Definitions

  • the present invention relates to cosmetic compositions for making up the skin, in particular fluid foundations giving the skin improved color properties (fidelity and stability of the shade) without compromising hold (non-transfer).
  • compositions for making up the skin have been used for many years to improve the aesthetic appearance of the skin, in particular by reducing the visible and/or tactile irregularities of the skin. Consumers are now looking for comfortable, lighter dosage forms, with a natural make-up result, but without compromising on the make-up result (covering but natural) and its hold over time (preferably 24-hour hold).
  • foundations in the form of water-in-oil emulsions comprising silicone oils and hydrophobic treated pigments for good adhesion to the skin, and film-forming polymers to improve the hold of the deposit, but there remains the need to develop new compositions with improved color properties (fidelity and stability of the hue), without compromising on staying power (non-transfer).
  • a first object of the invention is therefore a cosmetic composition for making up keratin materials, in particular the skin, in the form of a water-in-oil emulsion, comprising, in a physiologically acceptable medium, at least: a) a vinyl polymer having at least one unit derived from carbosiloxane dendrimer, b) a silicone acrylate polymer distinct from compound a), c) one or more volatile oils, d) a C8-C22 alkyldimethicone, and e) dyestuffs surface-treated with a hydrophobic agent.
  • 'vinyl polymer having at least one unit derived from carbosiloxane dendrimer' it is meant that the vinyl polymer has a molecular side chain containing a carbosiloxane dendrimer structure.
  • the invention also relates to a cosmetic process for making up keratin materials, in particular the skin, preferably the skin of the face and/or neck, comprising the application to said keratin material of at least one cosmetic composition such as defined according to the invention.
  • the invention therefore relates in particular to a cosmetic composition for making up keratin materials, in particular the skin, in the form of a water-in-oil emulsion, comprising, in a physiologically acceptable medium, at least: a) a polymer vinyl having at least one unit derived from carbosiloxane dendrimer, b) a silicone acrylate polymer distinct from compound a), c) one or more volatile oils, d) a C8-C22 alkyldimethicone, and e) dyestuffs surface-treated with a hydrophobic agent
  • tinting the tint on application means the make-up result (tint) obtained after application.
  • the final result is generally obtained between 5 and 30 minutes. Knowing that we are looking for a color after application that is as faithful as possible to the color at the outlet of the pump (color in the mass). We will speak of 'colour fidelity' on application.
  • increase in color over time according to the invention, is meant the development of the color over the day (6 to 8 hours after application).
  • the shade can evolve (more or less) as the day progresses, depending on the stability of the film (texture) and the interaction with the skin (secretion of sebum ). Knowing that we are looking for a shade after 6 to 8 hours that is as faithful as possible to the shade after application, in other words a slight increase in shade over time. We will speak of 'colour fidelity' or 'colour stability' over time.
