【 摘 要 】

The objective of this research was to obtain the best formulation E. cottonii and K. galanga for the production of sunscreen cream. The ratio of E. cottonii and K. galanga was 1:1, mixed in three versions of a cream with concentrations of 10%, 20%, and 30%. The sunscreen cream were evaluated based on the antioxidant activity, The sun Protection Factor (SPF) activity of the cream quality (viscosity, pH, homogeneity), and the microbial test. The IC50 values of the sunscreen cream were 44.59 μg/mL (for cream with 10% concentration), 31.47 μg/mL (for cream with 20% concentration), and 20.32 μg/mL (for cream with 30%). The SPF values were 8.8 (for cream with 10% concentration), 13.3 (for cream with 20% concentration), and 16.7 (for cream with 30% concentration). The viscosity values were 19,400 cps (for cream with 10% concentration), 18,000 cps (for cream with 20% concentration), and 15,600 cps (for cream with 10% concentration). The pH values of sunscreen cream were 6.52 (for cream with 10% concentration), 6.61 (for cream with 20% concentration), and 6.75 (for cream with 30% concentration). All of the sunscreen cream treatments were of a good homogeneity and absent at microbial test. The best formulation was Cream D, so that the E. cottonii and K. galanga have synergistic effects to be used as sunscreen.
