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 85oC. 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.

Asid dihidroksistearik (DHSA) dan oktil dihidroksistearat (DHSA-oktil ester) telah disediakan oleh penyelidik terdahulu menggunakan asid oleik kelapa sawit dan hasil awal menunjukkan sebatian ini sesuai untuk bahan kosmetik dan hias diri. Objektif penyelidikan ini adalah untuk mengkaji kelakuan fasa sistem ternari DHSA/DHSA-oktil ester/RBD Palm Kernel Olein (RBDPKOo) & MCT pada 85oC. Berdasarkan gambarajah fasa ternari, hasil menunjukkan untuk semua nisbah DHSA/DHSA-oktil ester yang digunakan, menunjukan kewujudan kawasan dua fasa pada berbagai kepekatan RBDPKOo dan MCT. Kajian perubahan fasa dilihat melalui cahaya terkutub dan pembentukan tekstur disahkan dengan mikroskop terkutub bersama pemanasan. Tekstur jarum dan sferulit telah ditemukan dalam sistem ini.
