-triazinyl-6-amino) stilbene-2,2'-disulfonic acid or compounds of similar structure which instead of the morpholino- Group carry a diethanolamino group, a methylamino group, an anilino group or a 2-methoxyethylamino group. Brighteners of the substituted diphenyl styrene type may also be present, for example the alkali salts of 4,4'-bis (2-sulfostyryl) diphenyl, 4,4'-bis (4-chloro-3-sulfostyryl) diphenyl, or 4- (4-chlorostyryl) -4 '- (2-sulfostyryl). Mixtures of the aforementioned brighteners can also be used. In order to improve the aesthetic impression of the agents according to the invention, they can be colored with suitable dyes. Preferred dyes, the selection of which is not difficult for the person skilled in the art, have a high storage stability and insensitivity to the other ingredients of the compositions and to light, and no pronounced substantivity towards textile fibers, in order not to dye them.

If the detergent composition according to the invention is in the form of agglomerates and the density of the detergent composition is advantageously at least 300 g / l, advantageously 400 g / l, advantageously 500 g / l, preferably at least 600 g / l and in particular at least 650 g / l, it is also a preferred embodiment of the invention.

If the detergent composition according to the invention further comprises a second perfume which is sprayed onto the surface of the detergent granules contained, then again there is a preferred embodiment of the invention.

Another preferred embodiment is a detergent composition according to the invention in the form of a piece of laundry detergent, preferably in tablet form.

Another object of this invention is again a method for washing textiles, comprising the step of contacting the textiles with an aqueous medium which contains an effective amount of a detergent composition according to the invention which contains features as described above.

Another object of this invention is the use of nonionic surfactant to increase the perfume absorption capacity of the carrier material, and preferably to stabilize the perfume in the carrier material, and advantageously to produce a fragrance-retarding effect, as described at the beginning, and to achieve a fragrance-enhancing effect. Examples:

4 different particles were produced in a standard spray drying process.

Particle 1: consisted of

78% by weight of zeolite A (anhydrous active substance), 2% by weight of carboxymethyl cellulose sodium salt, 0.5% by weight of sodium hydroxide, 2% by weight of sodium sulfate, 1.45% by weight of C ₁₂ -C ₁₈ fatty alcohol with 4.5 EO, 0.5% by weight of C ₁₂ -C ₁₈ fatty alcohol with 7 EO and a residue (water, salts, impurities) of 15.55% by weight.

Particle 2: consisted of

78% by weight of zeolite A (anhydrous active substance), 2% by weight of carboxymethyl cellulose

Sodium salt, 0.5% by weight sodium hydroxide, 2% by weight sodium sulfate, 1.95% by weight C ₁₂ -C ₁₈

Fatty alcohol with 4.5 EO and a residue (water, salts, impurities) of 15.55

Wt .-%.

Particle 3: consisted of

78% by weight of zeolite A (anhydrous active substance), 2% by weight of carboxymethyl cellulose

Sodium salt, 0.5% by weight sodium hydroxide, 2% by weight sodium sulfate, 1.95% by weight C ₁₂ -C ₁₈

Fatty alcohol with 7 EO and a residue (water, salts, impurities) of 15.55

Wt .-%.

Particle 4 (comparison granulate): consisted of

79.95% by weight of zeolite A (anhydrous active substance), 2% by weight of carboxymethyl cellulose sodium salt, 0.5% by weight of sodium hydroxide, 2% by weight of sodium sulfate, and a remainder (water, salts, impurities) of 15.55% by weight.

These particles, the bulk densities of which were in each case approximately 600 g / l and which had a comparable particle size distribution, were subsequently subjected to perfume by mixing the perfume and the particles in a standard mixing unit. The following values were obtained for the perfume absorption by the respective granules.

Granules 1: amount of perfume absorbed: approx. 30% by weight Granules 2: amount of perfume absorbed: approx. 30% by weight granules 3: amount of perfume absorbed: approx. 30% by weight Granules 4: amount of perfume absorbed: approx. 20% by weight

The amount of perfume absorbed is based on the perfume-free particles. To do this, weigh the particles before and after the perfume application and measure the weight gain. The increase in weight represents the maximum possible perfume absorption of the respective particles. The particles remained free-flowing and did not stick together. If the amount of the perfume absorbed is given as 30% by weight, this means, to give an illustrative example, that 100 g of particles after the perfume application have a weight of 130 g.

It was therefore found that the particles which contained nonionic surfactant could absorb significantly more perfume than the granules which were free of nonionic surfactant. The increase was around 50%. Despite the high perfume load, the granules remained free-flowing and did not stick.
