Abstract

Composition comprising a glycoprotein and a coloring agent. The invention relates to a composition comprising at least one glycoprotein and at least one coloring agent.

Description

Title of the invention: Composition comprising a glycoprotein and a coloring agent.

[0001] The invention relates to a composition for treating hair comprising at least one glycoprotein and at least one coloring agent.

[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 essentially three types of hair coloring process: a) so-called permanent coloring, the function of which is to bring 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; 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.

[0006] 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.

[0007] 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.

[0008] However, the implementation of these dye compositions can present a certain number of drawbacks.

[0009] 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.

[0010] 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.

[0011] Thus, there is a real need to provide a composition for coloring 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, ease of combing and softness to the touch of keratin fibers such as hair.

[0012] These and other objectives are achieved by the present invention, which therefore relates to a composition comprising: - at least one glycoprotein; and - at least one coloring agent chosen from among oxidation dyes, direct dyes, pigments and their mixtures.

[0013] According to a preferred embodiment, the composition according to the invention is a composition for coloring keratin fibers, in particular hair.

[0014] 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.

[0015] 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.

[0016] 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.

[0017] The invention also relates to a method of coloring hair from the composition of the invention.

[0018] 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.

[0246] The present invention finally relates to the use of a composition as described above for coloring keratin fibers, and in particular hair.

[0247] The following examples serve to illustrate the invention without, however, being limiting in nature. Examples

[0248] 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

[0249] Coloring compositions A and B were prepared from the ingredients whose contents are indicated in the table below (% active material): Coloring compositions A and B

[0250] [Tables 1] A (invention) B (comparative) PSEUDOALTEROMONAS FERMENT EXTRACT 0.05 - OLEIC ACID 2.7 2.7 AMMONIUM HYDROXIDE 4.57 4.57 ETHANOLAMINE 0.63 0.63 2-AMINO-3-HYDROXYPYRID INE 0.04 0.04 HYDROXYBENZOMORPHOLI NE 0.30 0.30 HYDROXYETHYL-P-PHENYL ENEDIAMINE SULFATE 0.13 0.13 m-AMINOPHENOL 0.1 0.1 EDTA 0.20 0.20 CETEARYL ALCOHOL 16.20 16.20 OLEYL ALCOHOL 2.70 2.70 NON-IONIC SURFACTANT 3.60 3.60 ANTIOXIDANT 0.91 0.91 HYDROXYETHYL-3,4-METH YLENEDIOXYANILINE HCL 0.14 0.14 TOLUENE-2,5-DIAMINE 0.33 0.33 WATER Qs 100 Qs 100

[0251] At the time of use, each of the colour compositions A and B are mixed with 1 times its weight of oxidant O. Each of the mixtures is then applied to a strand of hair that is 90% permed white (BP) and natural white (BN) at a rate of 5g of mixture / g of hair.

[0252] After 35 minutes of exposure on a thermostatically controlled plate at 27°C, the hair is rinsed, washed with a standard shampoo and dried. Results

[0253] The colorimetric measurements were carried out using a KONICA MINOLTA-3600 spectrocolorimeter (illuminant D65, angle 10°, specular component included) in the CIELab system. a) Selectivity

[0254] 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.

[0255] Selectivity is measured by:

[0256] AE, which is the color variation between natural hair and permanent hair, is obtained from the formula:

[0257] 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.

[0258] [Tables2] Hair type L* a* b* AE A+O (invention) BN 26.5 2.4 9.3 5.3 BP 22.2 2.5 6.2 B+O (comparative) BN 26.5 3.0 10.0 7.7 BP 20.5 2.7 5.1

[0259] 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. 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 B+O mixtures.

[0260] In addition, the mixture according to the invention makes it possible to obtain good sensory performance. lb) Tenacity

[0261] The persistence of the color is evaluated in the same way. This is the color difference AE (according to the formula above) between the colored strands (BN) before shampooing, then after having undergone 5 shampoos. The lower the AE value, the more the color persists after shampooing.

[0262] [Tables3] Number of L* a* b* AE shampoos 1.5 A+O (invention) 0 26.5 2.4 9.3 5 27.8 2.4 9.6 B+O (comparative) 0 26.5 3.0 10.0 3.6 5 30.0 2.3 9.9

[0263] The hair strands 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.

[0264] 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 mixture. lc) Ease of combing and soft touch

[0265] The combability performance, i.e. detangling, and soft feel were 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 properties, “2.5 points” to average performance and “0 points” to poor performance.

[0266] To assess the ease of combing, the expert passes a comb over the strand first with the large teeth and then with the small teeth, going down from the top of the strand towards the tips, in order to feel the ease of passing the comb over the strand of hair.

[0267] Below are the scores given by the experts:

[0269] 100% of the experts (5 out of 5) judged that the A+O mixture according to the invention allowed to obtain better combing ease performance compared to the com- Comparative position B not including Pseudoalteromonas Ferment Extract.

[0270] To assess the soft touch, the expert grasps the strand between the thumb and index finger and slides his fingers along the strand from the top to the tips. He assesses whether the hair is soft, whether it has no roughness, that is, whether it does not catch the fingers.
