Abstract

Cationic surfactant based on the acid profile of soybean gums is synthesized by the reaction with polyethylene
glycol than with chloroacetic acid followed by quaternization reaction with pyridine and the final cationic
surfactant were isolated. Soy Gums was extracted by water degumming. The Extraction process was carried out
in wadigroup / soya oil plant, and the fatty acid characterization and composition were determined using GasLiquid chromatography. The chemical structures of the synthesized surfactant were confirmed by FTIR and
1HNMR spectroscopic tool. And the surface and thermodynamic properties were determined and the tendency
towards adsorption and micellization was concluded.
