Abstract
A novel delivery system for physical, inorganic sunscreens for use in sunscreen preparations is disclosed. One or more inorganic sunscreen agents, such as micronized zinc oxide and micronized titanium dioxide, is dispersed in a solid dispersion vehicle preferably selected from the group consisting of stearyl benzoate, behenyl benzoate and arachidyl benzoate, to thereby produce a solid dispersion of inorganic sunscreen agents for use in sun-screen preparations. The micronized sunscreens are embedded in a solid product which does not require mixing or regrinding before use. A solid formulation avoids the problems inherent in a fluid emulsion or dispersion, i.e., migration or settling out of the contents, which requires mixing and/or regrinding before use.
