Description

The invention relates to a composition comprising the combination of a particular oxidation dye precursor and a particular carboxylic acid. The invention also relates to a process for dyeing keratin fibres, in particular human keratin fibres such as hair, using this composition. Finally, the invention relates to the use of such a composition for dyeing keratin fibres, and in particular human keratin fibres such as hair. Many people have sought for a long time to modify the colour of their hair, and in particular to mask their grey hair. It is known practice to dye keratin fibres, in particular human keratin fibres such as the hair, to obtain permanent colourings with dyeing 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 colourless or weakly coloured compounds which, when combined with oxidizing products, can give rise to coloured compounds via a process of oxidative condensation. In this context the document IT201900005622A1 is considered to be relevant. It discloses coloring compositions comprising amongst others 2-amino-2-ethylphenol, hydroybenzomorpholine and hydroxyethyl-3,4-methylenedioxyaniline. It is also possible to vary the shades obtained with these oxidation bases by combining them with couplers or colour modifiers. The variety of molecules used as oxidation bases and couplers allows a wide range of colours to be obtained. However, the use of these dyeing compositions may have a certain number of drawbacks. Specifically, after application to the keratin fibres, the dyeing power obtained may not be entirely satisfactory, or may even be weak, and lead to a restricted range of colours. The colourings may also be insufficiently persistent with respect to external agents such as light, shampoo or perspiration, and may also be too selective, i.e. the difference in colouring is too great along the same keratin fibre that is differently sensitized between its end and its root. There is a real need to provide a composition for dyeing keratin fibres, in particular human keratin fibres such as the hair, which does not have the drawbacks mentioned above, i.e. which is capable of resulting in a colouring having an intense colour, with an improved fastness and also good coverage of the grey hair and good selectivity and which is capable of resulting in good dyeing performance levels, even after a period of storage. These aims and others are achieved by the present invention, one subject of which is thus a composition, in particular for dyeing keratin fibres, comprising: at least one oxidation coupler chosen from: i) 6-hydroxybenzomorpholine of formula (I), one of its addition salts, its solvates and/or the solvates of its salts, and mixtures thereof: ii) hydroxyethyl-3,4-methylenedioxyaniline of formula (II), one of its addition salts, its solvates and/or the solvates of its salts, and mixtures thereof: iii) 2-amino-5-ethylphenol of formula (III), one of its addition salts, its solvates and/or the solvates of its salts, and mixtures thereof: andat least one compound chosen from N,N-dicarboxymethyl glutamic acid, one of its salts, and mixtures thereof. Another subject of the present invention is a process for dyeing keratin fibres in which the composition according to the invention is applied to said fibres. According to a preferred embodiment, the composition according to the invention is a composition for dyeing keratin fibres, in particular the hair. The composition according to the invention may especially lead to chromatic, powerful, intense and sparingly selective colourings, i.e. to colourings that are uniform along the length of the fibre. It also allows various shades to be achieved in a very wide range of colours. Furthermore, it enables a good colour build-up. This composition also gives particularly good coverage of depigmented keratin fibres, such as grey hair. A subject of the invention is also 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. According to the invention, the term "chemical oxidizing agent" is intended to mean an oxidizing agent other than atmospheric oxygen. Other subjects, characteristics, aspects and advantages of the invention will become even more clearly apparent on reading the description and the examples which follow. In that which follows, and unless otherwise indicated, the limits of a range of values are included in this range, in particular in the expressions "of between" and "ranging from ... to ...". Moreover, the expression "at least one" used in the present description is equivalent to the expression "one or more". The composition according to the invention comprises at least one oxidation dye precursor. Oxidation couplers The com
