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 invention relates to a composition comprising the combination of at least one fatty substance, the total content of fatty substance being greater than or equal to 30% by weight, relative to the total weight of the composition, at least one particular carboxylic acid and at least one oxidation dye and/or an alkaline agent.

Composition comprising the combination of at least one fatty substance, a particular carboxylic acid and an oxidation dye and/or an alkaline agent

The present invention relates to a process for dyeing or bleaching keratin fibers, comprising the application to the keratin fibers of a composition comprising a high content of one or more particular amino acids followed by the application of a dyeing or bleaching composition.

Process for dyeing or bleaching keratin fibers using particular amino acids in high concentration

The present invention relates to a composition for treating keratin materials, in particular keratin fibres, and in particular human keratin fibres such as the hair, comprising, in a cosmetically acceptable medium: at least one fatty substance in a content of greater than or equal to 10% by weight relative to the total weight of the composition, at least one oxyalkylenated (OA), preferably oxyethylenated (OE), nonionic surfactant comprising a number of OA units, preferably OE units, ranging from 1 to 9, at least one oxyalkylenated (OA), preferably oxyethylenated (OE), nonionic surfactant comprising at least 10 OA units, preferably OE units, the weight ratio of the amount of oxyalkylenated (OA), preferably oxyethylenated, nonionic surfactant(s) comprising a number of OA units, preferably OE units, ranging from 1 to 9 to the amount of oxyalkylenated (OA), preferably oxyethylenated, nonionic surfactants comprising at least 10 OA units, preferably OE units, being greater than 1, at least one chemical oxidizing agent, preferably hydrogen peroxide. The composition in accordance with the invention may be used for dyeing, bleaching or permanently reshaping keratin materials, in particular keratin fibres. It produces ready-to-use compositions that give good dyeing, bleaching or permanent-reshaping properties without degrading the keratin materials, in particular keratin fibres, and without impairing their cosmetic properties.
