Abstract
This research was done to determine the sun protection factor (SPF) of sunscreens available at commercial market, in-house developed samples involving chemical and physical sunscreens and in-house developed samples involving Schiff base compounds using ultraviolet spectrophotometry. 10 in-house topical herbal sunscreen emulsions formulation were evaluated based on the MED equation for UVB sunscreen substances.The repeatability of the method was tested. It is observed that the proposed spectrophotometric method is simple, rapid and repeatable for the in vitro determination of SPF values of sunscreen products. The proposed spectrophotometric method is simple and rapid.
