Description

Technical Field

[0001] The invention relates to a cosmetic hair-dressing composition with detergent and exfoliating action, comprising salicylic acid or its salts, at least one anionic surfactant, at least one amphoteric or zwitterionic surfactant, solid particles and at least one specific anionic acrylic copolymer.

[0002] The invention also relates to a process for treating keratin materials, comprising at least one step of applying to said materials a composition according to the invention. Background Art

[0003] It is common practice to use detergent compositions (such as shampoos) that are essentially based on surfactants to wash and / or clean keratin materials such as hair and scalp. These compositions are applied to wet hair and the foam generated by massaging or rubbing with the hands makes it possible to remove many types of dirt originally present on the hair and scalp after rinsing with water.

[0004] However, these compositions do not always allow complete removal of dirt and / or obtaining a clean visual effect. In particular, in the case of users with a scalp that tends to be greasy and / or causes dandruff, conventional detergent compositions do not always allow complete removal of organic substances (sebum, dandruff, etc.) formed on the scalp surface and / or adhering to the hair. Therefore, there is a need to develop cosmetic compositions for treating and especially washing keratin materials that allow removal of organic materials, especially dandruff (when present) and prevent their appearance.

[0005] Furthermore, consumers are looking for cosmetic compositions containing a higher proportion of natural and biodegradable ingredients, advantageously silicone-free compositions, which have improved processing qualities and good cosmetic properties and are able to cleanse keratin materials without making them feel heavy, so as to provide good conditioning properties to the keratin fibers.

[0006] In parallel, users of cosmetic products often seek more aesthetically pleasing or even more original hair hygiene products.

[0007] Therefore, there is a real need to develop aesthetic detergent cosmetic compositions that are stable over time based on natural and / or biodegradable ingredients, preferably do not contain silicones, and that enable excellent washing properties to be obtained. These compositions must also have good processing properties, in particular in terms of the onset of foaming, the quality and amount of foam produced, and the viscosity. These compositions also advantageously impart good conditioning properties to keratin fibers, in particular in terms of feel, smoothness, slip and detangling. Summary of the invention

[0008] These objects are achieved by the present invention, a subject of which is a composition, preferably a cosmetic composition, comprising:

[0009] (i) salicylic acid and / or at least one salicylate in a total content of at least 1.5% by weight relative to the total weight of the composition,

[0010] (ii) solid particles having a number average size greater than or equal to 300 μm, the total content of which is at least 0.2% by weight relative to the total weight of the composition,

[0011] (iii) at least one anionic surfactant,

[0012] (iv) at least one amphoteric or zwitterionic surfactant, and

[0013] (v) at least one crosslinked anionic copolymer of at least one monomer A selected from vinyl carboxylic acids and at least one monomer B containing at least one α,β-ethylenic unsaturation, the monomer B being selected from monomers of the formula:

[0014] b1) CH2=CXY

[0015] wherein X indicates hydrogen, and Y indicates a group selected from -COOR, -C6H4R', -CN, -CONH2, -NHCOCH3, -CONHC(CH3)3, and -CON(CH3)2, or

[0016] X indicates CH3 and Y indicates a group selected from -COOR, -C6H4R', -CN or -CH=CH2,

[0017] R indicates a C1-C8 alkyl group or a C2-C8 hydroxyalkyl group, preferably a C1-C4 alkyl group or a C2-C4 hydroxyalkyl group,

[0018] R' indicates hydrogen, C1-C8 alkyl or C2-C8 hydroxyalkyl;

[0019] b2)CH2=CH(OCOR 1 )

[0020] Where R 1 Indicates C1-C8 alkyl and preferably C1-C4 alkyl;

[0021] b3) CH2=CH2 or CH2=CHCH3.

[0022] The composition according to the invention has excellent washing power on keratin materials. It allows to effectively remove dirt and obtain a clean visual effect. In addition, the composition according to the invention has an exfoliating effect on the scalp, which is immediately perceptible upon application, allowing to effectively remove organic substances, especially sebum and tissue fragments that are prone to dandruff. It also allows to eliminate dandruff that adheres to the keratin fibers.

[0023] The composition according to the invention also has a keratolytic action which, in combination with the exfoliating action described above, allows effectively preventing the scalp from becoming greasy again and forming dandruff. The keratin materials remain clean for longer and the average interval between two shampoo washes can be increased.

[0024] It was also noted that the hair so treated was exceptionally light, had a soft and smooth feel, and was supple, easily detangled and manageable.

[0025] It was also found that the compositions according to the invention have good processing qualities, especially a good start of foaming and a good quality and amount of foam.

[0026] The composition according to the invention has a viscosity suitable for use as a shampoo.

[0027] Furthermore, it was found that the composition according to the invention is stable over time at atmospheric pressure and 25°C.

[0028] More particularly, the solid particles remain in a homogeneous and stable suspension and no phase separation of the particles within the composition is observed. The visually stable and homogeneous suspension of these particles significantly improves the aesthetic appearance and originality of the composition according to the invention.

[0029] For the purposes of the present invention, the term "stable and homogeneous suspension" means that the particles are homogeneously dispersed in the composition, that is to say are evenly distributed within the composition, and that this homogeneous dispersion persists over time, that is to say, the particles do not float to the surface, do not sink, do not settle out and / or do not form agglomerates in the composition over time, in particular after storage for at least one month.

[0030] Advantageously, the composition comprising the suspended particles is clear.

[0031] A subject of the present invention is also a process for the treatment, especially cosmetic treatment, of keratin materials, especially human keratin materials such as the hair and the scalp, comprising at least one step of applying a composition according to the invention to said keratin materials.

[0382] Composition A is according to the invention and composition B is comparative.

[0383] The two compositions were prepared by uniformly mixing the ingredients at room temperature (25° C.) The stability of the two compositions was then evaluated by placing them in an oven maintained at a temperature of 45° C. and in the dark for two months.

[0384] After one month of storage, the appearance of composition A has not changed and it is in the form of a visually homogeneous suspension of solid particles in a transparent fluid. On the other hand, composition B shows the beginning of phase separation: particles are no longer present on the surface of the composition, an upper layer of particle-free composition is formed and the fluid is turbid.

[0385] After two months of storage at 45° C., the appearance of composition A remained unchanged: it was in the form of a visually uniform suspension of solid particles in a transparent fluid, with no visible phase separation. In the case of composition B, the phase separation increased, the thickness of the upper layer of the particle-free composition increased and the fluid was turbid.

[0386] It can thus be seen that composition A according to the invention has better stability over time than comparative composition B.
