Description

The present invention relates to a composition for the dyeing of keratinous fibers, comprising (a) one or more oxidation bases, at least one of said bases of dyeing, The oxidation is 2- (methoxymethyl) benzene-1,4-diamine, (b) one or more liquid fatty substances, in a total amount greater than or equal to 30% by weight, relative to the total weight of the composition.

The invention also relates to a method for dyeing keratin fibers using this composition. The invention finally relates to the use of such a composition for dyeing keratinous fibers, and in particular the hair. For a long time, many people seek to change the color of their hair, and in particular to hide their white hair. It is known to dye keratinous fibers, in particular human keratinous fibers such as the hair to obtain so-called permanent dyes with dyeing compositions containing oxidation dye precursors, generally called oxidation bases such as orthoacids. or para-phenylenediamines, ortho- or para-aminophenols or heterocyclic compounds such as pyrazoles, pyrazolinones or pyrazolopyridines. 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 possible to vary the shades obtained with these oxidation bases by combining them with couplers or color modifiers. The variety of molecules involved in the oxidation bases and couplers allows a rich palette of colors to be obtained.

However, the implementation of these dye compositions may have a number of disadvantages. Indeed, after application to the keratinous fibers, the obtained dye power may not be entirely satisfactory, or even low, and lead to a restricted range of colors. The colorations may also not be sufficiently stubborn against external agents such as light, shampoos, perspiration and also be too selective, that is to say that the color difference is too important along the same keratin fiber which is differently sensitized between its tip and its root. By way of example, 2- (methoxymethyl) benzene-1,4-diamine, as described in document CA2576189, and which is known to be an interesting color precursor, does not yet make it possible to obtain entirely satisfactory dyes, especially in terms of selectivity. Indeed, it does not ensure good coverage of keratinous fibers, especially depigmented keratinous fibers, such as white hair. In addition, its dyeing power is often limited, thus leading to a limited color field. Thus, there is a real need to provide a coloring composition for keratinous fibers, in particular human keratin fibers such as the hair, which do not have the drawbacks mentioned above, that is to say which is capable of to lead to a wide range of colors while having low selectivity and good toughness. These and other objects are achieved by the present invention which therefore relates to a composition for dyeing keratin fibers, comprising: (a) one or more oxidation bases, at least one of said oxidation bases is chosen from 2- (methoxymethyl) benzene-1,4-diamine of formula (I), its addition salts or its solvates: o, CH3 N1-12 (I) (b) one or more fatty substances that are liquid at room temperature and at atmospheric pressure, different from the salified fatty acids, in a total amount greater than or equal to 30% by weight, relative to the total weight of the composition. The present invention also relates to a process for dyeing keratinous fibers in which the composition according to the invention is applied to said fibers.

The invention also relates to the use of said composition for dyeing keratinous fibers, and in particular the hair. The composition according to the invention makes it possible in particular to lead to chromatic colorings, which are powerful, intense and not very selective, that is to say to colorings which are homogeneous along the fiber. It also allows you to achieve different shades in a very wide range of colors. This composition also makes it possible to cover particularly well depigmented keratin fibers, such as white hair.
