The Influence of Tween 80 in The Formulation of Nanoemulsion Virgin Coconut Oil

Abstract

Virgin coconut oil is a functional food oil that is beneficial to health. Nanoemulsion can increase the comfort of using VCO orally. This study aims to determine the effect of Tween 80 concentration on VCO nanoemulsion formulations. The concentration of Tween 80 used in Formula I, II and III is 30%, 20%, and 10%. nanoemulsion was prepared by using the water titration method. Characterizations of nanoemulsion were carried out organoleptic, Phase Separation, globular Size, Polydispersity index, and zeta potential. The results showed that Formula I and II in the form of a clear solution, while Formula III was a turbid solution. The formula I, II, and III are stable during storage. The best formula is F I because it has a globular size of 13.4 nm, the value of polydispersity index 0.265 and Zeta Potential is -1.8 mV.
