摘要： 在棕榈油乙氧基化物(NOE-Pn) (n=3,6,9,12和14)质量浓度为50 mg/L的条件下,通过研究其EO加合数(n)对由双癸基二甲基甲酸铵(DDAF)、双烷基(碳数8～10)二甲基氯化铵(D8-10)、聚六亚甲基双胍盐酸盐(IB)、双癸基甲基羟乙基氯化铵(DEQ)和十二烷基二甲基苄基氯化铵(1227) 5种阳离子表面活性剂复合组成的杀菌剂(阳离子复合杀菌剂,总质量浓度为140 mg/L,其中m(DDAF)∶m(D8-10)∶m(IB)∶m(DEQ)∶m(1227)=3∶2∶3∶3∶3)杀菌性能的影响,结果发现杀菌时间为20 min的条件下在n=9时(NOE-P9),对阳离子复合杀菌剂的影响最小,与脂肪醇聚氧乙烯(9)醚(AEO9)基本一致。在阳离子复合杀菌剂中引入非离子表面活性剂NOE-P9、AEO9和烷基糖苷(APG0810)以及阴-非离子表面活性剂脂肪醇聚氧乙烯(9)醚羧酸(AE9C),发现其对白色念珠菌的影响较大。在此基础上,对比了提高杀菌剂的总质量浓度至180 mg/L和延长杀菌时间至1 h的杀菌效果。结果发现浓度的提高使得杀菌性能略有增强;延长杀菌时间可以明显提升复合体系的杀菌效果,尤其是非离子表面活性剂质量浓度较低时,对金黄色葡萄球菌和大肠杆菌的杀灭对数值均大于6。

Abstract: Effect of number of EO adducted into palm oil ethoxylate (NOE-Pn) (n=3,6,9,12 or 14) with a mass concentration of 50 mg/L on bactericidal activity of the composite cationic disinfectant that consists of didecyldimethylammonium formate (DDAF),dialkyldimethylammonium chloride (carbon chain length 8-10,D8-10),poly hexamethylene bis-guanidine hydrochloride salt (IB),didecylmethylhydroxyethylammonium chloride (DEQ) and lauryldimethylbenzylammonium chloride (1227),with a composite mass ratio of DDAF/D8-10/IB/DEQ/1227 of 3/2/3/3/3 and an overall mass concentration of 140 mg/L was examined.Results show that the influence on composite cationic disinfectant caused by NOE-Pn occurs at n=9 (i.e.,NOE-P9) with a treatment time period of 20 min is at the minimum,which is basically same as that of fatty alcohol polyoxyethylene (9) ether (AEO9).Furthermore,introduction of either nonionic surfactant NOE-P9,AEO9,alkyl polyglycoside (APG0810) or anionic-nonionic surfactant fatty alcohol polyoxyethylene (9) ether carboxylic acid (AE9C) will result in significant impact on bactericidal activity of composite cationic disinfectant with respect to Candida albicans (ATCC10231).Comparison between effects of increase of mass concentration to 180 mg/L and extension of treatment time period up to 1 h was made and results show that the increase of mass concentration can slightly improve the bactericidal performance,while the extension of treatment time period can conspicuously raise the bactericidal efficacy especially for Staphylococcus aureus (ATCC6538) and Escherichia coli (ATCC8099),both the value of KL is higher than 6.
