Abstract: Process for dyeing keratin fibres using a cosmetic composition comprising propane-1,3-diol and a dyeing composition The present invention relates to a process for dyeing keratin fibres, in particular human keratin fibres such as the hair, comprising the application to said fibres of an extemporaneous mixture of at least one cosmetic composition comprising propane-1,3-diol and at least one dyeing composition. The invention also relates to a multi-compartment device comprising at least one first compartment containing the cosmetic composition comprising propane-1,3-diol and at least one second compartment containing the dyeing composition.

Abstract: The invention relates to a composition comprising at least one oxidation dye, 1,3-propanediol, at least one alkaline agent and at least one fatty substance other than fatty acids.

Abstract: 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.

Abstract: 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.

Abstract: The present invention relates to a cosmetic composition for treating keratin fibres, in particular human keratin fibres such as the hair, comprising at least propane-1,3-diol in a content as defined hereinafter, at least one alkanolamine in a content as defined hereinafter, at least one fatty substance, and at least one oxidation dye. The present invention also relates to a process for dyeing keratin fibres, such as the hair, in which the composition as described previously, and comprising at least one dye, preferably chosen from oxidation dyes, 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.

Abstract: The present invention relates to a cosmetic composition for treating keratin fibres, notably human keratin fibres such as the hair, comprising N,N-dicarboxymethylglutamic acid, and/or salts thereof, solvates thereof and/or solvates of the salts thereof, 1,3-propanediol, at least one nonionic-surfactant chosen from (C6-C24 alkyl)polyglycosides, esters of C8-C30 fatty acids and of (poly)oxyalkylenated glycerol ethers, in particular of oxyethylenated and/or oxypropylenated glycerol ethers, and mixtures thereof, at least one alkaline agent and/or at least one dye. The present invention also relates to a process for dyeing and/or lightening keratin fibres, such as the hair, in which a composition comprising N,N-dicarboxymethylglutamic acid, and/or salts thereof, solvates thereof and/or solvates of the salts thereof, 1,3-propanediol, at least one nonionic surfactant, at least one alkaline agent and/or at least one dye is applied to said fibres.
