摘　　要：采用新开发的带有乙氧基链的含氮阳离子表面活性剂———十二烷基二甲基羟乙基氯化铵(K3)与LAS进行复配,考察了复配体系的物化性能,如:界面张力、乳化力、润湿力、去污力以及K3对大肠肝菌、金黄色葡萄球菌的杀菌性能等。实验证明K3与阴离子表面活性剂有良好的复配性能与杀菌性能,对洗涤剂配方的改进,产品性能的提高具有指导意义。Newly developed ethoxy group chain containing cationic dodecyldimethyl hydroxyethyl ammonium chloride （ K3 ） is built with LAS. The properties such as interfacial tension, emulsifying ability, wetting power, detersive power and bactericidal properties to colibacillus and Staphylococcus aureus of the built system were investigated. The experiments show that it has good built performance and bactericidal properties between K3 and anionic surfactant. It is of great significance for improvement of detergent formulation and product properties.
