Abstract
This study is related to the developing method of a transparent sunscreen cosmetic which has waterproofing property and no white turbidity when applied to skin. The transparent sunscreen is prepared by exploiting refractive index difference between oil-phase and water-phase of water-in-oil(W/O) emulsion. The sunscreen according to this study is prepared as a W/O type emulsion so that it is water-stable and water resistance. Also, the stability of W/O type emulsion is developed by adjusting the content of oil phase part and water phase part. As a result of this studying, the transparent W/O emulsion is prepared by adjusting the refractive index of oil-phase and water-phase within 0.004 and it is found that the stability of the transparent sunscreen is increasing when the water phase part is over 75% (w/w) of the W/O emulsion. Through clinical test of transparent sunscreen, the value of sun protection Factor(SPF) and Protection Factor of UVA(PFA) were determined. SPF and PFA values of transparent sunscreen were indicated $30.99{\pm}1.65$ and $3.01{\pm}0.30$.
