Description

The invention relates to oxidation dye preparations, the oxidation dye precursors and optionally direct dyes and dyeing auxiliaries contain medium in a carrier in the form of a flowable aqueous gel.

As a carrier for oxidation hair dye predominantly O / W creams or gels used. These preparations should after addition of the Oxida tion medium, usually an aqueous hydrogen peroxide preparation, a have creamy or viscous gel-like consistency, which is an application on the hair, z. B. with a brush, and allows some adhesion, without that the dye runs off the hair and wets the scalp or face.

Oxidizing dye preparations of the gel type are more common as the carrier wise solutions of soaps in mixtures of water and lower alcohols or glycols on. As soaps are usually the ammonium or alkanolammo used salts of oleic acid or oleic acid fatty acid fractions, since these are in mixtures of water and lower alcohols or glycols clear and when diluted with water or aqueous water form peroxide preparations viscous gels that are comfortable on the Apply to hair.

It has now been found that such oxidation dye preparations the base of oleic acid soaps as gelling surfactant in particular according to prolonged storage have an unpleasant odor, by the own Odor of the technical oleic acid qualities and the ent standing degradation products is conditional.

Surprisingly, it was found that structurally similar unsaturated Fatty acids of other chain length or configuration have a significantly lower content  geren smell and / or a higher stability against the chemical degradation respectively. In particular, it was found that the soaps of Petroselin acid (cis-6-octadecenoic acid) and / or elaidic acid (trans-g-octadecene acid) have a significantly more favorable performance behavior. Also, the soaps of gadoleic acid (cis-9-eicosenoic acid) and the brassidine Acid (trans-13-docosenoic acid) have a lower odor, a good storage stability and a favorable rheological behavior. The soaps of petroselinic acid and elaidic acid are preferred because They also show a more favorable rheological behavior, since they at the same concentration, a higher viscosity in both the dye gel as well as in the dyeing batch after admixture of the oxidizing agent be Act.

The invention therefore provides an oxidation dye preparation in Form of an aqueous, flowable gel containing oxidation dye products and, if appropriate, direct dyes and dyeing aids in an aqueous, soap-containing, gel-like carrier, characterized ge indicates that the soap is a water-soluble salt of an unsaturated salt Fatty acid from the group petroselinic acid, elaidic acid, gadoleic acid and Brassidic acid or mixtures thereof in an amount of 1 to 15% by weight is included.

Under a "flowable gel" here is a rheological state be understood, which is characterized by a high structural viscosity is, d. h. that these liquids under the influence of low shear forces, about its own weight, appear relatively high viscosity, but at An Use of higher shear forces, such as when mixed with aqueous oxidation medium preparations, let it move very easily. It is especially important in that after mixing with the aqueous hydrogen peroxide preparation the intrinsic viscosity of the dyeing batch is preserved and the use finished dyeing can be easily spread on the hair, not but runs off the hair and stains the scalp or face.

The characteristic fatty acids do not have to be chemically highly pure substances but can also be used in technical quality, i. It is possible to use technical fatty acid fractions containing these fats  acids as the main component in admixture with other fatty acids, eg. B. with Oleic acid, palmitoleic acid, erucic acid and minor amounts of saturated Contain fatty acids with 12 to 22 carbon atoms.

To convert the fatty acids into water-soluble soaps are Alka lihydroxide and alkali carbonates, ammonia, as well as mono-, di- and trialka nolamines having 2 to 4 C atoms in the alkanol group. Is preferably suitable the petroselinic acid in the form of ammonium, mono-, di- and triethanolammo niumseife.

The rheological state of the carrier as a flowable gel can be through the dosage of soap, water and the addition of a lower alcohol or Polyols control. By the addition of the lower alcohol or polyol is achieved that the gel even at higher soap levels flowable remains. The hair colorants according to the invention preferably contain 1 to 10 Wt .-% soap and 1 to 15 wt .-% of a lower alcohol or polyol.

Suitable lower alcohols are preferably ethanol and isopropanol. before zugt are also lower polyols having 2 to 6 carbon atoms, especially ethylene glycol, 1,2-propylene glycol, diethylene glycol, dipropylene glycol, glyce rin, erytheritol or trimethylolpropane.

As a further carrier component anionic, amphoteric, zwitterionic or nonionic surfactants, preferably in an amount of 0.5 to 5, ent be hold. Suitable z. B. linear alkyl sulfates having 12 to 18 carbon atoms in the alkyl group, Alkylpolyglycolethersulfate having 12 to 16 carbon atoms in the alkyl group and 1 to 6 glycol ether groups in the molecule, fatty alcohol polyglycol ethers obtained by addition of 6 to 20 moles of ethylene oxide to C10 C18 fatty alcohols are obtained, addition products of 6 to 20 mol Ethylene oxide with nonyl or dodecylphenol, fatty alkyl dimethylamine oxides, Fatty acid mono- or diethanolamides, N-fatty alkyl-dimethyl-glycine, N-fat alkylaminopropionic acid and other known surfactants, in particular ones having a good lime soap dispersibility.

The preparations according to the invention also contain dyes or dye precursors and dyeing aids. As dyes z. B.  direct hair dyes are used. As an oxidation dye precursors are suitable for. B. the known color bases or Entwicklerverbin applications and known modifiers or coupler compounds. The oxidation Dyes form by oxidative coupling of one or more Ent Wickler components with each other or with one or more Kupplerkompo in the presence of an oxidizing agent. As developer substances are usually primary aromatic amines with another, in Para or ortho position free or substituted hydroxy or amino group, diaminopyridine derivatives, heterocyclic hydrazone diis vate, 4-aminopyrazolone derivatives or tetraaminopyrimidines used. When so-called couplers are z. B. m-phenylenediamine derivatives, Phe nol, naphthols, resorcinol derivatives or pyrazolones.

Preference is given to oxidation dye precursors of the p-phenylenedi type amines, p-aminophenols or 2,4,5,6-tetraaminopyrimidines.

As Därbehilfsmittel z. B. leveling, stabilizing and / or the rheological behavior and foaming power improving additives ent hold.
