摘要：
Zinc oxide compositions and methods for applying anti-reflective coating on oxide particles for sunscreen applications are provided herein. A composition includes multiple zinc oxide particles suspended within a medium forming sunscreen composition, and coating materials applied to each of the multiple zinc oxide particles in distinct layers via a gradation based on refractive index, 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 the coating materials comprise a combination of (i) silicon dioxide, (ii) magnesium fluoride, (iii) one or more fluoropolymers, (iv) aluminum oxide, (v) zinc sulfide, and (vi) titanium dioxide.
