摘要

Cosmetic composition in the form of an oil-in-water nanoemulsion for the oxidation dyeing of keratin fibres, and process for the same The present invention relates to a cosmetic composition(A) in the form of an oil-in-water nanoemulsion comprising one or more oxidation dyes, one or more surfactants, one or more fatty substances and water in a content of greater than or equal to 40% by weight relative to the total weight of the composition; the number-average size of the oil droplets in the said nanoemulsion being less than or equal to 100 nm. The present invention also relates to a process for dyeing keratin fibres, which consists in applying to the keratin fibres composition (A) according to the invention and in particular an oxidizing composition(B), the said composition possibly being in the form of a nanoemulsion.
