摘　　要：用十二烷基二亚丙三胺(DDT)为主要杀菌成分的洗衣液会降低洗衣液的去污性能,通过改变表面活性剂种类和添加比例,进行洗衣液去污力、稳定性和杀菌性能的研究。实验结果表明,只提高非离子表面活性剂AEO9,不会提升DDT体系洗衣液的去污效果;提高阴离子表面活性剂AES添加量,或复配AES和AEO9,可提升DDT体系洗衣液的去污效果;添加阴离子表面活性剂AOS可以有效提升DDT体系洗衣液的去污效果,且不会影响其杀菌效果与稳定性。Laundry detergents using dodecyl dipropylene triamine(DDT) as the primary antibacterial component exhibit reduced cleaning performance.This study investigated the detergency,stability,and antibacterial efficacy of DDT-based laundry detergents by varying surfactant types and blending ratios.Experimental results demonstrated that solely increasing the proportion of the nonionic surfactant AEO9 failed to enhance the cleaning efficiency of the DDT-based detergent.However,elevating the dosage of the anionic surfactant AES or combining AES with AEO9 significantly improved detergency.Additionally,increasing the anionic surfactant AOS effectively enhanced the cleaning performance of the DDT-based system without compromising its antibacterial efficacy or stability.
