This composition consists in an aqueous dispersion D, lamellar structure lipid vesicles encapsulating an aqueous phase E; it is characterised by the fact that the lipid phase forming the layers of the said vesicles is at least partly made up of a compound as formula (I): ##STR1## wherein R represents a linear saturated on unsaturated hydrocarbonated chain containing 9 to 17 carbon atoms. The compounds (I) have the advantage that they are easily biodegradable and of very low cytotoxicity.
