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 compositions containing at least one dispersion, in an aqueous dispersion phase, of vesicles delimited by a lipid phase membrane containing at least one ionic amphiphilic lipid and / or at least one amphiphilic lipid non- ion, said vesicles containing an encapsulated phase, characterized in that the lipid phase of the vesicles at least one dispersion contains at least one compound of formula (I) wherein W is -CH 2 OH, -CH 3, -COOM or - ( CH2) 2-COOM, where M is H, alkali metal or alkaline earth metal, depending on the meanings of X, Y, Z and V, taken from a hydrogen atom or a hydroxyl radical. The dispersions used have the advantage of being transparent.
