Description

Aqueous composition comprising at least one (bi)carbonate and / or (bi)carbonate-generating systems and at least one silicate in a particular ratio

[0001] The invention relates to an aqueous composition comprising at least one compound chosen from (bi)carbonates, (bi)carbonate-generating systems and their mixtures and at least one silicate in a particular ratio by weight.

[0002] The invention also relates to a process for dyeing and / or lightening keratin fibers, in particular the hair, employing this composition.

[0003] Finally, the invention relates to the use of such a composition for dyeing and / or lightening keratin fibers, and in particular the hair.

[0004] Many people have sought for a long time to modify the color of their hair and in particular to mask their gray hair.

[0005] It is known to dye keratin fibers, in particular human keratin fibers, such as the hair, in order to obtain “permanent” colorings, 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 pyrazolopyridines. These oxidation bases are colorless or weakly colored compounds which, in combination with oxidizing products, can give rise, by an oxidative coupling process, to colored compounds.

[0006] It is also possible to vary the shades obtained with these oxidation bases by combining them with couplers or coloring modifiers. The variety of the molecules employed as oxidation bases and couplers makes it possible to obtain a rich palette of colors.

[0007] However, the use of these dyeing compositions can exhibit a certain number of disadvantages.

[0008] This is because, after application to keratin fibers, the dyeing power obtained may not be entirely satisfactory, indeed even be weak, and result in a restricted range of colors. Moreover, they are not entirely satisfactory in terms of the cosmetic properties of the hair.

[0009] The colorings may also be insufficiently persistent with respect to external agents, such as light, shampoos or perspiration, and may also be too selective, that is to say that the difference in coloring is too great along one and the same keratin fiber which is differently sensitized between its end and its root.

[0010] Lightening compositions may not be efficient enough to achieve very light shades.

[0011] Moreover, dyeing and / or lightening compositions often comprise starting materials for which the regulatory conditions are increasingly strict. It is thus necessary to develop compositions comprising alternative compounds.

[0012] Consumers are moreover in search of dyeing and / or lightening products which are more environmentally friendly, in particular based on ingredients of natural origin, and which exhibit good working qualities, are easy to use and result in good dyeing and / or lightening properties.

[0013] The formulation of environmentally friendly cosmetic products, that is to say products whose design and development take account of environmental issues, is becoming a major preoccupation for contributing towards meeting the global challenges.

[0014] It thus proves to be essential to provide more sustainable compositions, thus making it possible to respond to these environmental challenges.

[0015] Thus, there exists a real need to make available a composition for dyeing and / or lightening keratin fibers, in particular human keratin fibers, such as the hair, which is more environmentally friendly and which does not exhibit the abovementioned disadvantages, that is to say which is capable of resulting in good build-up, intensity and chromaticity of the color when it comprises one or more dyes and / or good lightening performance qualities while having low selectivity and good persistence and which is capable of resulting in good dyeing performance qualities, or in good lightening performance qualities, making it possible in particular to obtain attractive blonds, even after a period of storage, while having good working qualities and resulting in good cosmetic properties, in particular in terms of uniformity of the smooth feel.

[0016] These aims and others are achieved by the present invention, which thus has as subject matter an aqueous composition comprising:- at least one compound chosen from (bi)carbonates, (bi)carbonate-generating systems and their mixtures;- at least one silicate;- water;- the total amount of (bi)carbonate(s) and / or (bi)carbonate-generating system(s) / total amount of silicate(s) ratio by weight is greater than 1.

[0017] Preferably, the composition according to the invention is a composition for the dyeing of keratin fibers, in particular the hair.

[0018] The composition according to the invention makes it possible in particular to result in chromatic, powerful and sparingly selective colorings, that is to say colorings which are uniform along the fiber. It also makes it possible to achieve various shades in a very wide palette of colors, of tinted and chromatic natural shades. In addition, it makes possible good build-up of the color.

[0019] This composition also makes it possible to cover particularly well depigmented keratin fibers, such as gray hair.

[0020] Moreover, the composition according to the invention exhibits good working qualities, in particular a creamy texture making possible quick and easy mixing with an oxidizing composition, if appropriate, and easy and uniform distribution over the entire head of hair. The composition according to the invention exhibits good stability over time, in particular little, indeed even no, change in its viscosity during storage. Moreover, the composition exhibits a texture which is uniform over time.

[0021] The composition according to the invention can also be a composition for the lightening of keratin fibers and in particular the hair.

[0022] The applicant company has found, surprisingly, that the composition according to the present invention made it possible to obtain effective lightening of keratin fibers with a more neutralized (less yellow) and more natural result.Moreover, the composition according to the invention is more respectful of the quality of the fibers, minimizing in particular their degradation.
