according to the invention. A precursor of odoriferous substance is a compound that releases by breaking a chemical bond, for example by hydrolysis, an odor molecule and / or a molecule of desirable odoriferous substance. Typically, for the formation of an odoriferous substance precursor, a desired odoriferous raw material is chemically bonded with a vehicle, preferably a slightly volatile or moderately volatile vehicle. The combination leads to a precursor of less volatile and more hydrophobic odoriferous substance with better tissue deposition. The odoriferous substance is then released by breaking the bond between the odoriferous raw material and the vehicle, for example, due to a change in the pH value (for example, by perspiration during use), air humidity, heat and / or sunlight during storage or drying on the clothesline. The raw material of the odoriferous substance for use in odoriferous substance precursors are typically saturated or unsaturated volatile compounds, which contain an alcohol, an aldehyde and / or a ketone group. The raw materials of odoriferous substance useful in this case include any fragrant substance or mixture of substances.

5 to 30% by weight, preferably 7 to 20% by weight and in particular 9 to 15% by weight, respectively based on the washing or cleaning agent in total.

In another embodiment, the washing or cleaning agent does not contain any non-ionic surfactant or only small amounts, for example, <5% by weight, <2% by weight or <0.5% by weight.

As anionic surfactants, for example, those of the type of sulphonates and sulfates can be used. As surfactants of the sulphonate type, preference is given in this case to C9-13 alkyl benzenesulfonates, olefin sulfonates, that is, mixtures of alkene and hydroxyalkene sulfonates, as well as disulfonates, as obtained, for example, from C12-18 monoolefins with terminal

or internal double bond by sulfonation with gaseous sulfur trioxide and subsequent alkaline or acid hydrolysis of the sulfonation products. Also suitable are alkanesulfonates that are obtained from C12-18 alkanes, for example by sulphochlorination or sulfoxidation with subsequent hydrolysis or neutralization. Also suitable are esters of α-sulfograse acids (ester sulphonates), for example the α-sulphonated methyl esters of hydrogenated fatty acids of coconut, palm kernel or tallow. Other suitable anionic surfactants are glycerin esters of sulfonated fatty acids. With glycerin esters of fatty acids, mono-, di- and tri-esters, as well as mixtures thereof, are to be understood as obtained in the preparation by esterification of a monoglycerin with 1 to 3 mol fatty acid or in the transesterification of triglycerides with 0.3 to 2 moles of glycerin. Preferred sulfated fatty acid glycerin esters are in this case the sulfation products of saturated fatty acids with from 6 to 22 carbon atoms, for example caproic acid, caprylic acid, capric acid, myristic acid, acid lauric, palmitic acid, stearic acid

or behenic acid. As alk (en) yl sulfates, alkali and especially sodium salts of sulfuric acid half esters of C12-C18 fatty alcohols are preferred, for example coconut fatty alcohol, tallow fatty alcohol, lauryl alcohol, myristyl , cetyl or stearyl or of the C10-C20 oxoalcohols and those semi-esters of secondary alcohols of these chain lengths. Also preferred are alkylsulfates of said chain length, which contain a synthetic straight-chain petrochemical-based alkyl radical, which have a degradation behavior analogous to suitable compounds based on oleochemical raw materials. From the point of view of the technical interest of washing, C12-C16 alkyl sulfates and C12-C15 alkyl sulfates are preferred, as well as C14-C15 alkyl sulfates. Also suitable are anionic surfactants are 2,3-alkyl sulfates, which can be obtained as commercial products from Shell Oil Company under the name of DAN®. Also suitable are sulfuric acid monoesters of C7-21 alcohols of ethoxylated ethylene oxide with 1 to 6 moles of straight or branched chain, such as C9-11 2-methyl-branched alcohols containing an average of 3.5 moles of ethylene oxide (EO) or C12-18 fatty alcohols with 1 to 4 EO. In cleaning agents they are only used due to their high foaming, in relatively small amounts, for example in amounts of optionally 1 to 5% by weight. Other suitable anionic surfactants are also the salts of the alkylsulfonic succinic acid, also known as sulfosuccinates or sulfosuccinic esters and which represent monoesters and / or diesters of the sulfosuccinic acid with alcohols, preferably fatty alcohols and particularly ethoxylated fatty alcohols. Preferred sulfosuccinates contain C818 fatty alcohol radicals or mixtures thereof. Particularly preferred sulfosuccinates contain a fatty alcohol radical derived from ethoxylated fatty alcohols, which are non-ionic surfactants. In this case, sulfosuccinates whose fatty alcohol radicals are derived from ethoxylated fatty alcohols with a narrow homologous distribution are particularly preferred. It is also possible to use alkyl (en) yl succinic acid with preferably from 8 to 18 carbon atoms in the alkyl (en) yl chain or its salts. Soaps are preferred anionic surfactants. Saturated and unsaturated fatty acid soaps are suitable, such as salts of lauric acid, myristic acid, palmitic acid, stearic acid, erucic acid (hydrogenated) and behenic acid, as well as particularly soap mixtures from natural fatty acids, by example coconut, palm kernel, olive oil or tallow fatty acids. Anionic surfactants, including soaps may be presented in the form of their sodium, potassium or ammonium salts, as well as, as soluble salts of organic bases such as mono-, di- or triethanolamine. Preferably the anionic surfactants are in the form of their sodium or potassium salts, particularly in the form of sodium salts.

The possible content of preferred washing or cleaning agents of anionic surfactants is preferably> 0.1% by weight, for example from 2 to 30% by weight, preferably from 4 to 25% by weight and in particular from 5 to 22% by weight, referred respectively to the entire washing or cleaning agent. In a very particularly preferred embodiment of the invention, the entire washing or cleaning agent contains at least 5% by weight, preferably at least 8% by weight, particularly at least 10% by weight of surfactant. anionic

In addition to the anionic and / or non-ionic surfactants, the washing or cleaning agents may contain other ingredients that continue to improve the technical application and / or aesthetic properties of the washing or cleaning agent. In the context of the present invention, the preferred washing or cleaning agents may additionally comprise one or more substances, in particular from the group of odoriferous substances, bleaching agents, activators of bleaching agents, enzymes, fluorescent media, dyes, foam inhibitors, anti-redeposition agents, optics,

clarifiers, grating inhibitors, anti-shrinkage agents, anti-wrinkle agents, transfer inhibitors

color, antimicrobial agents, germicides, fungicides, antioxidants, other surfactants, such as hybrid ion or amphoteric surfactants, preservatives, corrosion inhibitors, antistatic agents, bitter agents, ironing agents, waterproofing and impregnating agents, swelling and anti-slip agents, neutral charge salts and UV absorbers.

As structural substances that may be present in the washing or cleaning agents, silicates, aluminum silicates (especially zeolites), carbonates, salts of di- and organic polycarboxylic acids, as well as mixtures of these substances, should be mentioned in particular. . The total amount of the optionally contained structural substances, comprising, for example, zeolite, polycarboxylate, sodium citrate, is preferably 1-70% by weight. Reasonable lower limits can be found, for example, at 5, 10, 15, 20 or 30% by weight, the% by weight referring to the entire agent. Reasonable upper limits can be found at 35, 40, 55 or 60% by weight.

Among the compounds used as bleaching agents, water supply H2O2, sodium perborate tetrahydrate and sodium perborate monohydrate are of particular importance. Other useful bleaching agents are, for example, sodium percarbonate, peroxypyrophosphates, citrate perhydrates, as well as peracid salts or H2O2 delivery peracids, such as perbenzoates, peroxophthalates, diperazelaic acid, phthalimino peracid or diperdodecane diacid. The total amount of optionally contained bleaching agent is preferably> 1% by weight, may be for example 5 to 25% by weight, or preferably also 10 to 20% by weight, based on% by weight of the entire agent , provided the presence of bleaching agent is desired.

In a very preferred and important embodiment of the invention, the washing or cleaning agent is characterized in that it is not any fabric softening agent or textile washing agent, in particular essentially it does not contain effective amounts of fabric softening components ( softening agents), such as esterquats. Not essentially containing effective amounts of fabric softener components means that the use of a typical product of the fabric softener components, which consists in producing a soft "touch" of the textile, cannot be achieved. The problem is that the active principle of softener components is that softener components, such as esterquats, adhere to textile fibers. The softening active ingredients can then attack in contact with the skin, eventually an already very sensitive skin and possibly negatively influence allergic problems in the upper layer of the skin in the already very sensitive skin. In addition, with the use of softening active substances, textile fibers can absorb less moisture, which in the case of certain textiles, such as towels, bathrobes, underwear, bedding, can eventually be negative. Therefore, the invention is particularly advantageous in this context as well, because the invention makes it possible now to achieve the particularly fresh smell of the clothing that is achieved with the use of fabric softener also without the use of fabric softener, only through the use of agents. washing or cleaning according to the invention. If desired, biocide quaternary ammonium salts with a hydrophobic radical, for example, dodecylbenzylammonium chloride, may, however, be contained in conventional amounts.

In a preferred embodiment of the invention, the washing or cleaning agent is presented in solid form, preferably in powder form, optionally also in compacted form. In relation to washing or cleaning agents, it is preferred that the microcapsules be contained in and / or on support particles.

A solid washing agent, particularly in powder form, preferred according to the invention, may contain in addition to the ingredients according to the invention (anionic and / or non-ionic surfactant, as well as encapsulated odoriferous substances and non-encapsulated odoriferous substances) preferably components which they are chosen for example from the following:
