Abstract

Faculty of Pharmacy and Science, University of Muhammadiyah Prof. Dr. Hamka, Jakarta, Indonesia Palm oil is one of the fatty oil can used as the oil phase in the microemulsion system. The purpose of this research was to identify the effect of increasing concentration of combination of surfactant and cosurfactant on the physical stability of palm oil microemulsion. This oil was formulated into microemulsion system by increas ing concentration of combination of tween 80 and sorbitol (1:1) in various concentrations, which were 54%, 56%, 58% and 60% as surfactant and cosurfactant component. The evaluation included organoleptic, viscosity test, pH, density, surface tension and particle size and zeta potential test. The pH showed in the range 5.8 to 6.4. Viscosity value obtained between 637.47 to 808.20 Cps. Density measurement were between 1.1123 to 1.1235 g/ml. The results of surface tension obtained between 39.76 to 43.07 dynes/cm. The results of particle size measurement results obtained from 21.27 to 23.97 nm and the zeta potential between −10.28 to −18.03. It can be concluded that the increasing of concentration of surfactant and cosurfactant can improve physical stability of the microemulsion.
