PROCESS FOR LIGHTENING OR COLORING IN THE PRESENCE OF A PARTICULAR ANHYDROUS COMPOSITION AND DEVICE

The subject of the present invention is a process for lightening or staining human keratin fibers in the presence of an oxidizing agent, comprising the use of an anhydrous composition without surfactants comprising one or more oily fatty substances, an oxidizing composition, a composition comprising one or more alkaline agents and / or one or more dyes.

It also relates to a multi-compartment device of which a first compartment contains the aforementioned anhydrous cosmetic composition, a second, an oxidizing composition and a third a composition comprising one or more alkaline agents and / or one or more dyes.

Among the methods for staining human keratinous fibers, such as the hair, mention may be made of oxidation or permanent staining. More particularly, this mode of staining uses one or more oxidation dye precursors, usually one or more oxidation bases possibly associated with one or more couplers.

In general, the oxidation bases are chosen from ortho- or para-phenylenediamines, ortho- or para-aminophenols as well as heterocyclic compounds. These oxidation bases are colorless or weakly colored compounds which, combined with oxidizing products, make it possible to access colored species by a process of oxidative condensation.

Very often, the shades obtained with these oxidation bases are varied by combining them with one or more couplers, the latter being chosen in particular from aromatic meta-diamines, meta-aminophenols, meta-diphenols and certain heterocyclic compounds, such as indole compounds. The variety of molecules involved in the oxidation bases and couplers allows a rich palette of colors to be obtained. Also known direct or semi-permanent coloring. The method conventionally used in direct dyeing consists in applying to the keratin fibers direct dyes which are colored and coloring molecules, having an affinity for the fibers, to be allowed to pausate to allow the molecules to penetrate, by diffusion, into the interior of the body. the fiber, then rinse them. The direct dyes generally employed are chosen from nitrobenzene, anthraquinone, nitropyridine, azo, methine, azomethine, xanthene, acridine, azine or triarylmethane direct dyes. This type of process does not require the use of an oxidizing agent to develop the coloring. However, it is not excluded to implement in order to obtain with coloring, a lightening effect. This is called direct or semipermanent coloring in lightening conditions. The permanent or semi-permanent coloring processes under lightening conditions therefore consist in using, with the dye composition, an aqueous composition comprising at least one oxidizing agent, under alkaline pH conditions in the vast majority of cases. Among other things, this oxidizing agent has the function of degrading the melanin of the hair, which, depending on the nature of the oxidizing agent present, leads to a more or less pronounced lightening of the fibers. Thus, for relatively low lightening, the oxidizing agent is generally hydrogen peroxide. When greater lightening is desired, it is customary to use peroxygenated salts, such as persulfates for example, in the presence of hydrogen peroxide. There is a need to have a satisfactory effectiveness of the lightening and coloring products while reducing the adverse effects associated with the simultaneous presence of alkaline agents and oxidizing agents such as hydrogen peroxide. These adverse effects are mainly at the level of the degradation of keratinous fibers and at the level of the odors of the alkaline agents used such as ammonia and amines. It is therefore sought to increase the effects of alkaline agents and / or oxidizing agents to limit their concentrations.

French patent applications FR2925307 and FR2925311 have thus been proposed for lightening processes using three compositions including an anhydrous combination of fatty substances and surfactants. The industrial production, the homogeneity and the stability of the anhydrous compositions described therein are to be improved while preserving, or even improving, the dyeing results obtained after using the lightening or coloring processes using these anhydrous compositions. especially in terms of power and selectivity.

One of the objectives of the present invention is to provide a lightening or coloring process which solves these problems.

It also relates to a multi-compartment device comprising in a first compartment, an anhydrous cosmetic composition (A) free of surfactants, and comprising one or more liquid fats at 25 ° C and at atmospheric pressure, in a second composition (B). ) comprising at least one oxidizing agent, and in a third, a composition (C) comprising one or more alkaline agents and / or one or more oxidation dyes, one or more direct dyes, or mixtures thereof; the sum of the amounts of liquid fatty substances present in the compositions (A), and optionally (B) and / or (C), representing at least 25% of the total weight of the ready-to-use composition resulting from the mixing of the compositions ( A), (B) and (C).
