ANTI-REFLECTIVE COATING ON OXIDE PARTICLES FOR SUNSCREEN APPLICATIONS

摘要

Zinc oxide compositions and methods for applying anti-reflective coating on oxide particles for sunscreen applications are provided herein. A method includes selecting one or more coating materials to be applied to zinc oxide particles in a sunscreen composition, wherein said selecting is based on optical properties of the coating materials, wherein the optical properties comprises at least the refractive index of each of the coating materials, and applying the selected coating materials to the zinc oxide particles to create the sunscreen composition. A composition includes multiple zinc oxide particles suspended within a medium forming sunscreen composition, and one or more coating materials applied to each of the zinc oxide particles, wherein each of the coating materials has a refractive index that is between the refractive index of air and the refractive index of zinc oxide, and wherein at least one of the coating materials incorporates a textured surface.
