Description

Title of the invention: Composition comprising hyaluronic acid and / or one of its derivatives, an anionic surfactant, an alkaline agent, a colorant, a solid fatty alcohol and a liquid fatty alcohol.

[0001] The invention relates to a composition for treating hair comprising hyaluronic acid and / or one of its derivatives, at least one anionic surfactant, at least one alkaline agent, at least one colorant, at least one liquid fatty alcohol and at least one solid fatty alcohol.

[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] There are basically three types of hair coloring process:

[0006] 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;

[0007] 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;

[0008] c) temporary coloring which results in a modification of the natural color of the hair which lasts from one shampoo to another and which serves to enhance or correct a shade already obtained. It can also be likened to a “make-up” process.

[0009] 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 by an oxidative condensation process.

[0010] 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.

[0011] However, the implementation of these dye compositions can present a certain number of drawbacks.

[0012] 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.

[0013] 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.

[0014] 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.

[0015] The formulation of environmentally friendly cosmetic products, i.e. those whose design and development take environmental issues into account, is becoming a major concern to help meet global challenges.

[0016] It is therefore essential to offer more sustainable compositions that can respond to these environmental challenges.

[0017] 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, without degradation of the cosmetic properties, in particular which is capable of leading to good color build-up, 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 qualities of use and retaining good sensory performance, in particular in terms of shine, flexibility, smoothness, ease of combing such as disentangling and softness to the touch of keratin fibers such as hair.

[0018] 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 anionic surfactant; - at least one alkaline agent; - at least one colorant; - at least one liquid fatty alcohol and at least one solid fatty alcohol, the total content of liquid fatty alcohol(s) and solid fatty alcohol(s) being greater than or equal to 5% by weight of the total weight of the composition.

[0019] According to a preferred embodiment, the composition according to the invention is a composition for coloring keratin fibers, in particular hair.

[0020] 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. It also makes it possible to achieve different shades in a very wide range of colors. In addition, it allows good color build-up.

[0021] This composition also makes it possible to cover depigmented keratin fibers, such as white hair, particularly well.

[0022] Furthermore, the composition according to the invention has good qualities of use, in particular a creamy texture allowing rapid and easy mixing with an oxidizing composition where appropriate, easy and homogeneous distribution over the entire head of hair.

[0023] 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.

[0024] The composition according to the invention also makes it possible to achieve good cosmeticity, particularly in terms of shine, softness, suppleness, a more natural and softer feel and easier combing, while preserving the integrity of the fiber.

[0025] The invention also relates to a process for coloring hair using the composition of the invention.

[0026] 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.

[0027] By “chemical oxidizing agent” according to the invention, we mean an oxidizing agent other than oxygen in the air.

[0028] Other objects, characteristics, aspects and advantages of the invention will appear even more clearly on reading the description and the examples which follow.

[0029] 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 ...”.

[0253] The present invention finally relates to the use of a composition as described above for coloring keratin fibers, and in particular hair.

[0254] The following examples serve to illustrate the invention without, however, being limiting in nature. Examples

[0255] In the following examples, all quantities are indicated as a percentage by mass of active ingredient (AI) relative to the total weight of the composition (unless otherwise stated). Compositions

[0256] The coloring compositions Al, Bl, A2, B2, A3, B3, A4, B4 were prepared from the ingredients whose contents are indicated in the table below (% active material):

[0257] 1. Coloring compositions Al and Bl (example 1)

[0258] [Tables 1] Al (invention) Bl (comparative) OLEIC ACID 2.70 2.70 AMMONIUM HYDROXIDE 4.57 4.57 ETHANOLAMINE 0.63 0.63 2-AMINO-3-HYDROXYPYRIDIN E 0.04 0.04 HYDROXYBENZOMORPHOLIN E 0.30 0.30 ANTIOXIDANT 0.91 0.91 HYDROXYETHYL-P-PHENYLEN EDIAMINE SULFATE 0.13 0.13 m-AMINOPHENOL 0.05 0.05 EDTA 0.20 0.20 CETEARYL ALCOHOL 16.20 16.20 OLEYL ALCOHOL 2.70 2.70 NON-IONIC SURFACTANT 3.60 3.60 SODIUM HYALURONATE 0.05 - HYDROXYETHYL-3,4-METHYL ENEDIOXYANILINE HCL 0.14 0.14 TOLUENE-2,5-DIAMINE 0.33 0.33 WATER Qs 100 Qs 100

[0259] At the time of use, each of the coloring compositions Al and Bl are mixed with 1 time U2 its weight of oxidant O. Each of the mixtures is then applied to a strand of 90% permed white (BP), natural white (BN) and / or moderately sensitized (SA20) hair at a rate of 5g of mixture / g of hair.

[0260] After 35 minutes of exposure at 27°C, the hair is rinsed, washed with a standard shampoo and dried. Results

[0261] Colorimetric measurements were performed using a KONICA MINOLTA-3600 spectrocolorimeter (illuminant D65, angle 10°, specular component included) in the CIELab system. Selectivity

[0262] Color selectivity is the variation in color between natural hair and permed hair. 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.

[0263] Selectivity is measured by:

[0264] AE, which is the color variation between natural hair and permanent hair, is obtained from the formula:

[0265] 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.

[0266] [Tables2] Hair type L* a* b* AE Al + O (invention) BN 27.6 2.2 9.5 4.5 BP 23.7 2.3 7.1 B1 + O (comparative) BN 26.5 3.0 10.0 7.7 BP 20.5 2.7 5.1

[0267] The locks of hair treated with the Al+O mixture according to the invention have a much lower AE value than those treated with the comparative B l+O mixture. In other words, the Al+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 l+O mixture and consequently improved color homogeneity from the root to the tip of the hair. Tenacity

[0268] 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 (BN) before shampooing, then after having undergone 5 shampoos. The lower the value of AE, the more the color persists after shampooing.

[0269] [Tables3] Number of shampoos L* a* b* AE Al + O (invention) 0 27.6 2.2 9.5 0.9 5 28.3 2.5 9.1 B1 +O (comparative) 0 26.5 3.0 10.0 3.6 5 30.0 2.3 9.9

[0270] The locks of hair treated with the Al+O mixture according to the invention have a much lower AE value than those treated with the comparative B1+0 mixture.

[0271] In other words, the Al+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 l+O mixture. Ease of combing

[0272] The combing ease performance, i.e. detangling, was evaluated by 5 experts, on moderately sensitized hair (SA20). Each of the 5 experts rated each of the strands, awarding “5 points” to very good combing properties, “2.5 points” to moderately good combing properties and “0 points” to combing properties rated as poor.

[0273] To assess the ease of combing, the expert passes a comb over the lock first with the large teeth then with the small teeth, going down from the top of the lock towards the tips, in order to feel how easily the comb passes over the lock of hair.

[0274] Below are the scores awarded by the experts: Combing Al+O (Invention) B1 + O (Comparative) Expert 1 3.5 2 Expert 2 3.5 2.5 Expert 3 3.5 2.5 Expert 4 4 3 Expert 5 3 2.5 Average 3.5 2.5

[0276] 100% of the experts (5 out of 5) judged that the Al+O mixture according to the invention allowed to obtain better combability performance compared to the comparative B1+0 mixture not including sodium hyaluronate.
