Abstract

The present invention relates to a cosmetic composition for making up and/or caring for the skin and/or the lips, comprising, in a physiologically acceptable medium, at least one oil, which is preferably non-volatile, at least hydrophobic silica aerogel particles, at least one hydrocarbon-based resin having a number-average molecular weight of less than or equal to 10 000 g/mol, the said composition comprising less than 5% by weight of water relative to the total weight of the composition, and preferably being anhydrous.

First claim

The invention claimed is:

1. A composition comprising, in a physiologically acceptable medium, at least one fatty phase comprising:
an oil;
hydrophobic silica aerogel particles; and
a hydrocarbon-based indene resin;
wherein the composition comprises less than 5% by weight of water relative to the total weight of the composition.

2. The composition according to claim 1 , wherein the hydrophobic silica aerogel particles have a specific surface area per unit of mass (S M ) ranging from 500 to 1500 m 2 /g and a size expressed as the volume-mean diameter (D[0.5]) ranging from 1 to 1500 μm.

3. The composition according to claim 1 , wherein the hydrophobic aerogel particles have an oil absorption capacity, measured at the wet point, ranging from 5 to 18 ml/g of the particles.

4. The composition according to claim 1 , wherein the hydrophobic aerogel particles have a tapped density ranging from 0.02 g/cm 3 to 0.10 g/cm 3 .

5. The composition according to claim 1 , wherein the hydrophobic silica aerogel particles are hydrophobic silica aerogel particles that are surface-modified with trimethylsilyl groups.

6. The composition according to claim 1 , wherein the hydrophobic aerogel particles are present in an active material content ranging from 0.1% to 15% by weight, relative to the total weight of the composition.

7. The composition according to claim 1 , wherein the hydrocarbon-based indene resin is selected from hydrogenated indene/methylstyrene/styrene copolymers.

8. The composition according to claim 1 , wherein the hydrocarbon-based indene resin is present in a content ranging from 1% to 45% by weight, relative to the total weight of the composition.

9. The composition according to claim 1 , wherein the composition comprises at least one hydrocarbon-based block copolymer.

10. The composition according to claim 9 , wherein the hydrocarbon-based block copolymer comprises at least one styrene block and at least one block comprising units selected from the group consisting of butadiene, ethylene, propylene, butylene, isoprene, hydrogenated diblock copolymers of styrene-ethylene/propylene, of styrene-ethylene/butadiene and of styrene-ethylene/butylene, hydrogenated triblock copolymers of styrene-ethylene/butadiene-styrene, of styrene-butylene/ethylene-styrene, of styrene-isoprene-styrene and of styrene-butadiene-styrene, and mixtures thereof.

11. The composition according to claim 9 , wherein the hydrocarbon-based block copolymer is a mixture of a styrene-butylene/ethylene-styrene triblock hydrogenated copolymer and a styrene-ethylene/butylene diblock copolymer.

12. The composition according to claim 9 , wherein the hydrocarbon-based block copolymer is present in the composition in a content ranging from 0.1% to 15% by weight relative to the total weight of the composition.

13. The composition according to claim 1 , wherein the composition comprises at least one wax.

14. The composition according to claim 13 , wherein the composition comprises a total content of the wax ranging from 0.1% to 15% by weight, relative to the total weight of the composition.

15. The composition according to claim 1 , wherein the oil is a non-volatile oil selected from the group consisting of:
hydrocarbon-based oils selected from apolar hydrocarbon-based oils selected from the group consisting of polybutenes, polyisobutenes, hydrogenated polyisobutenes, polydecenes, hydrogenated polydecenes, and mixtures thereof, and polar hydrocarbon-based oils selected from the group consisting of hydrocarbon-based oils from plants or of plant origin, ester oils, fatty alcohols comprising 12 to 26 carbon atoms, fatty acids comprising 12 to 26 carbon atoms and vinylpyrrolidone copolymers, and mixtures thereof,
silicone oils selected from the group consisting of linear or branched polydimethylsiloxanes, non-volatile polydimethylsiloxanes and/or polydimethylsiloxanes comprising alkyl, alkoxy or phenyl groups, which are pendent or at the end of the silicone chain, these groups comprising 2 to 24 carbon atoms,
fluoro oils,
and mixtures thereof.

16. The composition according to claim 15 , wherein the total content of the non-volatile oil ranges from 15% to 90% by weight, relative to the total weight of the composition.

17. The composition according to claim 1 , wherein the composition is free of nanometric-sized silica.

18. The composition according to claim 1 , wherein the composition is free of hydrophobic-treated fumed silica.

19. The composition according to claim 1 , wherein the composition comprises at least one additional compound selected from the group consisting of dyestuffs, dextrin esters, pasty fatty substances, film-forming polymers, block ethylenic copolymers, organogelling agents, hydrocarbon-based polyamides, silicone polyamides, polyurethanes, semi-crystalline polymers, additional fillers, active agents, and mixtures thereof.
