Abstract
Cosmetic or pharmaceutical composition consisting of a dispersion in an aqueous medium D of lipidic spherules to the lipidic phase of which there is associated at least one lipoprotide free of sulfhydryl function selected amongst the mono- or polyacylated derivatives of amino acids or of polypeptides, wherein the acyle residue R--CO comprises a C.sub.13 -C.sub.19, hydrocarbonated chain R, at least one of the functions which connects the polypeptidic chain or the amino acid residue to the lipophilic chain being an amide function, the carboxylic functions of the polypeptidic chain or of the amino acid residue being partially or completely neutralized by means of one or a plurality of alkaline cations, an ammonium ion or a substituted ammonium derived from an amine, said lipoprotide or lipoprotides being present in a ratio from 1 to 15% by weight based on the total weight of said lipidic phase.
