Estimating the term…
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.
A composition comprising a macroscopic particle surface-treated with an inorganic particle, wherein the macroscopic particle surface-treated with an inorganic particle has a refractive index greater than a refractive index of a macroscopic particle core of said composition.
A method for embedding an inorganic particle on the surface of a macroscopic particle comprising:
A method for embedding an inorganic particle on the surface of a macroscopic particle, comprising:
