This work reports two new classes of non-toxic heterocyclic quaternary ammonium surfactants (HQASs)synthesized by condensation of a series of fatty acids with 2-morpholinoethan-1-amine and pyridin-4-ylmethanamine, followed by quaternization with benzyl bromide. Their critical micelle concentration(CMC), Krafft temperature (Tk), emulsion stability and foaming properties were determined. The CMCvalues of HQASs ranged from 0.24 to 0.55 mM/L. In vitro antibacterial activity studies revealed that theHQASs possessing unsaturated hydrocarbon chains exhibited activity against all the tested bacteria(minimum inhibitory concentration = 31.25–500 mg/mL) whereas, those possessing saturated hydrocar-bon chains did not exhibit any activity
