Formulasi Gel Tabir Surya Minyak Nyamplung (Tamanu Oil) dan Uji Nilai SPF Secara In Vitro

Abstract

A Study on formulation of Tamanu oil (Calophyllum inophyllum L) as sunscreen gel and SPF value test was conducted by in vitro assay. Firstly, Tamanu oil was extracted using soxhletation and followed by identification of Tamanu oil, evaluation SPF value of Tamanu oil, formulation of sunscreen gel and determination of its SPF value using UV-Spectrophotometer The SPF result showed that SPF values of Tamanu oil in various concentration 0.2 mg/ml, 0.25 mg/ml and 0.3mg/ml were respectively 10.34± 0.06, 17.28± 0.02 and 26.07± 0.28. The results of evaluation gel sunscreen consist of 50 % of Tamanu oil, 0.5% of HPMC, 4.5% of propylenglycol, 10 % of glycerin, 0,2% of methyl paraben and aquq to 100%. The experiment result pH value, dispersive power, viscosity and viscosity change were respectively 5.5, 9.93±0.12cm,33.75±0.58dPaS and 3.95%.The SPF result showed that SPF values of sunscreen gel Tamanu oil was respectively 30.46± 0.72(after 0,6 mg/ml dilution).
