ABSTRACT:
A dry sunscreen composition comprising effective amounts of octyl methoxycinnamate, octyl salicylate, homosalate, menthyl anthranilate, octocrylene, benzohenone-3, propylparaben, BHT, PVP/eicosene copolymer, octyldodecyl neopentanoate, C.sub.12-15 alcohols benzoate, titanium dioxide, and acrylates copolymer. A process for preparing a dry sunscreen composition that involves: combining effective amounts of octyl methoxycinnamate, octyl salicylate, homosalate, menthyl anthranilate, octocrylene, benzohenone-3, propylparaben, BHT, and PVP/eicosene copolymer to form a first section of ingredients; heating the first section of ingredients to a sufficient temperature with substantially constant mixing until it becomes clear and homogenous; combining effective amounts of C.sub.12-15 alcohols benzoate, and octyldodecyl neopentanoate to form a second section of ingredients by mixing at substantially ambient temperature; adding effective amounts of titanium dioxide and coloring agent to the second section of ingredients by mixing at ambient temperature until it becomes a uniform paste; adding the uniform paste to the first section of ingredients to form a homogenous fluid; milling the homogenous fluid at a sufficient temperature until a predetermined size is obtained; heating the milled homogenous fluid to a predetermined temperature; adding a first amount of acrylates copolymer to the milled homogenous fluid and mixing to form a third section of ingredients; and adding the third section of ingredients to additional acrylates copolymer and mixing until it forms a homogenous dry sunscreen composition.
