Description

Title of the invention: Composition comprising hyaluronic acid and / or one of its derivatives, a (bi)carbonate, a fatty acid and a colorant.

[0001] The invention relates to a composition comprising hyaluronic acid and / or one of its derivatives, at least one (bi)carbonate, at least one fatty acid 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 using 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:

[0007] a) so-called permanent coloring which has the function of bringing about a significant modification of the natural color and which uses oxidation dyes which penetrate into the hair fiber and form the dye by a process of oxidative condensation;

[0008] 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 dyeing compositions containing direct dyes;

[0009] 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 “make-up” process.

[0010] 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 oxidation bases are colorless or weakly colored compounds which, combined with oxidizing products, can give rise to colored compounds through a process of oxidative condensation.

[0011] 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.

[0012] However, the implementation of these dye compositions can present a certain number of drawbacks.

[0013] 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.

[0014] 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.

[0015] Thus, there is a real need to provide a composition for coloring keratin fibers, in particular human keratin fibers such as hair, 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: - at least one compound chosen from hyaluronic acid and / or one of its derivatives and their mixtures; - at least one (bi)carbonate; - at least one fatty acid; - at least one colorant.

[0017] According to a preferred embodiment, the composition according to the invention is a composition for coloring keratin fibers, in particular hair.

[0018] The composition according to the invention makes it possible in particular to produce powerful, intense and non-selective chromatic colorations, i.e. colorations which are homogeneous along the fiber.

[0019] The composition according to the invention has improved persistence to shampoos, as well as good stability over time, in particular low evolution, or even no change in its viscosity during storage.

[0020] 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.

[0021] 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.

[0022] 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.

[0023] The invention also relates to a process for coloring hair using the composition of the invention.

[0024] 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.

[0025] By “chemical oxidizing agent” according to the invention, we mean an oxidizing agent other than oxygen in the air.

[0026] Other objects, characteristics, aspects and advantages of the invention will appear even more clearly on reading the description and the examples which follow.

[0027] In what follows, and unless otherwise indicated, the limits of a domain of values ​​are included in this domain, in particular in the expressions “between” and “ranging from ... to ...”.

[0257] In the examples which follow, all the quantities are indicated as a percentage by mass of active material (AM) relative to the total weight of the composition (unless otherwise stated). Compositions

[0258] The coloring compositions A, B and C were prepared from the ingredients whose contents are indicated in the table below (% active material):

[0259] Coloring compositions

[0262] At the time of use, each of the coloring compositions A, B and C is mixed with 1 time V2 its weight of oxidant O. Each of the mixtures is then applied to a lock of 90% permed white (BP) and natural white (BN) hair at a rate of 5g of mixture / g of hair.

[0263] After 35 minutes of exposure at 27°C, the hair is rinsed, washed with a standard shampoo and dried. Results

[0264] Colorimetric measurements were performed using a KONICA MINOLTA-3600 spectrocolorimeter (illuminant D65, angle 10°, specular component included) in the CIELab system.

[0265] Selectivity

[0266] Color selectivity is the variation in color between natural hair (NH) and permed hair (PH). Natural hair is representative of the nature of the hair at the root while permed hair is representative of the nature of the hair at the tip. Selectivity allows the homogeneity of color to be assessed throughout the hair fiber.

[0267] Selectivity is measured by:

[0268] AE, which is the color variation between natural hair and permanent hair, is obtained from the formula: . toe=

[0269] Where L* represents the intensity a* and b*, the chromaticity of natural colored hair and Lo* represents the intensity and a0* and b0* the chromaticity of permed colored hair. The lower the value of AE, the lower the selectivity and the more uniform the coloring along the hair.

[0270] [Tables2] Hair type L* a* b* AE A + O (invention) BN 28.4 4.1 10.0 0.8 BP 27.7 3.7 9.9 B + O (comparative) BN 31.7 3.2 9.9 4.1 BP 27.7 3.1 9.0 C + O (comparative) BN 29.0 3.5 9.5 3.1 BP 25.9 3.6 8.8

[0271] 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 and C+O mixtures. In other words, the A+O mixture according to the invention makes it possible to obtain locks of hair having better selectivity compared to those treated with the comparative B+O and C+O mixtures and consequently improved color homogeneity from the root to the tip of the hair.

[0272] Tenacity

[0273] The persistence of the color is evaluated in the same way. This is the difference in color AE (according to the formula above) between the colored strands before shampooing, then after having undergone 5 shampoos. The lower the AE value, the more the color persists after shampooing.

[0275] 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 and C+O mixtures.

[0276] In other words, the A+O mixture according to the invention makes it possible to obtain a homogeneous colored coating on the hair having improved persistence to shampoos compared to those treated with the comparative B+O and C+O mixtures.

[0277] Furthermore, the A+O mixture according to the invention makes it possible to obtain good sensory performances.
