Description

DETERGENT AND EXFOLIATING HAIR COSMETIC COMPOSITION COMPRISING SALICYLIC ACID AND SUSPENDED PARTICLES

The present invention relates to a hair cosmetic composition with detergent and exfoliating action, which comprises salicylic acid or a salt of such an acid, at least one anionic surfactant, at least one amphoteric or zwitterionic surfactant, solid particles and at least a particular acrylic anionic copolymer.

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.

For cleaning and/or washing keratin materials such as the hair and scalp, the use of detergent compositions (such as shampoos) based essentially on surfactants is common. These compositions are applied to wet hair and the foam generated by massage or friction with the hands allows, after rinsing with water, the elimination of the various dirt initially present on the hair and scalp.

However, these compositions do not always make it possible to completely eliminate dirt and/or obtain a clean visual effect. In particular, in the case of users with a scalp that tends to be oily and/or gives rise to flaking phenomena, traditional detergent compositions do not always make it possible to completely eliminate the organic matter (sebum, dandruff, etc.) formed by the surface of the scalp and/or attached to the hair. There is therefore a need to develop cosmetic compositions intended for the treatment and in particular for washing keratin materials, which make it possible both to eliminate organic materials, in particular dandruff, when these are present, and to prevent their appearance.

Consumers are also looking for cosmetic compositions which contain greater proportions of natural and biodegradable ingredients, advantageously silicone-free compositions (" silicone-free " in English), which have improved qualities of use and good cosmetic properties, and are capable of washing keratin materials without weighing them down so as to provide good conditioning properties to the keratin fibers.

At the same time, users of cosmetic products are often looking for more aesthetic, or even more original, hair hygiene products.

There is therefore a real need to develop aesthetic detergent cosmetic compositions, stable over time, based on natural and/or biodegradable ingredients, preferably not including silicone, and making it possible to obtain excellent cleansing properties. . These compositions must also have good usage properties, in particular in terms of foam start-up, quality and quantity of foam generated, and viscosity. It is also of interest that these compositions confer good conditioning properties to the keratin fibers, particularly in terms of feel, smoothing, flexibility and detangling.

These aims are achieved with the present invention which relates in particular to a composition, preferably cosmetic, comprising:
(i) salicylic acid and/or at least one salt of salicylic acid, in a total content of at least 1.5% by weight, relative to the total weight of the composition,
(ii) solid particles having a number average size greater than or equal to 300 µm, in a total content of at least 0.2% by weight relative to the total weight of the composition,
(iii) at least one anionic surfactant,
(iv) at least one amphoteric or zwitterionic surfactant, and
(v) at least one crosslinked anionic copolymer of at least one monomer A chosen from vinyl carboxylic acids and at least one monomer B having at least one α, β-ethylenic unsaturation chosen from the monomers of the following formulas:
b1) CH ₂ =CXY
_{with ​ ​ ​ ​ ​ ​ 2} , or
X designates CH ₃ and Y designates a group chosen from -COOR, -C ₆ H ₄ R', -CN or -CH=CH ₂ ,
R designating a C ₁ -C ₈ alkyl group or a C ₂ -C ₈ hydroxyalkyl group, preferably a C ₁ -C ₄ alkyl group or a C ₂ -C _{4 hydroxyalkyl group,}
R' designating hydrogen, a C ₁ -C ₈ alkyl group or a C ₂ -C ₈ hydroxyalkyl group.
b2) CH ₂ =CH(OCOR ¹ )
with R ¹ denotes a C ₁ -C ₈ alkyl group, preferably C ₁ -C ₄ .
b3) CH ₂ =CH2 or CH ₂ =CHCH ₃ .

The composition according to the invention has excellent washing power for keratin materials. It allows you 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, perceptible upon application, which makes it possible to effectively eliminate organic matter, in particular sebum and tissue fragments likely to form dandruff. It also helps eliminate dandruff attached to keratin fibers.

The composition according to the invention also has a keratolytic action, which in combination with the exfoliating effect described above makes it possible to effectively prevent the re-greasing of the scalp and the formation of dandruff. Keratin materials stay clean longer and the average interval between two shampoos can be extended.

It has also been noted that hair treated in this way is particularly light, soft to the touch, smooth to the touch, supple, easy to detangle and disciplined.

In addition, it has been observed that the composition according to the invention has good qualities of use, in particular good foam start-up, good quality and a good quantity of foam.

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

Furthermore, it has also been found that the composition according to the invention is stable over time, at atmospheric pressure and at 25°C.

More particularly, the solid particles remain in homogeneous and stable suspension, and no phenomenon of phase shift of the particles within the composition was observed. The visually stable and homogeneous suspension of these particles significantly improves the aesthetics and originality of the composition according to the invention.

By “stable and homogeneous suspension”, within the meaning of the invention, it is understood that said particles are dispersed homogeneously in the composition, that is to say distributed homogeneously within the composition, and that this homogeneous dispersion persists over time, that is to say that the particles do not float, do not sink, do not settle and/or do not form agglomerates in the composition over time, in particular after at least one month of storage.

Advantageously, the composition comprising the suspended particles is clear.

Composition A is in accordance with the invention, composition B is comparative.

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

After one month of storage, the appearance of composition A has not changed; it is in the form of a visually homogeneous suspension of solid particles in a clear fluid. For composition B, on the other hand, the beginning of a phase shift is observed: there are no more particles on the surface of the composition, an upper layer of composition devoid of particles has formed and the fluid is cloudy.

After two months of storage at 45°C, the appearance of composition A has still not changed: it is in the form of a visually homogeneous suspension of solid particles in a clear fluid and there is no phase shift phenomenon. is visible. With regard to composition B, the phase shift has increased, the thickness of the upper layer of composition devoid of particles has increased and the fluid is cloudy.

It therefore appears that composition A according to the invention has better stability over time than comparative composition B.
