The Effectiveness Test of Sunscreen Cream with Raw Material of Coconut Oil and Active Ingredients of Bay (Eugenia polyantha Wight ) Leaf Ethanol Extract and TiO₂

A research on the effectiveness test of sunscreen cream made of coconut oil as raw material and active ingredients of bay (Eugenia polyantha Wight) leaf ethanol extract and TiO₂ has been conducted. Sunscreen cream was made by emulsifying the water phase (distilled water, glycerin, methyl paraben and triethanolamine = TEA) which has been heated to 70° C and oil phase (lanoline, cetyl alcohol, stearic acid, coconut oil and prophyl paraben) which has been heated to 70° C as well and it was added an active ingredient of TiO₂. The mixture was then added the bay leaf ethanol extract and was stirred, until a homogeneous cream was formed. The resulting cream was determined its properties such as pH, viscosity, absorption of ultraviolet (UV) radiation and sun protection factor (SPF). From the SPF value calculated, then the effectiveness of sunscreen creams could be determined. The results showed that the resulting creams have a pH of 7.55-7.75, viscosity of 4000-10800 cps. If TiO₂ is added to a cream containing 0.5% bay leaf ethanol extract, the SPF value of the cream will increase. If the concentration of TiO₂ added to the cream is increased, the SPF of the cream will also increase. Cream with bay leaf ethanol extract of 0.5% and 6% TiO₂, has an SPF value of 3.101 and is included in the low protection category of sunscreens. (paper)
