    Abstract: 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.

    Abstract: The present invention relates especially to a composition for dyeing keratin fibres, in particular human keratin fibres such as the hair, comprising: (i) one or more fatty substances in a content ranging from 40% to 85% by weight relative to the total weight of the dye composition, (ii) one or more oxyethylenated fatty alcohols with an oxyethylene number of less than or equal to 10, and (iii) one or more nonionic surfactants of alkylpolyglucoside type, (iv) optionally one or more alkaline agents, (v) one or more direct dyes which are preferably cationic, anionic or neutral. The present invention also relates to a process for dyeing keratin fibres, comprising the application to the said fibres of an above mentioned composition, optionally in the presence of a composition comprising one or more chemical oxidizing agents; the dye composition possibly resulting from the mixing of several compositions. Finally, the invention relates to devices that are suitable for performing this process.

    Abstract: The present invention relates to a process for dyeing keratin fibres, in particular human keratin fibres such as the hair, comprising the successive application to said fibres (i) of a composition (A) containing at least one peroxygenated salt and (ii) of a substrate including a surface totally or partially coated with at least one layer containing one or more oxidation dyes; said process does not use any hydrogen peroxide during the application of the substrate to the fibres.
