MEDIA IN THE FORM OF COMPLEX DISPERSIONS, THEIR PROCESS OF PREPARATION AND THEIR USES

摘要

The invention concerns novel media in the form of complex dispersions, method for preparing same and their uses. Said media consist of a first medium in the form of droplets wherein is dispersed a phase containing organised double layers of surfactants, preferably in the form of multilamellar vesicles, said droplets being in emulsion in a second medium called continuous phase non-miscible with the first medium. Said media can be used as base for cosmetic compositions. They can contain active principles, in particular for controlling their release and/or protecting and/or controlling their pH. They can also be used to make polymer microspheres containing an active principle. They are also useful as antigen vector.
