Embedding oxide particles within separate particles for sunscreen applications
Zinc oxide compositions and methods for embedding oxide particles in a separate suspension particle for sunscreen applications are provided herein. A method includes reducing the size of each of multiple zinc oxide particles in accordance with a predetermined range; selecting one or more suspension particles to be utilized in conjunction with the multiple zinc oxide particles in a sunscreen composition, wherein each of the one or more suspension particles is larger in size than each of the multiple zinc oxide particles, and wherein said selecting is based on the refractive index of each of the one or more suspension particles; and embedding the multiple zinc oxide particles into the one or more suspension particles to create the sunscreen composition.
