Description

Composition comprising (2,5-diaminophenyl) ethanol, an anionic carboxylic polymer in a medium rich in fatty substances, dyeing method and device The present invention relates to a dyeing composition for keratinous fibers, in particular fibers human keratin, such as the hair, comprising a) one or more fatty substances, preferably liquid non-silicone, b) one or more carboxylic, and preferably acrylic, anionic polymers, c) (2,5-diaminophenyl) ethanol and its acid salts or its solvates, d) optionally one or more couplers, e) optionally one or more alkalinizing agents, f) one or more chemical oxidizing agents such as hydrogen peroxide, and whose fat content represents at least total at least 10% by weight, preferably at least 25% by weight relative to the total weight of the composition. The invention also relates to a dyeing process using said composition and a device with several compartments, suitable for the implementation of said dye composition. The present invention relates to the field of dyeing keratin fibers and more particularly to that of hair dyeing. For a long time, many people have been trying to change the color of their hair and in particular to hide their white hair. One of the staining modes is so-called permanent staining or oxidation which uses dye compositions containing oxidation dye precursors, generally called oxidation bases. These oxidation bases are colorless or weakly colored compounds which, when combined with oxidizing products, can give rise to colored compounds by a process of oxidative condensation.

It is also known that the shades obtained with these oxidation bases can be varied by combining them with couplers or color modifiers, the latter being chosen in particular from aromatic meta-diamines, meta-aminophenols, meta-aminophenols and meta-aminophenols. 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. It is also possible to use direct dyes to bring particular reflections to the coloring obtained. These direct dyes are colored molecules and dyes, having an affinity for the fibers. For example, mention may be made of nitrobenzene, anthraquinone, nitropyridine, azo, xanthene, acridine, azine or triarylmethane direct dyes.

The permanent coloring processes thus consist in using with the dyeing composition, an aqueous composition comprising at least one oxidizing agent, under alkaline pH conditions in the vast majority of cases. This oxidizing agent has the role, at least in part, 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. The oxidizing agent employed is usually hydrogen peroxide. One of the difficulties encountered in carrying out the prior art dyeing processes is that they are carried out under alkaline conditions and that the most commonly used alkalizing agents are ammonia and ammonia. amines. Indeed, the basifying agent makes it possible to adjust the pH of the composition to an alkaline pH to allow the activation of the oxidizing agent. In addition, this basifying agent causes swelling of the keratinous fiber, with uprising of the scales, which promotes the penetration of the oxidant, as well as dyes if they are present, essentially the oxidation dyes, inside. fiber, and thus increases the efficiency of the coloring or lightening reaction.

However, these alkalinizing agents, especially ammonia, have the disadvantage of causing inconvenience to the user because of their strong characteristic odor. In particular, the user may be not only inconvenienced by the odor given off by these alkalinizing agents but may also be faced with greater risks of intolerance, such as, for example, irritation of the scalp resulting in particular by tingling. It is also important to obtain colorations that are satisfactorily resistant to light. But the use of certain couplers such as meta-phenylene diamines for example induces degradation by solar radiation. Furthermore, it has been proposed in the oxidation dyeing the use of a (2,5-diaminophenyl) ethanol-type oxidation base (EP 0 858 796). Staining is also known which uses this oxidation base, in particular associated with particular acids such as diethylenetriamine-penta (methylene) phosphonic acid, (EP 2 103 299) or with chlorinated bases or chlorinated couplers such as ( 2-amino-6-chloro-4-nitrophenol, 2,6-dichloro-4-aminophenol, 2-chloro-6-ethylamino-4-nitrophenol 3-amino-5-chloroaniline, 2-chloro-2-chloroaniline 4-aminophenol or 2-chloro-6-methyl-3-aminophenol (WO 98/17233, WO 98/19658, WO 98/19659, WO 98/19660, EP 0 985 406, EP 0 727 203, DE 19828204, DE 19724334 or WO 96/15765), or couplers such as 3- (2,4-diaminophenoxy) -1-propanol (WO 2001/051019). However, these combinations of bases, couplers and acids produce colors that are not always satisfactory, having limited or even insufficient dyeing power to ensure, for example, a suitable coverage of the white hairs and / or excessive selectivity of the coloration between the root and the tip. and / or insufficient toughness vis-à-vis external aggressions such as light, shampoos, weather, etc. In addition, none of these documents describes a dye composition comprising a large amount of fatty substances, in particular oil.

One of the objectives of the present invention is therefore to provide compositions for staining human keratinous fibers such as the hair, which do not have the drawbacks of existing compositions.

In particular, the composition according to the invention in the presence of a chemical oxidant makes it possible to obtain satisfactory colors, particularly in terms of power in general but also with sufficient cover or rise of the color at the root of the hair, which avoids a "root" effect of the coloring.

The colorations obtained are also not very selective. Finally, it is also possible to obtain very stable colorings with respect to light. In addition, the invention makes it possible to achieve significant degrees of lightening while coloring, without using persalts or to force the amount of chemical oxidizing agent or alkalizing agent. These and other objects are achieved by the present invention which therefore relates to a cosmetic composition, for dyeing keratinous fibers, in particular human keratinous fibers such as the hair, comprising: a) one or more fatty substances, preferably non-silicone liquids; b) one or more carboxylic anionic polymers, c) one or more oxidation bases selected from (2,5-diaminophenyl) ethanol and also its acid salts or solvates such as hydrates; d) optionally one or more coupler (s); e) optionally one or more basifying agent (s); f) one or more chemical oxidizing agent (s) such as hydrogen peroxide; and the fat content totaling at least 10% by weight relative to the total weight of the composition, more particularly at least 25% by weight, relative to the total weight of the composition.

The subject of the present invention is also a process for dyeing keratinous fibers, in particular human keratinous fibers such as the hair, in which the dyeing composition according to the invention is applied to said fibers.

The invention also relates to a multi-compartment device for implementing the composition according to the invention. Thus, the use of the dyeing composition according to the invention leads to powerful, intense, chromatic and / or slightly selective coloring, that is to say dyes that are homogeneous along the fiber. The dyeing process of the invention also makes it possible to cover the keratinous fibers at their roots particularly particularly up to three centimeters from the base of said fibers. In addition, the colors obtained after treatment of the fibers remain stable, particularly with respect to light. The invention also makes it possible to reduce the amounts of active agents of the invention such as dyes and / or alkanilizing agents and / or oxidizing agents.

Furthermore, the process according to the invention makes it possible to use less smelly compositions when they are applied to the hair or during their preparation. Other characteristics and advantages of the invention will emerge more clearly on reading the description and examples which follow. In what follows, and unless otherwise indicated, the boundaries of a domain of values are included in this field.
