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 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.
