A new Gimini cationic surfactant (BHAC) was synthesized using succinic acid, epichlorohydrin and N,N-dimethyldodecylamine as raw reactants. The reaction conditions of in the quaterisation reaction were investigated including the temperature, reaction time, and molar ratio. The surface properties, including critical micelle concentration (CMC), foamability and foam stability, were evaluated. The results showed that the minimum surface tension was 28.1 mN/m at the concentration of 1×10-3 mol/L, and the foamability and foam stability measurement are consistent with those of CMC.
