EKSTRAK ETANOL DAUN SUJI (Pleomele angustifolia) TERENKAPSULASI NANOPARTIKEL KITOSAN DALAM SEDIAAN KRIM TABIR SURYA DENGAN VARIASI TWEEN 80-SETIL ALKOHOL

ABSTRACTAntioxidants in the ethanolic extract of suji leaves (Pleomele angustifolia) have potential as a sunscreen. The use chitosan nanoparticle system is able to protect degradation flavonoids due influence temperature and light. Tween 80 cetyl alcohol play strategic role formation cream preparations. purpose this study was determine characteristics sunscreen with variations 80-cetyl containing active ingredient ethanol encapsulated system. Chitosan nanoparticles leaf (KEEDS) were prepared using ultrasonic agitation. KEEDS made into preparations (T80:SA) FI (3:3)%, FII (3:10)%, FIII (10:10)%. formed observed for organoleptic, homogeneity, type cream, measured value pH, spreadability, adhesion, viscosity, activity UV-Vis Spectrophotometer at wavelength 290–320 nm. Organoleptic data, pH analyzed descriptively, while viscosity ANOVA 95% confidence limit. visually looks homogeneous, brownish white color, soft texture, aroma leaves. preparation 4.74-4.88, O/W. variation T80:SA combination resulted significant differences values dispersion, between three formulas (sig < 0.05).Keywords: alcohol, chitosan, Suji angustifolia), sunscreen,
