Abstract: Cationic surfactants derivatives using as softener of calico containing bisquaternary ammonium salt have been synthesized. Epichlorohydrin and N-octadecyldimethylamine have been used to synthesize cationic surfactant 2-hydroxy-1, 3-dis (chlorideoctadecyldimethylammonium) propane (HBOCP). The prepared surfactant is then analyzed using FTIR measurements and 1H-NMR spectra. The critical micelle concentration, foamability and foam stability of HBOCP are determined using standard tools of analysis. The minimum inhibitory concentration of HBOCP to Escherichia coli is found to be 75 ppm, Staphylococcus aureus is immune to bisquaternary ammonium salt cationic surfactant. HBOCP shows better softening property compared to the pristine cotton fabric. The average softness of calico increases from 96 mN to 63 mN after treating by 0.1wt% HBOCP.
