| Sumario: | The aim of this study
was to evaluate sunscreens by Dispersive X-ray Fluorescence (EDXRF) and UV-VIS spectrophotometry, to
quantify the sun protection factor (SPF) of the physical filter (micro-fine titanium dioxide) and the organics filters
(ethylhexyl methoxycinnamate and benzophenone-3), respectively, in order to obtain the total SPF. Three
formulations estimated in SPF-23 using inorganic and organic filters were prepared. The results showed that the
system EDXRF portable and UV-VIS spectrophotometry are complementary methodologies for the determination
of sunscreens, being viable for application in quality control. |
