Abstract

This study evaluated SPF (Sun Protection Factor) of various quntity and kind of sunscreen ingredients which is used in O/W and W/O emulsion by systematic and quantitative approach. Octylmethoxycinnamate(OMC), Buthylmethoxydibenzoylmethan (BMDM), Octocrylene (OC), Octylsalicylate(OS), Octyl Triazone (OT), Titanium dioxide (TD) are used for the experiment. As a result, when different chemical sunscreen ingredients are added to OMC, the synergy effect of SPF was high in order of BMDM, OC, OS, OT. There was no significant difference in O/W and W/O emulsions. It can be a guide to use sunscreen ingredients effectively when the relation between the results of in vitro SPF and in vivo SPF is comprehended.
