The present invention relates to a composition for treating keratin fibres, notably human keratin fibres such as the hair, comprising at least one (C14-C30)alkyl (poly)glycoside, at least one fatty alcohol, at least one fatty acid, at least one alkaline agent and optionally at least one dye chosen from oxidation dyes, direct dyes and mixtures thereof. The present invention also relates to a process for dyeing and/or lightening keratin fibres, such as the hair, wherein the composition as described previously is applied to said fibres. The present invention also relates to the use of the composition according to the invention for dyeing and/or lightening, preferably dyeing, keratin fibres such as the hair.

Composition comprising at least one alkyl (poly)glycoside, at least one fatty alcohol, at least one fatty acid, and at least one alkaline agent

The present invention relates to a composition for treating keratin fibres, notably human keratin fibres such as the hair, comprising at least one nonionic surfactant, 1,3-propanediol, at least one fatty substance other than fatty acids in a content greater than or equal to 10% by weight relative to the total weight of the composition, and at least one dye. The present invention also relates to a process for dyeing keratin fibres, such as the hair, wherein the composition as described previously is applied to said fibres. The present invention also relates to a process for dyeing keratin fibres such as the hair, wherein the composition as described previously, and comprising at least one dye, preferably chosen from oxidation dyes, direct dyes and mixtures thereof, is applied to said fibres. The present invention also relates to the use of the composition according to the invention for dyeing keratin fibres such as the hair.

Composition comprising at least nonionic surfactant, 1,3-propanediol, at least one fatty substance, at least one colouring agent

The present invention relates to a composition for treating keratin fibres, notably human keratin fibres such as the hair, comprising at least one alkyl (poly)glycoside, N,N-dicarboxymethylglutamic acid, one of its salts, solvates and/or solvates of its salts, propane-1,3-diol, at least one fatty substance other than fatty acids, at least one dye. The present invention also relates to a process for dyeing keratin fibres, such as the hair, in which the composition as described previously is applied to said fibres. The present invention also relates to the use of the composition according to the invention for dyeing keratin fibres such as the hair.

Cosmetic composition comprising at least one alkyl (poly)glycoside, N,N-dicarboxymethylglutamic acid, propane-1,3-diol, at least one fatty substance other than fatty acids, at least one dye

The present invention therefore relates in particular to an aqueous cosmetic composition comprising one or more fatty substances in a content ranging from 40% to 80% by weight, relative to the total weight of the cosmetic composition, one or more oxyethylenated fatty alcohols having a number of oxyethylenes less than or equal to 10, one or more alkylpolyglucoside-type surfactants; the present invention also relates to using the cosmetic composition in an oxidative coloring or bleaching method for keratin fibers, particularly human keratin fibers such as hair.

Oil-rich aqueous composition and its use in an oxidative colouring or bleaching method

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.

Oxidation dyeing process implementing a pretreatment based on a composition rich in fatty substances and on metal catalysts
