One step hair coloring compositions using salts

A hair coloring composition comprising the following two compositions which are mixed just prior to application to the hair: (a) a composition comprising a water-soluble peroxygen oxidizing agent; and (b) a composition comprising one or more oxidative hair coloring agents selected from the group consisting of an aromatic diamine, an amino phenol, a naphthol, a polyhydric phenol, a catechol and mixtures thereof; wherein the composition comprising one or more oxidative hair coloring agents further comprises al least one water soluble carbonate releasing salts; and optionally a water soluble ammonium salt, is described.

Transition metal complexes as dye forming catalysts in hair coloring compositions

A hair coloring composition comprising a first composition which comprises: (a) a dye forming transition metal salt or complex; which is first applied to the hair; and a second composition which comprises the following two compositions which are mixed just prior to application to the hair: (a) a composition comprising a water-soluble peroxygen oxidizing agent; and (b) a composition comprising one or more oxidative hair coloring agents selected from the group consisting of an aromatic diamine, an aminophenol, a polyhydric phenol a catechol and mixtures thereof.

Enhanced color deposition for hair with sequestering agents

Process for dyeing keratinous fibers with 2,4-diamino-1,3-dimethoxybenzene at an acid ph and compositions employed

Process for dyeing keratinous fibres, especially human keratinous fibres such as the hair, characterised in that a composition containing, in a medium suitable for dyeing, at least 2,4-diamino-1,3-dimethoxybenzene as a coupler; an oxidation dye precursor; and an oxidising agent; is applied to these fibres, the pH of the composition applied to the fibres being less than 7.

Process for preparing 4-amino-3-methyl-N-substituted or unsubstituted alkylanilines

A process for the preparation of 4-amino-3-methyl-N-substituted or unsubstituted alkylanilines comprising acylating and/or sulfonylating 4-amino-3-methyl-nitro-benzene having the formula (I) STR1 with an acylation or sulfonylation agent to obtain a compound having the general formula (II) STR2 wherein R1 represents a hydrogen atom or an acyl group, R2 represents an acyl group or a sulfonyl group, or R1 and R2 can combine as a difunctional acyl group; reducing the nitro group of the compound having the general formula (II) with hydrogen in the presence of a metal hydrogenation catalyst to obtain a compound having the general formula (III) STR3 wherein R1 and R2 are as above defined; alkylating the amino group of the compound having the general formula (III) with an alkylation agent selected from the group consisting of an alkyl halide, a substituted alkyl halide and an alkylene oxide to obtain a compound having the general formula (IV) STR4 wherein R1 and R2 are as above defined, R3 represents an alkyl group or a substituted alkyl group and R4 represents a hydrogen atom, an alkyl group or a substituted alkyl group; and hydrolyzing the compound having the general formula (IV) to obtain a compound having the general formula (V) STR5 wherein R3 and R4 are as above defined.
