十二烷基二甲基苄基氯化铵在抗抑菌洗衣液中的应用

将十二烷基二甲基苄基氯化铵(1227)应用于洗衣液配方制备抗抑菌洗衣液,参照行业相关标准与市售抗抑菌洗衣液对比,全面考察了1227对产品感官和理化指标、去污力以及泡沫性能等的影响;重点考察了复配1227自制抗抑菌洗衣液的抗抑菌性能及其对人体皮肤的刺激性。结果表明,在去阴离子表面活性剂配方体系中,1227同其他表面活性剂的配伍性良好,产品的各项指标均能达到标准要求;复配1227自制抗抑菌洗衣液泡沫低,更易漂洗;复配1227质量分数为2%的自制抗抑菌洗衣液,其质量分数为1%的水溶液对大肠杆菌和金黄色葡萄球菌作用20 min的抗抑菌率均达到100%,具有较强的抗抑菌作用,远优于市售抗抑菌洗衣液对2菌种的抗抑菌效果,而且还具有较长时效的抗抑菌能力;复配1227质量分数为2%的自制抗抑菌洗衣液对人体皮肤无明显刺激作用。

Application of dodecyldimethylbenzylammonium chloride in bacteriostatic laundry detergent

Bacteriostatic laundry detergent was prepared with application of dodecyldimethylbenzylammonium chloride (1227) in its formulation. In accordance with relevant standards applied in Chinese detergent industry, the effect of 1227 on sensory and physiochemical quality indices, detergency and foaming performance of laundry detergent were comprehensively investigated, and antimicrobial performance as well as skin irritation of laundry detergent formulated with 1227 were emphatically examined and compared with that of market product with similar functions. Results indicated that, in systems of non-anionic surfactant formulations, the compatibility of 1227 with other surface active agents is good and all indices of the self-prepared bacteriostatic laundry detergent can meet requirements specified in Chinese relevant standards the foaming power of the self-prepared bacteriostatic laundry detergent is lower and easier to rinse than bacteriostatic laundry detergent product in market. Using aqueous solution of 1% mass fraction of self-prepared bacteriostatic laundry detergent containing 2% of 1227 the antibacterial rate for 20 min on both Escherichia coli and Staphylococcus aureus separately reaches 100%, which is much better than that of the l bacteriostatic laundry detergent product from market. The action effectiveness of the self-prepared bacteriostatic laundry detergent can be maintained for a longer time period and shows no obvious irritation effect to human skin.
