Description

Title of the invention: Composition comprising a particular oxidation coloring base and at least two particular couplers.

[0001] The invention relates to a composition comprising at least one particular oxidation coloring base and at least two particular couplers.

[0002] The invention also relates to a process for coloring keratin fibers, in particular hair, using this composition.

[0003] The invention finally relates to the use of such a composition for coloring keratin fibers, and in particular hair.

[0004] For a long time, many people have been looking to change the color of their hair, and in particular to hide their gray hair.

[0005] It is known to dye keratin fibers, in particular human keratin fibers such as hair, to obtain so-called permanent colorations with dye compositions containing oxidation dye precursors, in particular oxidation bases, such as ortho- or para-phenylenediamines, ortho- or para-aminophenols or heterocyclic compounds such as pyrazoles, pyrazolinones or pyrazolo-pyridines. These oxidation bases are colorless or weakly colored compounds which, combined with oxidizing products, can give rise to colored compounds by an oxidative condensation process.

[0006] It is also possible to vary the shades obtained with these oxidation bases by combining them with couplers or color modifiers. The variety of molecules used in the oxidation bases and couplers allows a rich palette of colors to be obtained. However, the implementation of these dye compositions can present a certain number of drawbacks.

[0007] Indeed, after application to keratin fibers, the tinctorial power obtained may not be entirely satisfactory, or even weak, and lead to a restricted range of colors.

[0008] The colorations may also not be sufficiently tenacious against external agents such as light, shampoos, perspiration and may also be too selective, that is to say that the difference in coloration is too great along the same keratin fiber which is differently sensitized between its tip and its root.

[0009] For example, 2-(methoxymethyl)benzene-1,4-diamine, as described in document CA2576189, which is known to be an interesting coloring precursor, does not yet make it possible to achieve entirely satisfactory dyeing properties, particularly in terms of selectivity. Indeed, it does not allow for a uniform color result from root to tip. Furthermore, it does not ensure good coverage of keratin fibers, and in particular depigmented keratin fibers, such as white hair. Furthermore, its tinctorial power is still too limited, thus leading to a restricted range of colorings.

[0010] Thus, there is a real need to provide a composition for coloring keratin fibers, in particular human keratin fibers such as hair, which does not have the drawbacks mentioned above, that is to say which is capable of leading to a good rise in color, to a powerful coloring, while having low selectivity and good tenacity and which is capable of leading to good dyeing performance, even after a period of storage.

[0011] These and other aims are achieved by the present invention which therefore relates to a composition comprising: - 2-(methoxymethyl)benzene-1,4-diamine of formula (I), its addition salts, its solvates and / or the solvates of its salts: NH, I i.

[0012]

[0013] XCH„ OJ NH. (I) - at least one coupler chosen from: 6-hydroxy benzomorpholine of formula (II), its addition salts, its solvates and / or the solvates of its salts and their mixtures; and o (II) - at least one coupler chosen from: 2-amino 5-ethylphenol of formula (III), its addition salts, its solvates and / or the solvates of its salts and their mixture OH (III). According to a preferred embodiment, the composition according to the invention is a composition for coloring keratin fibers, in particular hair. The composition according to the invention makes it possible in particular to produce chromatic, powerful, intense and non-selective colorations, that is to say colorations which are homogeneous along the fiber. It also makes it possible to achieve different shades in a very wide range of colors. In addition, it allows for good color buildup.

[0014] This composition also makes it possible to cover depigmented keratin fibers, such as white hair, particularly well.

[0015] The invention also relates to a kit comprising in a first compartment a composition as defined above and in a second compartment an oxidizing composition comprising at least one chemical oxidizing agent.
