Description

Cosmetic composition comprising a sulfonic polymer, a hydrophobic polysaccharide and a silicone surfactant

The present invention relates to especially cosmetic compositions comprising at least one polysaccharide modified with hydrophobic chains, at least one sulphonic polymer and at least one acrylic polymer and / or an oxyethylenated silicone surfactant, as well as the use of these compositions in a process of treatment of keratinous substances of human beings.

More particularly, the compositions of the invention are intended for caring for and / or making up keratin materials.

For the purposes of the invention, the term "keratin materials" is intended to mean, for example, the skin, the mucous membranes, the lips, the scalp, the eyelashes, the eyebrows and the hair.

The subject of the present invention is a composition, in particular of the oil-in-water emulsion type, of fluid to viscous consistency, intended for the care, treatment or makeup of keratin materials such as skin, nails, eyelashes, eyebrows. , hair or lips.

This composition can be a foundation, a blush, an eye shadow, a concealer, a lipstick, a mascara, a body makeup product, when it comes in colored form or be a cream skin care product, a conditioner, a shampoo, a sunscreen or skin-coloring cream or a dermatological ointment, when it is in uncoloured form. These compositions have various textures ranging from fluid to solid and generally contain oils and pulverulent materials optionally coloring. One of the difficulties encountered by the users is to be able to evenly spread the composition, for example the foundation on the entire surface of the face so as to evenly distribute the product. Very thick or solid texture compositions are difficult to spread because of their high viscosities. Fluid texture compositions are not always appropriate for achieving uniform makeup, leaving no visible marks on the skin, especially because of their poor spread over the entire surface of the face to make up.

A too fluid composition is difficult to apply to keratin materials. Such a composition flows from the keratin materials, especially the skin, on which it is applied. Its application on the keratin materials that one wishes to treat lacks precision and thus makes its use unattractive. It is therefore often sought to formulate compositions having a sufficiently thickened texture to allow easy handling of the product, both when taking the composition out of its packaging, but also when it is applied to the skin and / or the materials. keratinous, but not so strong that it can no longer be sampled or spread homogeneously.

It is known to introduce thickeners into the outer phase of the emulsions, or to increase the internal phase content dispersed to obtain the desired viscosity. However, during their industrial manufacture, it is then necessary to have an apparatus sufficiently powerful to allow a homogeneous dispersion of the internal phase in the thickened continuous phase. Such devices are, however, substantially more expensive. Moreover, the presence of pulverulent materials such as pigments or fillers, and / or the presence of active agents, has the disadvantage of destabilizing the compositions, in particular the emulsions, and / or of significantly modifying the viscosity of the phase which causes them. includes. There is therefore a need for stable cosmetic compositions having a viscosity sufficiently high to allow satisfactory handling of the product, especially during its application,

The inventors have shown that it is possible to obtain such a composition by combining at least one hydrophobic modified polysaccharide, at least one sulphonic polymer, at least one acrylic polymer and / or an oxyethylenated silicone surfactant. Surprisingly, the inventors have observed that the compositions exhibit good stability over time, especially after storage for 2 months at room temperature (25 ° C.) and at 45 ° C.). The compositions do not phase out and the viscosity does not change or little over time.

In addition, this composition makes it possible to incorporate assets and / or charges: the presence of the charges and / or the assets does not modify the stability. In addition, the composition according to the invention when it is applied to keratinous substances, and in particular to the skin, does not have a sticky feeling, it leaves the skin with a velvety, soft, non-greasy finish.

More specifically, the present invention relates to a composition, comprising, in an aqueous physiologically acceptable medium, i) at least one polymer containing a sulfonic group, ii) at least one hydrophobic modified polysaccharide and iii) at least one (meth) acid polymer. acrylic and / or a silicone surfactant chosen from oxyethylenated polydimethylsiloxanes. According to the invention, the viscosity of the compositions can vary from 5 to 100 Poises, preferably from 10 to 50 Poises at 25C. The composition according to the invention is in particular a cosmetic composition.

The present invention also relates to a method of non-therapeutic treatment care or makeup of keratin materials comprising the application on said keratin materials of a composition according to the invention. Advantageously, such a method is intended for care or make-up of the skin. By "at least one" is understood according to the invention "one, two or more". Hydrophobic modified polysaccharide

The composition according to the invention comprises at least one hydrophobic modified polysaccharide, preferably a fructan. Fructans or fructosans are oligosaccharides or polysaccharides comprising a sequence of anhydrofructose units optionally associated with a plurality of different saccharide residues of fructose. The fructans can be linear or branched. The fructans can be products obtained directly from a plant or microbial source or products whose chain length has been modified (increased or reduced) by fractionation, synthesis or hydrolysis in particular enzymatic. The fructans generally have a degree of polymerization of from 2 to about 1000 and preferably from 2 to about 60.

There are 3 groups of fructans. The first group corresponds to products whose fructose units are mostly linked by β-2-1 bonds. These are essentially linear fructans such as inulin.

The second group also corresponds to linear fructoses but the fructose units are essentially linked by β-2-6 bonds. These products are levanes.

The third group corresponds to mixed frucans, that is to say having sequences β-2-6 and β-2-1. These are essentially branched fructans than graminans. The fructans used preferably in the compositions according to the invention are the inulins. Inulin can be obtained for example from chicory, dahlia or Jerusalem artichokes. Preferably, the inulin used in the composition according to the invention is obtained for example from chicory.

In particular, they are obtained by grafting hydrophobic chains onto the hydrophilic backbone of the fructan.

The hydrophobic chains capable of being grafted onto the main chain of the fructan can in particular be linear or branched hydrocarbon chains, saturated or unsaturated, having from 1 to 50 carbon atoms, such as the alkyl, arylalkyl, alkylaryl or alkylene groups; divalent cycloaliphatic groups or organopolysiloxane chains.
