Description

 LIGHTING AND / OR COLORING OF HUMAN KERATINIC FIBERS USING A COMPOSITION COMPRISING A COMPOUND

The subject of the present invention is a process for lightening and / or dyeing human keratin fibers, using on the one hand a composition comprising one or more particular aminosilicon compounds and, on the other hand, an oxidizing composition. DESCRIPTION OF THE PREFERRED EMBODIMENTS

It also relates to a particular composition comprising one or more particular aminosilicon compounds and one or more fatty substances. 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 staining mode 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 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.

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 direct or semi-permanent 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 the latter case, the procedure is 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 alkaline condition 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 coloring processes implemented in the presence of an oxidizing agent and ammonia.

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

These and other objects are achieved by the present invention which therefore relates to a method for staining and / or lightening human keratin fibers, wherein said fibers are brought into contact with:

More particularly, the azo dyes comprise a function -N = N- whose two nitrogen atoms are not simultaneously engaged in a ring. However, it is not excluded that one of the two nitrogen atoms of the sequence -N = N- is engaged in a cycle. The dyes of the family of methines are more particularly compounds comprising at least one sequence chosen from> C = C <and -N = C <whose two atoms are not simultaneously engaged in a ring. It is however specified that one of the nitrogen or carbon atoms of the chains can be engaged in a cycle. More particularly, the dyes of this family are derived from methine, azomethine, mono- and di-arylmethane compounds, indoamines (or diphenylamines), indophenols, indoanilines, carbocyanines, azacabocyanines and their isomers, diazacarbocyanines and their isomers, tetraazacarbocyanines, hemicyanines.

These dyes may be monochromophoric dyes (that is to say comprising only one dye) or polychromophoric, preferably di- or tri-chromophoric dyes; the chromophores which may be identical or different, of the same chemical family or not. It should be noted that a polychromophoric dye comprises several radicals each derived from an absorbing molecule in the visible range between 400 and 800 nm. In addition, this absorbance of the dye does not require any prior oxidation thereof, or association with other (s) species (s) chemical (s).

In the case of polychromophoric dyes, the chromophores are connected to each other by means of at least one linker which may or may not be cationic. Preferably, the linker is a linear, branched or cyclic C 1 -C ₂₀ alkyl chain, optionally interrupted by at least one heteroatom (such as nitrogen, oxygen) and / or by at least one group comprising (CO, SO ₂ ), optionally interrupted by at least one heterocycle fused or not with a phenyl ring and comprising at least one quaternized nitrogen atom engaged in said ring and optionally at least one other heteroatom (such as oxygen, nitrogen or sulfur), optionally interrupted by at least one phenyl or substituted or unsubstituted naphthyl group, optionally at least one quaternary ammonium group substituted by two C 1 -C 6 alkyl groups; C15 optionally substituted; the linking arm does not comprise a nitro, nitroso or peroxo group.

It is first noted that the mixture according to the invention does not emit any aggressive odor unlike the mixture outside the invention.

The lightening is equivalent (difference not significant).

Example 3: Coloring
