ABSTRACT:
Novel Sunscreen compositions are demonstrated which are either water dispersible or waterproof without the inclusion of PABA, PABA derivatives, oxybenzone (Benzophenone 3), and any auxilliary UV-B or UV-A screen be they water or oil soluble. This is done by the use of p-methoxy-2-ethyl-hexyl cinnamate (Parsol MCX) and 1-(4-methoxylphenyl)-3-(4 tert-butyl-phenyl) propan 1-3 dione (Parsol 1789) as the only absorbers present.
The only common element in all the sunscreen composition demonstrated is the presence of the neopentanoate ester having the strutural formula ##STR1## which is used for emolliency; moisturization and increasing the SPF factors. The unusually high SPF factors are a result of these unique compositions.
