Engkabang fat esters were synthesized from engkabang fat using an enzyme as catalyst. The main composition of the fat esters were oleyl palmitate, oleyl stearate and oleyl oleate. The percentage yield was 93.67%. Ternary phase diagrams systems containing fat esters/surfactant/water were constructed. Several regions appeared in the ternary phase diagrams such as isotropic, homogenous, liquid crystal, two-phase and three-phase regions. Increasing the hydrophilic-lipophilic balance value of the used surfactants gave a larger homogenous and isotropic region in ternary phase diagrams of engkabang fat esters/nonionic surfactant/deionized water. Isotropic and homogenous regions in the ternary phase diagram of engkabang fat esters: PEG-40 hydrogenated castor oil (2:1)/polyoxyethylene(20) sorbitan tri-oleate/deionized water, was the largest when compared to the other ternary phase diagrams. The isotropic and homogenous region can be used as a medium in formulation of cosmetics and pharmaceutical products such as creams, lotions, balms and lipsticks.

Oleylesters (OEs) are newly synthesized esters from different fatty acids of different chain length and oleyl alcohol using Novozyme 435 as catalyst. The phase behavior of these esters were determined by constructing the pseudoternaryphase diagrams of OEs/Tween 80/water at 25.0 ± 0.5°C. Compositions from the isotropic and homogeneous region were selected for characterization. The shortest OEs chain represents the most stable nanoemusions system with the smallest droplet for both isotropic and homogeneous regions. The results from simulation study showed that the shape of emulsion droplet was in spherical shape with the values of eccentricity (e) 0.11 to 0.17.
