The present invention relates to a cosmetic composition in the form of an oil-in-water emulsion comprising: (i) at least one C-Cfatty alcohol; (ii) at least one anionic surfactant of general formula (I): RCOY(CH)nSOM; (iii) at least one oil; (iv) at least one wax, and (v) at least one hydrophilic solvent, the weight ratio of anionic surfactant(s) of general formula (I)/fatty alcohol(s) ranging from 1/5 to 1/3, said composition comprising from 1% to 10% by weight of wax(es) relative to the total weight of the composition. The present invention also relates to a process for preparing said composition and a cosmetic makeup and/or care process.

O/W emulsion comprising a C&#x2014;Cfatty alcohol, an anionic surfactant, an oil, a wax and a hydrophilic solvent

A subject-matter of the invention is a process for dyeing keratinous substances, in particular keratinous fibers, comprising the application, to the said keratinous fibers: of at least one composition A comprising at least one non-ionic alkylpolyglucoside surfactant, at least one metal salt and at least one thickening polymer and of at least one composition B comprising one or more ortho-diphenol derivative(s).

Dyeing process starting from ortho-diphenol

The invention relates to a process for dyeing keratin fibers by treating said fibers with i) at least one aromatic compound comprising a hydrocarbon-based polycycle comprising at least 10 carbon atoms, at least one of the rings of which is aromatic, ii) at least one indol(in)e compound; optionally iii) at least one metal salt, iv) at least hydrogen peroxide or at least one hydrogen peroxide-generating system and v) at least one basifying agent; to a dye composition comprising ingredients i) and ii), and optionally iii) to v) as defined previously and to a kit comprising ingredients i) to v) as defined previously. This hair dyeing process makes it possible to obtain better colorings which are more uniform, chromatic and long-lasting and which do not impair the cosmetic properties of the keratin fibers, and prevents changing of the color associated with the presence of indol(in)e derivatives.
