Abstract

“Esterquat” which is basically the class of surface active quaternary ammonium compounds have general formula R N+X- .Locally available cheap raw material were used to synthesized cationic fabric softeners. Free fatty acids were derived from beef tallow and were treated with triethanolamine at 135oC. The obtained di-ester was refluxed with different mole ratios of dimethyl sulphate to obtain a viscous quaternary ammonium compound; the best mole ratio for DMS to Esterquat was 1.5:1. The synthesized Esterquats were evaluated for percentage yield (81.7%) and cationic content (35.7%). Physical and chemical properties were evaluated by various tests like feel panel test, water absorbing capacity and heat stability on different fabric substrates i.e., synthetic as well as natural. It was further characterized by IR spectra.
