Abstract
The present invention relates to a cosmetic and/or dermatological composition comprising, in a physiologically acceptable medium: a) at least some hydrophobic aerogel particles, b) at least some perlite particles, c) at least some particles that absorbs sebum. The invention also relates to a process for making the skin matt and/or for reducing its shine.
Claims24
A cosmetic and/or dermatological composition comprising, in a physiologically acceptable medium:
- a) hydrophobic silica aerogel particles, wherein the hydrophobic silica aerogel particles have a size, expressed as the volume-mean diameter, ranging from 5 to 25 μm and a specific surface area per unit of mass ranging from 200 to 1500 m2/g, and the hydrophobic silica aerogel particles represent from 0.1% to 10% by weight relative to the total weight of the composition,
- b) perlite particles different than the particles a) and c) in an amount of 0.1% to 10% by weight relative to the total weight of the composition,
- c) particles that absorb sebum and which are different than the particles a) and b) and being chosen from the group of silica powders, powders of acrylic polymers and mixtures thereof, in an amount of 0.1% to 20% by weight relative to the total weight of the composition, and
- d) 30 to 95% by weight of water, and
- wherein the composition comprising the combination of the a) hydrophobic silica aerogel particles, b) perlite particles and c) particles chosen from the group of silica powders, powders of acrylic polymers and mixtures provides less skin shine as compared to compositions containing each of the particles a), b) and c) alone in the same amount as the combination of the particles a), b) and c).
