Effect of surfactant on the shear-induced structure and rheological properties of SAA/oil/fatty alcohol/water quaternary system

Abstract

The effect of surfactant on the rheological properties of quaternary systems consisting of surfactant, oil, fatty alcohol and water is studied to improve the stability of O/W cream. The basic ternary systems show the formation of lamella liquid crystals called ? gel. On the other hand, the quaternary systems behave lamella liquid crystals including M and D2 Phase. It is the study of the diverse rheological responses was done by a polarizing microscope, differential scanning calorimetry, small angle X-ray scattering, Rheometer and cryogenic scanning electron microscopy. When the different kinds of surfactant is added, quaternary systems show the diverse rheological responses. Several surfactants are used as emulsifier which is nonionic surfactant, anionic surfactant, cationic surfactant and surfactant mixtures.
