Abstract

The present invention relates to a composition, especially cosmetic composition, in particular for caring for keratin materials, comprising: at least one particulate cellulosic compound; at least hydrophobic silica aerogel particles; and at least one semicrystalline polymer containing at least one alkyl acrylate chain. It also relates to a cosmetic process for caring for keratin materials comprising the application to the keratin materials of said composition.

Claims (16)

1 . Composition comprising:

at least one particulate cellulosic compound;

at least hydrophobic silica aerogel particles; and

at least one semicrystalline polymer containing at least one alkyl acrylate chain.

2 . Composition according to claim 1 , wherein the particulate cellulosic compound(s) are chosen from cellulosic compounds in the form of spheres, cellulosic compounds in the form of fibres, and mixtures thereof.

3 . Composition according to claim 1 , wherein the particulate cellulosic compound(s) are chosen from spherical cellulose beads and/or microcrystalline celluloses in the form of spheres.

4 . Composition according to claim 1 , wherein the content of particulate cellulosic compound(s) ranges from 0.1% to 10% by weight, relative to the total weight of the composition.

5 . Composition according to claim 1 , wherein the hydrophobic silica aerogel particles are particles of silylated silica aerogel (INCI name: silica silylate).

6 . The composition as claimed in claim 1 , wherein the content of hydrophobic silica aerogel particles ranges from 0.05% to 5% by weight, relative to the total weight of the composition.

7 . Composition according to claim 1 , wherein the semicrystalline polymer(s) containing at least one alkyl acrylate chain are chosen from the homopolymers obtained by polymerization of a monomer chosen from alkyl acrylates and alkyl methacrylates and from the copolymers obtained by copolymerization of a monomer chosen from alkyl acrylates and alkyl methacrylates with a hydrophilic monomer, and mixtures thereof.

8 . Composition according to claim 1 , wherein the semicrystalline polymer(s) containing at least one alkyl acrylate chain are chosen from a polystearyl acrylate, a polybehenyl acrylate, a behenyl acrylate/2-hydroxyethyl acrylate copolymer, a stearyl acrylate/2-hydroxyethyl acrylate copolymer, and one of the mixtures thereof.

9 . Composition according to claim 1 , wherein the content of semicrystalline polymer(s) containing at least one alkyl acrylate chain ranges from 0.5% to 3% by weight, relative to the total weight of the composition.

10 . Composition according to claim 1 , further comprising at least one non-volatile hydrocarbon-based oil.

11 . Composition according to claim 1 , comprising at least one gelling agent.

12 . Composition according to claim 1 , comprising at least one nonionic surfactant.

13 . Cosmetic process for caring for keratin materials, comprising at least one step of applying to said keratin materials a composition as defined in claim 1 .
