Description

Title of the invention: Composition comprising a particular carboxylic acid or one of its salts, a (bi)carbonate in a particular content, an additional alkaline agent, a fatty substance and a colorant.

[0001] The invention relates to a composition comprising a particular carboxylic acid or one of its salts, at least one (bi)carbonate in a particular content, at least one additional alkaline agent, at least one fatty substance and at least one colorant.

[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] In the field of coloring hair keratin fibers, in particular human hair, it is already known to color hair keratin fibers by different techniques using direct dyes or pigments for non-permanent colorings or dye precursors for permanent colorings.

[0006] There are basically three types of hair coloring process: (a) so-called permanent coloring, the function of which is to bring about a significant change in the natural color and which uses oxidation dyes which penetrate the hair fiber and form the dye by a process of oxidative condensation; b) non-permanent, semi-permanent or direct coloring, which does not involve the oxidative condensation process and is resistant to 4 or 5 shampoos; consists of dyeing keratin fibers with dye compositions containing direct dyes; c) temporary coloring which results in a change in the natural color of the hair which lasts from one shampoo to the next and which serves to enhance or correct a shade already obtained. It can also be likened to a “makeup” process.

[0007] It is thus 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 bases Oxidation compounds are colorless or weakly colored compounds which, combined with oxidizing products, can give rise to colored compounds through a process of oxidative condensation.

[0008] 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.

[0009] However, the implementation of these dye compositions can present a certain number of drawbacks.

[0010] 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.

[0011] 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.

[0012] Consumers are also looking for more environmentally friendly coloring products, particularly those based on ingredients of natural origin, and which have good qualities of use, are easy to use and lead to good tinctorial properties.

[0013] The formulation of environmentally friendly cosmetic products, i.e. those whose design and development take environmental issues into account, is becoming a major concern in helping to meet global challenges.

[0014] It is therefore essential to offer more sustainable compositions that can respond to these environmental challenges.

[0015] Thus, there is a real need to provide a coloring composition for keratin fibers, in particular human keratin fibers such as hair, which is more environmentally friendly and which is capable of leading to good color buildup, intensity and chromaticity, while having low selectivity and good tenacity, in particular good persistence to shampooing, and which is capable of leading to good dyeing performance, even after a storage period, while having good usage qualities and retaining good sensory performance, in particular in terms of shine, softness, suppleness, smoothing, and disentangling of keratin fibers such as hair.

[0016] These and other aims are achieved by the present invention which therefore relates to a composition comprising: 1) at least one polycarboxylic acid of the following formula (I), its salts, their optical isomers, their geometric isomers, and / or their solvates:

[0017] RrN-(CH(R2)COOH)2 (I) in which Ri represents a hydrogen atom or a group -CH(COOH)-(CH2)2-COOH, -CH2CH2OH, -CH(CH3)COOH, -(CH2)2N(COR3)-CH2-COOH, or -CH(COOH)-CH2 -COOH; and Represents a CH2COOH group when Ri represents a hydrogen atom or R 2 represents a hydrogen atom when Ri is other than a hydrogen atom; and R3 represents a linear or branched alkyl group having from 1 to 4 carbon atoms or a cyclic group having from 3 to 30 carbon atoms; 2) at least one (bi)carbonate, the total (bi)carbonate content being greater than or equal to 1% by weight relative to the total weight of the composition; 3) at least one additional alkaline agent; 4) at least one fatty substance; and 5) at least one colorant.

[0018] According to a preferred embodiment, the composition according to the invention is a composition for coloring keratin fibers, in particular hair.

[0019] The composition according to the invention makes it possible in particular to produce powerful, intense and non-selective chromatic colorations, that is to say colorations which are homogeneous along the fiber.

[0020] The composition according to the invention has improved persistence to shampoos, as well as good stability over time, in particular little change, or even no change, in its viscosity during storage.

[0021] The composition according to the invention has good qualities of use, in particular in terms of texture, ease of application, adhesion to the hair, and lengthening.

[0022] The composition according to the invention also makes it possible to achieve good cosmeticity, particularly in terms of shine, softness, suppleness, a more natural feel, while preserving the integrity of the fiber.

[0023] The composition according to the invention also makes it possible to provide cosmetic compositions for keratin fibers which do not have a strong ammonia odor.

[0024] The invention also relates to a process for coloring hair using the composition of the invention.

[0025] 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.

Each of the mixtures is then applied to a lock of 90% white permed (BP) and moderately sensitized (SA20) hair at a rate of 5g of mixture / g of hair. After 35 minutes of application at 27°C, the hair is rinsed and washed with shampoo. standard and dried. Results

[0246] Colorimetric measurements were performed using a KONICA MINOLTA-3600 spectrocolorimeter (illuminant D65, angle 10°, specular component included) in the CIELab system.

[0247] Color selectivity is the variation in color between permanently colored (BP) and moderately sensitized (SA20) colored hair. Selectivity allows the homogeneity of color to be assessed throughout the hair fiber.

[0248] Selectivity is measured by:

[0249] AE, which is the color variation between permed hair and moderately sensitized hair (SA20), is obtained from the formula:

[0250] Where L* represents the intensity a* and b*, the chromaticity of permed colored hair and Lo* represents the intensity and a0* and b0* the chromaticity of moderately sensitized colored hair. The lower the value of AE, the lower the selectivity and the more uniform the coloring along the hair.

[0252] The locks of hair treated with the A+O mixture according to the invention have a much lower AE value than those treated with the comparative B+O mixture.

[0253] In other words, the A+O mixture according to the invention makes it possible to obtain locks of hair exhibiting better selectivity compared to those treated with the comparative B+O mixture.

[0254] Furthermore, the A+O mixture according to the invention makes it possible to obtain good sensory performances.
