Participants

Reaction Steps

The methods of the present invention were used to produce complexes comprising zinc oxide and avobenzone (Parsol 1789 was the source for avobenzone) (see FIGS. 3A-C). Approximately 1 g zinc oxide was mixed with about 3.8 g Parsol 1789 in 250 mL anhydrous alcohol (mixture of methanol and isoppropanol). Mixing occurred in a sealed glass jar on a magnetic stirrer at ambient temperature. Complexes were visible within nine days of mixing. The complexes were isolated by filtering (via a Buchner funnel) after about 21 days of mixing, and the yield was approximately 92.5%. The zinc oxide/avobenzone complexes formed had no observable melting point, and IR spectroscopy confirmed that the complexes contained zinc oxide and avobenzone.
