Abstrak

Red shoot leaves contain flavonoid compounds that have potential as sunscreens because they can absorb ultraviolet rays, so they can be used as natural active ingredients for making sunscreen creams. The purpose of this study was to test the SPF value of red shoot leaves extract cream with a combination of sunflower oil and olive oil with 7 formulation, F1 (1 : 0) ; F2 (0 : 1) ; F3 (0.5 : 0.5) ; F4 (0.75 : 0.25) ; F5 (0.25 : 0.75) ; F6 (1 : 1) ; F7 (0 : 0). The UV-Vis Spectrophotometry method was used to determine the SPF value of the cream which refers to the Mansur equation and obtained the SPF value of the cream preparation F1 4.337; F2 3.822; F3 4.713; F4 5.090; F5 6.523; F6 5.551; and F7 5.271. The physical evaluation results of the three best formulas, namely F5, F6, and F7 in the organoleptical test of the preparation are brown, semi-solid, have a distinctive smell and meet the homogeneity requirements. After 28 days of storage, pH approximately 6.0, the adhesion of F5 1.18; F6 0.96; F7 0.56. The spreadability of F5, F6, and F7 met the parameters, namely, 5-7 cm. Viscosity with variations in concentration increased and the stability of the cream preparation was stable at room temperature storage, cycling test, centrifugation test with no phase separation. Based on the research conducted, F5 is the best formula.   Keywords: sunscreen, SPF, Syzygium myrtifolium, sunflower oil, olive oil
