A PILOT STUDY ON SUN PROTECTION FACTOR of ETANOL EXTRACT LOTION of PAPUAN GRAPE FRUIT (Sararanga sinuosa Hemsley.) AN OBSERVATIONAL STUDY

Papuan grapes contain phenolic compounds, namely flavonoids and tannins, which have antioxidant potential. This study aims to determine the physical quality of Papuan grape ethanol extract lotion preparation and determine the SPF (Sun Protection Factor) value of Papuan grape ethanol extract lotion preparation. Physical quality evaluation includes organoleptic test, homogeneity, pH, adhesion, spreadability, emulsion type, centrifugation test, and SPF value by UV-Vis spectrophotometric method. The absorbance of the sample was read at a wavelength of 290-320 nm with an interval of 5 nm. The results of the study obtained lotion preparations of milk chocolate color, smells typical of the base, soft and not sticky, homogeneous, pH of the base, formula I, formula II and formula III are 7.3; 7.0; 7.0, and 7.0. The stickiness and spreadability of the lotion meets the requirements, the emulsion type is M/A, the centrifugation test does not occur separation and the SPF value on the base formulation, FI (0.5%); FII (1%); and FIII (1.5%) namely, respectively base (1); weak protection category, FI (7) medium protection category, FII (9); strong protection category and FIII (10); strong protection category. All formulas obtained good physical quality and potential as sunscreens.
