Determination of SPF value in Serum Preparation of Ethyl acetat fraction ethanol extract of Roselle Petals (Hibiscus sabdarifa L.)

The ethyl acetate fraction of the ethanol extract roselle flower petals (Hibiscus sabdariffa L.) was reported to have an SPF value 13.83 ± 1.50 which higher than extract. So with value, can be used as a sunscreen. One cosmetic preparations that is currently growing rapidly serum. purpose this study formulate into serum had good physical quality variations in concentration xanthan gum and then determined. This research begins manufacture petals. Then fractionation (liquid-liquid partition) carried out using solvents different polarities, namely n-hexane acetate. Furthermore, formulated 0.3%, respectively; 0.6% 1.2% were tested for stability. next step determine by UV spectrophotometric method its calculation Mansur equation. results showed ethanolic could made gel qualities including organoleptic, viscosity, pH homogeneity. Serum formulas 1, 2 3 values F1 respectively, 6.8595 0.08 included moderate protection potential; F2 7.0089 0.17; F3 8.2251 0.32 extra potential. Variations formula affect viscosity potency sunscreen preparations..
