摘要：
Zinc oxide compositions and methods for controlling zinc oxide particle size for sunscreen applications are provided herein. A method includes manipulating the size of multiple zinc oxide particles to be below a maximum threshold； selecting one or more media to be used in a sunscreen composition, wherein said selecting is based on the refractive index of each of the media； and integrating the manipulated zinc oxide particles into the selected media to create the sunscreen composition. A composition includes multiple zinc oxide particles, wherein each of the zinc oxide particles is (i) coated with an optical coating material and (ii) of a size that is below a maximum threshold； and a medium layer within which the zinc oxide particles are suspended, wherein the medium layer comprises a mixture of one or more media, and wherein each of the media has a refractive index below a predetermined threshold.
