Esterquats were synthesized by esterification of palm fatty acids and triethanolamine (TEA) followed by quaternization with dimethyl sulfate. The optimum reaction conditions for the esterification of palm fatty acids and triethanolamine were found to be 160 °C under nitrogen. The esters obtained were subjected to quaternization with dimethyl sulfate at a 1:0.95 ratio. The maximum yield of synthesized esterquats was 53.0 ± 1% in isopropanol. Instrumental techniques, viz. IR and HPLC verified the esterification and subsequent quaternization of the ester obtained. The performances of the esterquats produced were evaluated by tests on towel fabric substrates. The synthesized esterquats exhibited good softness and rewettability (51 mm/6 min) for towel fabrics.
