  • a cosmetic composition for topical application, which is in the form of a water-in-oil emulsion (inverse emulsion) comprising particles of hydrophobic silica aerogel, at least one suitably selected alkylpolyglycoside and at least one fatty alcohol of which the fatty chain is different than that of the alkylpolyglycoside, and to the
  • conventional water-in-oil inverse emulsions are very advantageous for their application properties, in particular their glide capacity, and their very characteristic sensory effect, in particular a feeling of softness and a silky effect, after application.
  • these emulsions leave a surface film and give the feeling of not penetrating into the skin.
  • the feeling of penetration is an important attribute directly linked to the effectiveness perceived by the consumer. This feeling that the product does not penetrate and/or does not penetrate sufficiently and/or does not penetrate sufficiently quickly compromises the perception of deep effectiveness (in particular for anti-aging creams where the penetration of the formula must be felt in order to convey optimal effectiveness).
  • patent US 7 514 496 describes the use of an alkylpolyglycoside, Fluidanov 20X, as an emulsifier for stabilizing water-in-oil emulsions which contain a high amount of water.
  • water-in-oil emulsions especially for formulating care creams, remains limited since, firstly, they are generally difficult to implement and, secondly, their sensory nature is often less appreciated by consumers.
  • the implementation difficulties are essentially difficulties in obtaining stable compositions especially on account of interactions, or even incompatibilities, between certain starting materials and most particularly with certain cosmetic active agents.
  • compositions in the form of a water-in- oil emulsion comprising the combination of silica aerogel particles with a suitably selected alkylpolyglycoside and a fatty alcohol of which the fatty chain is different than that of the alkylpolyglycoside constitute compositions which have good cosmetic and sensory properties, and in particular compositions which are fresh and soft on application, which are non-greasy, non-tacky and non-shiny during and after application, and which provide the skin with moisturization and persistent mattness.

  • radical R is a linear or branched C14-C24 alkyl radical

  • x denotes a value ranging from 1 to 10, preferably 1 to 4.
  • composition in accordance with the invention makes it possible to obtain a cosmetic emulsion which has good stability, and also good cosmetic and sensory properties, in particular which is fresh and soft on application, which is non-greasy, non-shiny and non- tacky during and after application, and which provides moisturization and affords a long- lasting immediate and effective mattness effect.
  • the emulsion obtained according to the invention has good stability over time, even at a temperature above ambient temperature (for example 45°C).
  • stable emulsion is generally intended to mean an emulsion which exhibits little or even no macroscopic and microscopic change (in color, in odor, in viscosity, nor any variation in pH) after storage and/or temperature change, in particular after 24 hours at a temperature of between 4°C and 50°C.
