Abstract

Dihydroxystearic  acid (DHSA) and octyl dihydroxystearate (DHSA-octyl ester) have been previously prepared from palm oleic acid and preliminary results showed that these compounds are suitable in personal care and cosmetics products. The objective of this research is to study the phase behavior in ternary system of DHSA/DHSA-octyl ester/RBD Palm Kernel Olein (RBDPKOo) & MCT at 85^oC. From the ternary phase diagram, results showed that all ratios of were completely in two-phase region with various concentrations of RBDPKOo and MCT. The phase changes were observed through polarizing light while the formation  of texture was confirmed  using polarizing  microscope  combination  with  heating. Needles and spherulite textures were found in this system.

 

Keywords: Dihydroxystearic Acid, octyl dihydroxystearate, RBD palm kernel olein, medium chain triglycerides,
