【摘要】 设计并配制了系列含脂肪醇聚氧乙烯醚羧酸钠（AE₉C）和双癸基羟乙基甲基氯化铵（DEQ）复配体系的抑菌去污二合一液体洗涤剂,测试了所配制液体洗涤剂的耐寒和耐热及冻融稳定性,并采用Ross-Miles泡沫仪、立式去污机及悬液定量法分别对产品的泡沫性能、去污力和抑菌性能进行了评价,优化了配方组成。结果表明:所配制的洗涤剂具有很好的稳定性;洗涤剂的泡沫性能和去污力不受水硬度的影响,当AE₉C/DEQ的质量比为7∶3时,体系的发泡力最低,当AE₉C/DEQ的质量比等于或低于2∶8时,洗涤剂去污力测试结果不合格;配方中AE₉C/DEQ的质量比为7∶3,6∶4和5∶5时,洗涤剂对金黄色葡萄球菌和大肠埃希氏菌的抑菌率均为100%。更多还原

【Abstract】 Bacteriostasis liquid detergent containing sodium fatty alcohol ether carboxylate（ AE₉C） and didecylmethylhydroxyethylammonium chloride（ DEQ） was designed and formulated.The cold resisting,heat resisting and freeze-thaw stability of the liquid detergent products were tested,and their foaming power,detergency as well as bacteriostasis efficacy was evaluated by Ross-Miles foam meter,Terg-O-Tometer and suspension quantitative method,respectively.The results showed that the liquid detergent product displays excellent stability.Its foaming power and detergency are not affected by water hardness.When the mass ratio of AE₉C to DEQ is 7 :3,foaming power of the product achieves the minimum.When the mass ratio of AE₉C to DEQ is lower than 2:8,its detergency test result is unqualified.When the mass ratio of AE₉C to DEQ is 7:3,6:4 or 5 :5,all the bacteriostasis rate of the three kinds of liquid detergent product against Staphylococcus aureus and Escherichia coli achieves 100%.更多还原
