A series of novel zwitterionic phosphobetaine (PPBT) surfactants were synthesized using long chain fatty alcohol, epichlorohydrin, dimethylamine and sodium dihydrogen phosphate as raw materials. The physicochemical properties of the phosphobetaine surfactants such as isoelectric point, foaming, surface tension, critical micelle concentration (CMC) and Krafft point were measured. Low CMC and surface tension values indicated the surface activities of the phosphobetaine surfactants were quite excellent. The CMC and surface tension values of PPBT/SDS mixed systems were determined. It was found both of CMC and surface tension values decreased compared with single surfactant system because of the association between dodecyl sulfate anions and cationic groups in phosphobetaine by electrostatic attraction.
