Abstract

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 increasing
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.
