Analyses of palm kernel oil-based galactosides self-assemblies are important to determine their applications in pharmaceutical products. The palm kernel oil-based galactosides (GalPKO) are synthesized by adopting Fischer glycosylation method with minor modification. A birefringent fan-shaped texture was observed upon cooling using optical polarizing microscope (OPM) indicates formation of a smectic phase. The galactosides form isotropic phase completely at 137 °C. Water contact penetration showed that GalPKO does not form other lyotropic system except hydrated smectic phase. Based on its lyotropic behavior, critical aggregation concentration (CAC) is determined at value 0.11 mM indicating low solubility of the galactosides in water. Based on finding, galactoside can form a special class of liquid crystal mesophases and give a variety interesting application. © 2018, Malaysian Society of Analytical Sciences. All rights reserved.
