Abstract
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 organized 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.
