Description

Composition comprising a particular coupler ammonium bicarbonate and fatty acid. The invention relates to a composition comprising at least one particular coupler ammonium bicarbonate and fatty acid. The invention also relates to a process for dyeing keratin fibres, notably the hair, using this composition. Finally, the invention relates to the use of such a composition for dyeing keratin fibres, and notably the hair. Many people have sought for a long time to modify the colour of their hair and in particular to mask their grey hair. In the field of dyeing hair keratin fibres, in particular human keratin fibres, it is already known practice to dye hair keratin fibres via various techniques using direct dyes or pigments for non-permanent dyeing, or dye precursors for permanent dyeing. There are essentially three types of process for dyeing the hair: a) “permanent” dyeing, the function of which is to afford a substantial modification to the natural colour and which uses oxidation dyes which penetrate into the hair fibre and form the dye via an oxidative condensation process; b) non-permanent, semi-permanent or direct dyeing, which does not use the oxidative condensation process and withstands four or five shampoo washes; it consists in dyeing keratin fibres with dye compositions containing direct dyes; c) temporary dyeing, which gives rise to a modification of the natural colour of the hair that remains from one shampoo wash to the next, and which serves to enhance or correct a shade that has already been obtained. It may also be likened to a “makeup” process. It is thus known practice to dye keratin fibres, in particular human keratin fibres such as the hair, to obtain “permanent” dyeing with dye compositions containing oxidation dye precursors, notably oxidation bases, such as ortho- or para-phenylenediamines, ortho- or para-aminophenols, or heterocyclic compounds such as pyrazoles, pyrazolinones or pyrazolopyridines. 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. 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 dye compositions may entail a certain number of drawbacks. Specifically, after application to keratin fibres, the dyeing power obtained may not be entirely satisfactory, or may even be weak, and lead to a limited range of colours. The colourings may also be insufficiently fast with respect to external agents such as light, shampoo washing 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. Consumers are moreover in search of dyeing products that are more environmentally friendly, notably based on ingredients of natural origin, and which have good application qualities, are easy to use and give good dyeing properties. The formulation of environmentally-friendly cosmetic products, i.e. products whose design and development take account of environmental issues, is becoming a major preoccupation for contributing towards meeting the global challenges. It thus proves essential to propose more sustainable compositions, thereby enabling these environmental challenges to be met. Thus, there is a real need to provide a composition for dyeing keratin fibres, in particular human keratin fibres such as the hair, which is more environmentally friendly and which is capable of producing good colour build-up, intensity and chromaticity, while at the same time having low selectivity and good fastness, notably good resistance to shampoo washing, and which is capable of delivering good dyeing performance, even after a period of storage, while at the same time having good application qualities and retaining good sensory performance notably in terms of sheen, smoothness, suppleness, straightening and disentangling of keratin fibres such as the hair. These aims and others are achieved by the present invention, one subject of which is thus a composition comprising: - at least one coupler chosen from: 6-hydroxybenzomorpholine of formula (I), the addition salts thereof, the solvates thereof and/or the solvates of the salts thereof, hydroxyethyl-3,4-methylenedioxyaniline of formula (II), the addition salts thereof, the solvates thereof and/or the solvates of the salts thereof, 2-amino-5-ethylphenol of formula (III), the addition salts thereof, the solvates thereof and/or the solvates of the salts thereof, and the mixtures thereof; (I) (II) (III) - ammonium bicarbonate- at least one fatty acid. According to a preferred embodiment, the composition according to the invention is a composition for dyeing keratin fibres, notably the hair. The comp
