This study aims to test anti-UV activity, determine the SPF, and perform an irritation test on human skin from Ricinus communis leaf extract. The anti-UV and SPF values were determined using a UV-Vis Spectrophotometer. Furthermore, the irritation test was performed by observing the skin of human objects after cream with R. communis extract was applied. The results show that R. communis leaf extract has anti-UV-B activity, With SPF value categorized as high according to the US FDA at a concentration of 1000 ppm. Furthermore, observations from 20 participants from the patch test found no skin reactions such as edema, urticaria, irritation, and erythema on any of the objects. The Ricinus communis extract has the potential to develop as a natural sunscreen for human use.
