The invention relates to topical compositions comprising inorganic particles coated or embedded on the surface of macroscopic particles, methods of preparing the compositions, and uses thereof. The topical composition may be delivered and applied to a surface, thereby improving the appearance of the surface. This composition can reduce the visibility of textural imperfections, such as fine lines, wrinkles, and scars, as well as color imperfections, such as age spots and blemishes. The treatment of inorganic particles on the surface of macroscopic particles can be achieved by three methods, including mechanofusion, physical adsorption, and pre-emulsification into macroscopic particles. This invention also relates to methods of using the composition in a cosmetic or dermatological application, as well as, in an industrial application.
L'invention porte sur des compositions topiques comprenant des particules inorganiques appliquées en enrobage ou noyées sur la surface de particules macroscopiques, sur des procédés de préparation des compositions, et sur leurs utilisations. La composition topique peut être administrée et appliquée sur une surface, permettant d'améliorer ainsi l'aspect de la surface. Cette composition permet de réduire la visibilité d'imperfections texturales, telles que de fines lignes, des rides et des cicatrices, ainsi que des imperfections de couleur, telles que des lentigos séniles et des défauts d'aspect. Le traitement de particules inorganiques sur la surface de particules macroscopiques peut être obtenu par trois procédés, comprenant la mécanofusion, l'absorption physique et la pré-émulsification en des particules macroscopiques. L'invention porte également sur des procédés d'utilisation de la composition dans une application cosmétique ou dermatologique, ainsi que dans une application industrielle.
