Description

The present invention relates to a composition for the lightening and / or coloring of human keratinous fibers, which composition comprises compositions for the lightening and / or coloring of human keratinous fibers, and comprising a composition for lightening and / or coloring human keratin fibers comprising one or more fatty substances and one or more surfactants, ammonia and optionally one or more organic or inorganic bases, one or more oxidizing agents and water.

It also relates to a method for applying said composition. Finally, it relates to multi-compartment devices comprising a first compartment comprising an aqueous composition containing ammonia and at least a second compartment comprising an oxidizing composition containing one or more oxidizing agents.

The processes for lightening human keratin fibers generally consist in using an aqueous composition comprising at least one oxidizing agent, in an alkaline pH condition in the vast majority of cases. This oxidizing agent has the role of degrading the melanin of the hair and of oxidizing the possible precursors of oxidation dye present, 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. Among the methods for staining human keratin fibers, mention may be made of oxidation or permanent staining in lightening conditions. More particularly, this mode of staining uses one or more oxidation dye precursors, usually one or more oxidation bases optionally associated with one or more couplers, to vary the obtained shade, in the presence of an oxidizing agent. in alkaline conditions. The oxidation bases and the couplers are colorless or weakly colored compounds which, combined with oxidizing products, make it possible to access colored species by a process of oxidative condensation.

Also known direct or semi-permanent coloring in lightening conditions. This process consists in applying to the keratinous fibers, direct dyes which are colored and coloring molecules, having an affinity for the fibers, in the presence of an alkaline pH oxidizing agent, to be allowed to pausate to allow the molecules to penetrate, by diffusion, inside the fiber, and then rinsing them off. One of the difficulties of these methods, whether of discoloration or coloration, comes from the fact that they are carried out under alkaline conditions and that the most commonly used alkaline agent is ammonia. Ammonia is particularly advantageous in this type of process. Indeed, it allows one hand to adjust the pH of the composition to an alkaline pH to allow degradation of the oxidizing agent (thus its activation). This agent also causes a swelling of the keratinous fiber, with an opening of the scales, which promotes the penetration of the oxidant and, where appropriate, oxidation dyes, inside the fiber and therefore increases the effectiveness of the reaction.

However, this alkalizing agent is very volatile, which causes inconvenience to the user because of the strong characteristic odor, rather uncomfortable ammonia that emerges during the process. In addition, the amount of ammonia released requires the use of higher levels than necessary to compensate for this loss. This is not without consequences for the user who remains not only bothered by the smell but who may also be faced with greater risks of intolerance, such as irritation of the scalp (tingling). As for the option of purely and simply replacing all or part of the ammonia with one or more other conventional alkalizing agents, it does not lead to compositions as effective as those based on ammonia.

One of the objectives of the present invention is to provide lightening and / or lightening dyeing methods for human keratin fibers, the disadvantages of which are encountered with those using the existing compositions, are substantially reduced, while remaining at least as effective in terms of the lightening and homogeneity of the latter and also even more effective in terms of intensity, chromaticity and or homogeneity of the coloring obtained if dyes are present. It has indeed been found that the composition according to the invention makes it possible to trap at least part of the ammonia, with the consequence of appreciably reducing the inconvenience caused by the presence of this compound (in particular the odor) without impairing the effectiveness. of the composition.

These and other objects are achieved by the present invention which therefore relates to a composition for lightening and / or coloring human keratin fibers, characterized in that it comprises, in a cosmetically acceptable medium: at least 25% by weight of one or more fatty substances (b) an alkaline agent consisting of ammonia and optionally one or more organic or inorganic bases, the ratio of the molar amount of the ammonia present in the ammonia the total molar amount of organic or inorganic bases other than ammonia being greater than or equal to 0.65 (c) one or more surfactants (d) one or more oxidizing agents (e) of 30 to 70% water; (f) and optionally one or more dyes. It also relates to a method for staining human keratinous fibers comprising carrying out the aforementioned composition.

The invention likewise relates to a device with two compartments comprising 10 in one of them, a first aqueous composition containing one or more fatty substances, an alkaline agent consisting of ammonia and optionally one or more organic bases. or mineral, this first composition optionally comprising one or more dyes and optionally one or more surfactants, in the other, a second composition comprising one or more oxidizing agents; the compositions of the two compartments being intended to be mixed to give the composition according to the invention.

The invention finally relates to a device with three compartments comprising, in one of them, a first composition containing one or more fatty substances, one or more surfactants, in another, a second composition containing an alkaline agent consisting of ammonia and optionally one or more organic or inorganic bases, this second composition possibly comprising one or more dyes, and in the latter, a third composition containing one or more oxidizing agents; the compositions of the three compartments being intended to be mixed to give the composition according to the invention.
