Description

The subject of the present invention is a composition comprising, in a cosmetically acceptable medium, at least one oxidation dye and at least one oxidation dye, and at least one oxidation dye and at least one oxidation dye. cationic polysaccharide It also relates to a method for staining human keratinous fibers, using such a composition, in the presence of a composition comprising at least one oxidizing agent. 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 dyeing involves one or more oxidation dye precursors, more particularly one or more oxidation bases optionally 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 makes it possible to obtain a rich palette of colors. The dyeing process comprises contacting the oxidation dye precursor (s) with an oxidizing agent, which is preferably hydrogen peroxide, under alkaline conditions. This contacting can be done in several ways. The first is to mix extemporaneously before use the coloring composition (that is to say the composition free of oxidizing agent) with an oxidizing composition comprising at least one oxidizing agent. The second is to apply successively, in one direction or the other, the coloring composition and the oxidizing composition, without intermediate rinsing. There are several difficulties with the compositions comprising oxidation dyes, particularly in terms of viscosity.

Thus, the viscosity of the coloring composition (that is to say the composition not comprising an oxidizing agent) must be sufficient to be able to be applied to the fibers, alone, before or after the oxidizing composition, being easily and not to cause drips outside the areas to be colored during the time necessary for the development of the color. The viscosity of the coloring composition must also be such as to allow easy mixing with an oxidizing composition, but also to give the ready-to-use composition thus obtained by mixing an appropriate viscosity so that it does not flow. more out of the areas to be colored during the time necessary for the development of the coloring. Obtaining a coloring composition satisfying these criteria is far from easy, especially if one does not want to impair the effectiveness of the coloring and obtain homogeneous, powerful, chromatic, and stubborn colors, for example.

One of the objectives of the present invention is therefore to provide oxidation dyeing compositions having an appropriate viscosity that retains good coloring efficiency.

These and other objects are achieved by the present invention which therefore relates to a composition, comprising in a cosmetically acceptable medium, one or more oxidation dyes and one or more cationic polysaccharides obtained from a polygalactomannan comprising mannose. in the main chain and galactose in the side chains, the mannose / galactose molar ratio being less than 1.5 and comprising one or more quaternary ammonium groups of formula (I) - (R40) n-CH2-CH (OH) - CH 2 -N + (R 1) (R 2) (R 3) X in which: R 2 and R 2, which are identical or different, represent a C 1 -C 3 alkyl group, R 3 represents a C 1 -C 24 alkyl group, X represents an anion n is an integer of 0 or 1 to 30, R4 represents a C1-C4 alkylene group.

It also relates to a process for staining human keratinous fibers, wherein this staining composition is used in the presence of a composition comprising one or more oxidizing agents.

Finally, it relates to a multi-compartment device comprising in at least one of them a coloring composition as defined above, and in at least one other, a composition comprising one or more oxidizing agents.

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.

The human keratinous fibers treated by the process according to the invention are preferably the hair.

A composition comprising at least one oxidation dye which is furthermore free of any oxidizing agent as defined below In the sense of the present invention, the term "dyeing composition" is intended to mean a composition that is ready for use, a composition staining as mentioned above to which was mixed extemporaneously before application, at least one composition comprising one or more oxidizing agents as defined below.

As indicated previously, the dyeing composition according to the invention comprises one or more cationic polysaccharides obtained from a polygalactomannan comprising mannose in the main chain and galactose in the side chains, the mannose / galactose molar ratio being less than 1 , And comprising one or more groups comprising a quaternary ammonium of formula (I) - (R40) n -CH2-CH (OH) -CH2-N + (R1) (R2) (R3) X - wherein: R1 and R2 identical or different, represent a C1-C3 alkyl group, R3 represents a C1-C24 alkyl group, X- represents an anion n is an integer equal to 0 or 1 to 30, R4 represents a C1-C4 alkylene group.

According to a particular embodiment of the invention, R 1 and R 2, which are identical or different, represent a methyl, ethyl or propyl group and even more preferentially a methyl group.

Preferably, R3 represents a C1-C4 alkyl group and in particular a methyl group.

Finally, R4 preferably represents an ethylene or methylene group and even more preferentially a methylene group.

Preferably, the group of formula (I) is carried by the galactose units.

More particularly, the molar ratio mannose / galactose is between 0.5 and 1.5 excluded, and even more advantageously, it is between 0.5 and 1.4, inclusive limits.

Preferably n is 1.

Polygalactomannans from which cationic polysaccharides are obtained can come from several plant sources. Thus, preferably with a mannose / galactose ratio of order 1/1, the polygalactomannan comes from the fenugreek gum from the fenugreek seed (Trigone / Fenum-Graecum).

The polysaccharides used in the context of the present invention may be obtained according to conventional methods known to those skilled in the art. In particular, the polygalactomannan can be modified by reacting some of the hydroxyl groups with a C2-C4 alkylene oxide. The product thus obtained is reacted with glycidyl-trialkylammonium or 3-halo-2-hydroxypropyltrialkyl ammonium salts. The reaction with the quaternary ammonium salt is advantageously carried out in a suitable solvent, such as an anhydrous alcoholic solvent, in the presence of an alkaline agent. A salt such as sodium chloride may be added to the reaction medium in order to prevent or limit the aggregation of the polysaccharide and / or to increase the yield of the reaction.

It should be noted that the polygalactomannan before being converted can be purified. As an example of a purification process, it is possible, for example, to dissolve the crude poylgalactomannane in water, to separate the dissolved polygalactomannan from the particles in suspension, to precipitate the filtrate in a suitable organic solvent and to dry the solid thus obtained.

According to one particular embodiment of the invention, the polysaccharide used moreover has a charge density of between 0.1 and 3 meq / g. Preferably, the cationic charge density is between 0.5 and 2.5 meq / g. It should be noted that the cationic charge density is generally measured according to the Kjeldahl method. It can also be calculated from the polymer structure.

Such polymers are described in particular in the international application WO 2005/073255 to which reference may therefore be made for more details on the definitions and characteristics of such polymers. Among the polymers that may be used, mention may be made, inter alia, of the products marketed under the US Pat. Catinal CF-100 designation by Toho Chemical Industry.

Usually, the content of cationic polysaccharides according to the invention represents from 0.01 to 10% by weight, more particularly from 0.1 to 5% by weight, and preferably from 0.2 to 2% by weight, relative to weight of the coloring composition.
