The present invention relates to microcapsules with an aqueous core containing at least one water-soluble cosmetic or dermatological active principle, and with a polymeric and/or waxy envelope, in which the said envelope consistsof at least one polymer chosen from polycaprolactone, poly(3-hydroxybutyrate), poly(ethylene adipate), poly(butylene adipate), cellulose esters of at least one C1-C4 carboxylic acid, copolymers of styrene and of maleic anhydride, copolymers of styrene and of acrylic acid, styrene-ethylene/butylene-styrene block terpolymers, styrene-ethylene/propylene-styrene block terpolymers and terpolymers of ethylene, of vinyl acetate and of maleic anhydride, and/orof at least one wax chosen from beeswax, polyglycerolated beeswax, hydrogenated plant oils, paraffin with a melting point above 45° C., and silicone waxes. |
