Description

Cosmetic composition comprising a superabsorbent polymer and a silane The present application relates to a cosmetic composition, in particular for topical application, comprising at least one aqueous phase, at least one superabsorbent polymer and a silane, and to the use of said composition in the fields. cosmetic and dermatological, in particular for the care, the treatment of keratin materials. In the field of cosmetics, and more particularly in the field of skincare, photoprotection or make-up, it is known from US patent application 2010033018 to introduce in the type of emulsion oil-water emulsion or water-in oil superabsorbent water polymers because they give the textures interesting sensory effects such as freshness, and / or a reduction of stickiness.

This type of galenic nonetheless has the defect of having a poorly homogeneous spread on the skin, which can lead to a linting phenomenon (particle formation) after application. This defect is unacceptable particularly when the composition contains in addition a powdery material. There is therefore a need to make stable cosmetic compositions such as oil-in-water or water-in-oil emulsions containing a superabsorbent polymer, having a uniform application to the skin, and not linting after application. The Applicant has discovered that cosmetic compositions comprising an aqueous phase, a superabsorbent polymer and a silane have textures having good sensory properties, have a homogeneous spread on keratin materials such as the skin and do not liquefy after application. Thus, the subject of the present invention is a cosmetic composition, especially for topical application, comprising at least one aqueous phase, at least one superabsorbent polymer and at least one silane and / or its oligomers. The invention also relates to a composition, comprising an aqueous phase, obtainable from one or more superabsorbent polymers, and one or more silanes and / or their oligomers.

Since the composition of the invention is intended for application to the skin or superficial body growths, it comprises a physiologically acceptable medium, that is to say a medium that is compatible with all keratinous substances such as the skin, the nails, the mucous membranes. and keratinous fibers (such as hair, eyelashes).

The composition according to the invention has the advantage of having a very soft texture, non-sticky and fresh on application, so very pleasant to use, while having a homogeneous and easy spreading on keratin materials and not linting after application. The subject of the invention is also a process for the cosmetic treatment of keratinous substances consisting in applying to the keratin materials a composition as defined above. The subject of the invention is also the use of said composition in the cosmetic or dermatological field, and in particular for the care, the protection and / or the make-up of the skin of the body or of the face, or for the care of the hair . In what follows, the expression "at least one" is equivalent to "one or more" and, unless otherwise indicated, the boundaries of a domain of values are included in this field.

Superabsorbent Polymers The term "superabsorbent polymer" is intended to mean a polymer which is capable, in its dry state, of spontaneously absorbing at least 20 times its own weight of aqueous fluid, in particular water and especially distilled water.

These polymers have a great capacity for absorption and retention. water and aqueous fluids. After absorption of the aqueous liquid, the polymer particles so imbibed with aqueous fluid remain insoluble in the aqueous fluid and thus retain their individualized particulate state. The superabsorbent polymer can have a water absorption capacity ranging from 20 to 2000 times its own weight (ie 20 g to 2000 g absorbed water per gram of absorbent polymer), preferably from 30 to 1500 times, and better from 50 to 1000 times. These water absorption characteristics are defined under normal conditions of temperature (25 ° C) and pressure (760 mmHg or 100000 Pa) and for distilled water.

The value of the water absorption capacity of a polymer can be determined by dispersing 0.5 g of polymer (s) in 150 g of a water solution, while waiting for 20 minutes, filtering the non-aqueous solution. absorbed on a 150 μm filter for 20 minutes and weighing the unabsorbed water.
