Abstract
The present invention relates to a composition comprising a mixture: of hydrophobic silica aerogel particles having a specific surface area per unit of mass (S) ranging from 500 to 1500 m/g and a size expressed as the volume-average diameter (D[0.5]) ranging from 1 to 1500 μm, and of at least one first linear silicone oil having a viscosity greater than 50 mm/s and of at least second and third linear silicone oils having a viscosity less than or equal to 50 mm/s. The present invention also relates to a cosmetic composition comprising a mixture: of hydrophobic silica aerogel particles having a specific surface area per unit of mass (S) ranging from 500 to 1500 m/g and a size expressed as the volume-average diameter (D[0.5]) ranging from 1 to 1500 μm, and of at least one first linear silicone oil having a viscosity less than 10 mm/s and of at least one second linear silicone oil having a viscosity greater than or equal to 10 mm/s. The mixture of silica aerogel particles and linear silicone oils makes it possible to obtain compositions that are comfortable and soft on application, having mattifying and soft-focus properties.
