摘要:
The present invention relates to a process for the oxidation dyeing of keratin fibers implementing: a) a step of pretreating said fibers by application to said fibers of a cosmetic composition (B) comprising: i) at least one fatty substance in an amount of greater than or equal to 10% by weight relative to the total weight of the composition (B); and ii) at least one metal catalyst; b) optionally a washing, rinsing, drying and/or rubbing-dry step; c) followed by a step of dyeing by application to said fibers of a cosmetic composition (A) comprising: i) at least one oxidation base, preferably chosen from para-phenylenediamines, bis(phenyl)alkylenediamines, para-aminophenols, ortho-aminophenols, heterocyclic bases preferably comprising at least two nitrogen atoms, and addition salts thereof; ii) optionally at least one coupler; and iii) at least one chemical oxidizing agent. The dyeing process makes it possible to significantly improve the dyeing properties of the coloration, in particular in terms of selectivity, of chromaticity, and of color intensity and uptake. The use of a composition which is rich in fatty substances, i.e. greater than 10%, and contains at least one catalyst pretreatment, before oxidation dyeing, allows a clear improvement in the dyeing properties, in particular in terms of dye uptake onto keratin fibers, of strength and of chromaticity and of selectivity of the color.

The present invention relates to a process for dyeing human keratin fibres, in which use is made of one or more metal catalysts and a composition (A) comprising: (a) at least 10% by weight of one or more fatty substances, (b) one or more oxidation bases of formula (I) or (II), the addition salts thereof, solvates thereof and mixtures thereof: Formula (I), Formula (II) (c) one or more chemical oxidizing agents other than atmospheric oxygen. The invention also relates to a multi-compartment device and to a composition comprising all of the above-mentioned ingredients.

The invention relates to a process for dyeing keratin fibres by treating said fibres with i) at least one aromatic compound comprising a hydrocarbon-based polycycle comprising at least 10 carbon atoms, at least one of the rings of which is aromatic, ii) at least one indol(in)e compound; optionally iii) at least one metal salt, iv) at least hydrogen peroxide or at least one hydrogen peroxide-generating system and v) at least one basifying agent; to a dye composition comprising ingredients i) and ii), and optionally iii) to v) as defined previously and to a kit comprising ingredients i) to v) as defined previously. This hair dyeing process makes it possible to obtain better colorings which are more uniform, chromatic and long-lasting and which do not impair the cosmetic properties of the keratin fibres, and prevents changing of the colour associated with the presence of indol(in)e derivatives.
摘要:
The subject of the present invention is a process for the oxidation dyeing of keratin fibers, in particular human keratin fibers such as the hair, implementing: a) a step of treating said fibers by application to said fibers of a cosmetic composition (A) comprising: i) at least one fatty substance in an amount of greater than 10% by weight relative to the total weight of the composition (A), at least one metal catalyst; ii) at least one coupler; iii) optionally at least one oxidation base, preferably chosen from para-phenylenediamines, bis(phenyl)alkylenediamines, para-aminophenols, ortho-aminophenols, heterocyclic bases, addition salts thereof and solvates thereof; b) optionally a washing, rinsing, drying and/or rubbing-dry step; c) a step of treatment by application to said fibers of an oxidizing cosmetic composition (B) comprising at least one chemical oxidizing agent; and it being understood that steps a), b) and c) can be carried out successively a), then b), then c), or else a) then c), followed by b). The dyeing process makes it possible to significantly improve the dyeing properties of the coloration, in particular in terms of selectivity, of chromaticity, and of color intensity and uptake. The use of a composition which is rich in fatty substances, i.e. greater than 10%, and contains at least one catalyst, as a pretreatment, before oxidation dyeing, allows a clear improvement in the dyeing properties, in particular in terms of dye uptake onto keratin fibers, of strength and of chromaticity and of selectivity of the color.
