  • the subject of the present invention is a device comprising a water-oil two-phase composi- tion containing an amphoteric surfactant and a fatty acid salt and a dispenser for dispensing the composition in foam form.
  • the invention also relates to a process for the treatment of keratin materials using the composition dispensed in foam form.
  • Cleansing cosmetic compositions are commonly used to cleanse keratin materials, in particular the skin, in particular when they are covered with makeup products such as a foundation.
  • compositions intended for cleansing keratin materials must have application qualities such as a glide effect and a foam quality and quantity, while being friendly to these keratin materials which may be relatively sensitive (eyes, mucous membranes, skin). Furthermore, they must have an appropriate viscosity in order to guarantee effective, simple and pleasant use by the consumer.
  • An objective of the present invention is to provide a cosmetic composition used in the form of a foam, in particular a non-aerosol foam, having satisfactory properties in terms of cleansing keratin materials, in particular the skin, and also a visual effect that the user finds attrac- tive.
  • composition can be obtained by preparing an oil- water two-phase composition comprising an amphoteric surfactant and an anionic surfactant chosen from fatty acid salts, and by dispensing the two-phase composition with a foam dispenser as described below.
  • the two-phase composition at rest in particular after 24 hours, has a clear interface and the aqueous phase is transparent without any apparent deposit.
  • the composition forms an emulsion and becomes uniform.
  • the foam is dense, tight, and holds well, in particular after 10 minutes and after 20 minutes following dispensing by the self-foaming pump.
