Abstract

The aim of this research was to understand the influence of arbutin (3% w/vO) and olive oil addition and the increase of olive oil concentration (3, 5, and 7% w/w) on characteristic and SPF value of sunscreen product containing oxybenzone-and octyldimethyl PABA (3 : 7% w/w) in a carbomer 940 gel base. The characteristic test was done by observing the physical appearance, pH and spreading ability on the 2nd day after the product was made; while the measuring of SPF value was done with a spectrophotometric method. The result of the characteristic test showed that the addition of arbutin and olive oil affect the physical appearance (organoleptic and consistency) of sunscreen product as well as its spreading ability but has no effect on pH; while the significant raise in SPF value of the sunscreen formula showed that the addition of arbutin and olive oil affect the effectiveness of sunscreen product and an increase in olive oil concentration has lead to an increase in SPF value. Considering the result of this research, it's suggested to perform a further research to comprehend the in vivo effectiveness of this product on human skin.
