Description

The subject of the present invention is a process for lightening and / or dyeing human keratinous fibers, using a method comprising a compound comprising a particular aminosilicone compound and a composition and a device. firstly a composition comprising a particular aminosilicon compound and secondly an oxidizing composition.

It also relates to a particular composition comprising a particular aminosilicon compound and at least one fatty substance. Finally, it relates to a multi-compartment device, at least one of which comprises the abovementioned composition and at least one other comprising an oxidizing composition.

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, more particularly one or more oxidation bases possibly associated with one or more couplers. Usually, oxidation bases are selected 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. The dyeing process comprises contacting the oxidation dye precursor (s) with an oxidizing agent, which is preferably hydrogen peroxide, under alkaline conditions. One of the difficulties lies in the fact that the most commonly used alkaline agent is ammonia, whose role is to adjust the pH of the composition to an alkaline pH to allow degradation of the oxidizing agent. Thus, the oxygen formed causes the condensation of the oxidation dye precursors as well as a lightening of the fiber due to the degradation of the melanin present. The basifying agent also has another role, that of swelling the keratin fiber to promote the penetration of the oxidant and dyes inside the fiber.

However, this alkalizing agent is very volatile, which causes inconvenience to the user because of the strong characteristic smell, rather annoying 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, this does not lead to compositions as effective as those based on ammonia, in particular because these alkalinizing agents do not provide sufficient lightening of the pigmented fibers in the presence of the oxidizing agent.

Another coloring mode used is that of the direct or semipermanent coloring. This method consists in applying to the keratin fibers direct dyes which are colored and coloring molecules, having an affinity for the fibers, to be left to allow the molecules to penetrate, by diffusion, inside the fiber, then to rinse them.

The direct dyes generally employed are chosen from nitrobenzene, anthraquinone, nitropyridine, azo, methine, azomethine, xanthene, acridine, azine or triarylmethane direct dyes. This staining mode does not require the use of an oxidizing agent unless it is desired to simultaneously obtain the coloring, a lightening of the fiber. In this case, the procedure is the same as for the oxidation dyeing, that is to say by bringing the keratinous fibers into contact with the dyeing composition in the presence of an oxidizing agent, more particularly hydrogen peroxide, in condition alkaline usually in the presence of ammonia. We are therefore also faced with the same difficulties as those detailed previously for oxidation dyeing.

In addition to the dyeing processes, it is also common to implement lightening processes in which the keratin fibers are brought into contact with an oxidizing composition under alkaline conditions. These methods consist solely in degrading the melanin of the hair, to a greater or lesser extent depending on the oxidizing agent chosen. Thus a peroxygenated salt generally leads to a more pronounced lightening than by employing hydrogen peroxide alone in alkaline conditions. However, whatever the oxidizing agent chosen, the lightening processes require the use of hydrogen peroxide under alkaline conditions and in particular in the presence of ammonia to form or accelerate the formation of oxygen. Therefore, there are again encountered the same difficulties as those of the dyeing processes carried out in the presence of an oxidizing agent and ammonia.

One of the objectives of the present invention is therefore to provide coloring and / or lightening compositions for human keratinous fibers intended to be used in the presence of an oxidizing agent which do not have the disadvantages that the existing compositions due to the presence of high levels of ammonia, while remaining at least as effective, both in terms of lightening and coloring, with in particular good performance in terms of chromaticity, power and homogeneity .

It should be noted that it was far from obvious to employ as alkalinizing agents, aminosilicon compounds corresponding to those of formula (I) in this type of process. In fact, in the presence of sufficient quantities of water, most of these compounds hydrolyze and condense rapidly. One could thus have expected a drop in the effectiveness of the coloration and / or the lightening because the silicon-based polymers resulting from this reaction penetrate little into the fiber because of their size, decreasing by the same amount. the lightening or coloring power of the composition.

These and other objects are achieved by the present invention which therefore relates to a process for staining and / or lightening human keratin fibers, wherein said fibers are brought into contact with: a first composition with a content of water of less than 10% by weight comprising one or more aminosilicon compounds of formula (I) 1 H2NuR4 Si R2 R3 (I) Formula in which: R1 denotes: - a linear or preferably branched C1-C20 alkoxy radical, preferably C4 - a hydroxyl radical - an OSi radical (Ra) 2 (Rb) R2 denotes: - a linear or branched C1-C4 alkyl radical, preferably methyl or ethyl - a linear C1-C20 alkoxy radical or branched, preferably C1-C4 - a hydroxyl radical - a radical OSi (Ra) 2 (Rb) Where: Ra denotes a linear or branched C1-C4 alkoxy radical, preferably ethoxy or methoxy, or a radical linear or branched C1-C4 alkyl, preferably methyl or ethyl 4 Rb desig a linear or branched C1-C4 alkyl radical, preferably methyl or ethyl
