The invention concerns ready to use compositions for the reshaping and direct coloring of hair comprising glyoxylic acid, a glyoxyloyl amino acid or a mixture thereof and a direct dye, and a method for reshaping and coloring of hair by means of said compositions.

Compositions and methods for simultaneous reshaping and direct coloring of hair

The present invention relates to oxidative hair colorants containing a buffer system consisting of saccharine and at least one alkanolamine. The colorants are free of ammonium hydroxide and sources of ammonia.

Cationic naphthyldiazo dyes of general formula (I) and colorants for keratin fibers containing these dyes.

Cationic naphthyldiazo dyes and keratin fibers-coloring agents containing these dyes

Novel cationic 4,5-diaminopyrazole derivatives of general formula (I) the colorants for keratin fibers containing these compounds and a process for producing the compounds of formula (I).

Cationic diaminopyrazoles, a process for producing them and colorants containing these compounds

The object of the present invention are (3,5-diaminophenyl)(2,4-dihydroxyphenyl)methanone and the acid adducts thereof of formula (I), with 0&#x2266;n&#x2267;2 and HX denoting an inor-ganic or organic acid, the colorant containing these compounds and a method for producing the compounds of formula (I).

(3,5-diaminophenyl)(2,4-dihydroxyphenyl)methanone and the acid adducts thereof, method for their preparation and use of these compounds for dyeing fibers

The present invention relates to novel m-diaminobenzenes of formula (I) to the use thereof in colorants and to the oxidative hair colorants containing said m-diaminobenzenes.

M-diaminobenzenes, their acid adducts and the use thereof in colorants

The cosmetic composition for cosmetically treating parts of the body comprising keratin-containing material includes one or more conventional cosmetic auxiliary ingredients and a cosmetically active compound, which is prepared by covalently bonding peptide linker molecules with known organic cosmetic effector molecules. The peptidic linker group is a peptide group, preferably with from 2 to 15 amino acids, which has binding specificity for keratin-containing material. The organic cosmetic effector molecules have dyeing, care-imparting, conditioning, protective, hardening, softening, repairing and/or strengthening properties for keratin-containing material. The method of cosmetically treating parts of the body that include keratin-containing material, for example a method of dyeing hair, includes applying the above-described cosmetic composition to the parts of the body.

Highly affine cosmetic agent

The composition for dyeing fibers is obtained before use by mixing a first component A1, containing at least one enamine of the formula (I) with a second component A2, containing at least one carbonyl compound. A multi-component kit for dyeing and, later on, decolorizing fibers, and a method for temporarily dyeing hair with the composition for dyeing fibers and later removing the dyed hair color with a decolorizing component B containing a sulfite are also provided. The multi-component kit for dyeing and, later on, decolorizing fibers, separately contains the first component A1, the second component A2 and the decolorizing component B.

Multi-component kit and method for temporarily dyeing and later decolorizing hair

N-Aryl-4,5-diaminopyrazole of formula (I) or a physiologically compatible salt thereof of an organic or inorganic acid wherein

N-aryl-4,5-diaminopyrazoles and dyes containing said compounds

Bridged diaminopyrazole compounds and dye compositions containing same

The aqueous or aqueous-alcoholic oxidative dye precursor composition includes 1,4-diamino-2-methoxymethylbenzene, or a physiologically compatible salt thereof, as developer substance and one or more conventional coupler compounds. A ready-to-apply hair dyeing mixture having a pH of 6 to 10.5 is made by mixing the aqueous or aqueous-alcoholic oxidative dye precursor composition with an oxidizing agent, such as 6% hydrogen peroxide in a weight ratio of 5:1 to 1:3. The compositions may also contain conventional cosmetic additive ingredients and direct-dyeing dye compounds.

Compositions containing 1,4-diamino-2-methoxymethylbenzene and salts thereof and methods for dyeing keratin fibers with same

The method of dyeing keratin fibers includes the steps of providing an oxidation dye precursor composition containing from 0.01 to 10 percent by weight of a total amount of at least one coupler compound and at least one developer compound, mixing the oxidation dye precursor composition with an oxidizing agent and applying the resulting mixture to the keratin fibers. The oxidation dye precursor composition is characterized by containing 1,4-diamino-2-methoxymethylbenzene, or a physiologically compatible salt thereof, either alone as sole developer compound, or in combination with other known developer compounds. The oxidation dye precursor composition can also contain at least one direct-dyeing dye compound and conventional cosmetic additive ingredients.
