Description

Title of the invention: Composition comprising a particular oxidation coloring base, at least one particular coupler and at least one fatty substance.

[0001] The invention relates to a composition comprising at least one particular coloring base, at least one particular coupler and at least one fatty substance, the total fatty substance content being greater than or equal to 30% by weight, relative to the total weight of the composition.

[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.

[0007] However, the implementation of these dye compositions can present a certain number of drawbacks.

[0008] 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.

[0009] 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.

[0010] For example, 2-(methoxymethyl)benzene-1,4-diamine, as described in document CA2576189, and which is known to be an interesting coloring precursor, does not yet allow for entirely satisfactory dyeing properties, particularly in terms of selectivity. Indeed, it does not allow for a homogeneous coloring result to be obtained from root to tip. Furthermore, it does not allow for good coverage of keratin fibers, and in particular depigmented keratin fibers, such as white hair. Furthermore, its dyeing power is still too limited, thus leading to a restricted field of colorings.

[0011] 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 while having low selectivity and good tenacity and which is capable of leading to good dyeing performance, even after a period of storage.

[0012] 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), one of its addition salts, its solvates and / or the solvates of its salts: - at least one coupler chosen from: 6-hydroxy benzomorpholine of formula (II), its addition salts, its solvates and / or the solvates of its salts, hydroxyethyl-3,4-methylenedioxyaniline of formula (III), its addition salts, its solvates and / or the solvates of its salts, 2-amino 5-ethylphenol of formula (IV), its addition salts, its solvates and / or the solvates of its salts and mixtures thereof; - at least one fatty substance, the total fatty substance content being greater than or equal to 30% by weight, relative to the total weight of the composition.

[0013] According to a preferred embodiment, the composition according to the invention is a composition for coloring keratin fibers, in particular hair.

[0014] The composition according to the invention makes it possible in particular to produce powerful, intense and non-selective chromatic colorations, i.e. 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 good color build-up.

[0015] This composition also makes it possible to cover depigmented keratin fibers, such as white hair, particularly well.

[0016] 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.
