The aim of the present research was to determine sun protection factor (SPF) values of some sunscreen formulations for their selection and use in cosmetics. Sun protection factor is determined by ultraviolet spectrophotometer analysis which is a laboratory measure of the effectiveness of sunscreen formulations. The higher the SPF, the more protection a sunscreen offers against the ultraviolet radiations causing sunburn. In vitro photo protective activity was observed in UV spectrophotometric range of 290-320 nm. Among the various sunscreen formulations SPF values were compared. The study is helpful in selection of sunscreens formulations used in cosmetics with better safety.
