METHODS FOR IMPROVING UV ABSORBANCE OF SUNSCREEN COMPOUNDS

摘要

2137143 9407460 PCTABS00032 Methods for increasing the UV absorbance of certain sunscreen agents for topical applications yielding compositions exhibiting improved sun protection factor (SPF) are disclosed. These methods comprise dissolving or suspending octyl methoxycinnamate or benzophenone-3 in certain emollient systems, e.g. high polar type materials such as ethoxylates resulting in a 15% increase in UV absorbance.
