COSMETIC AND/OR PHARMACEUTICAL COMPOSITION CONTAINING A DISPERSION OF LIPIDIC VESICLES, PROCESS FOR THE PREPARATION OF SAID DISPERSION, AND LIPIDIC VESICLE DISPERSION

摘要

the invention relates to pharmaceutical compositions and / or cosmetic containing at least one aqueous phase dispersed in a dispersion of vesicles bounded by a membrane of a lipid phase containing at least one ionic amphiphilic lipid and / or at least one non lipid amphiphile. here, the vesicles containing an encapsulated phase.characterized by the fact that the lipid phase of at least a vesicle dispersion contains at least one compound of formula (i) in which w is - ch2oh, - ch3, - coom or - (ch2) 2 - coom, where m is h, an alkali metal or an alkali metal, in the meaning of x, y, z, v, of a hydrogen atom or a hydroxyl radical.the dispersions used have the advantage of being transparent.
