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.

Dispersion of lipidic spherules

The invention relates to a composition consisting of a dispersion in an aqueous medium D of niosome and/or liposome spherules, within which an aqueous phase E is encapsulated, at least one portion of the spherules being niosomes; the lipids forming spherules constituting from 2 to 10% of the weight of the composition; in at least one of the phases E and D there is dissolved at least one water-soluble polyamide polymer having a molecular weight between 1,000 and 200,000, at a concentration of 0.01 to 5% by weight relative to the total weight of the composition. Usable in cosmetics or pharmaceuticals.
