Abstract

La présente invention concerne des compositions topiques contenant des particules solides qui sont stabilisées par encapsulation dans une matrice de silicone réticulée. Les particules stabilisées présentent un potentiel électrique suffisant pour empêcher les particules de pénétrer dans la peau. Les particules peuvent être utilisées aisément soit seules, soit en combinaison avec d'autres principes actifs de soins de la peau afin de former des compositions topiques à stabilité et performances améliorées.
