Description
技术领域
本发明属于日用化工技术领域,具体涉及一种高效消毒洗手液。
背景技术
自从2003年爆发非典以来,人们对于洗手液的干净卫生有更高的要求,不仅要求手部无污垢,而且要求手部无致病菌。与之相应,杀菌消毒类洗涤产品迅速发展。消毒洗涤产品主要包括抗菌洗手液、抗菌洗手液和消毒液等,这些消毒产品的主要杀菌成分为含氯类(次氯酸钠、二氧化氯和二氯异氰脲酸钠等)、过氧类(过氧化氢水溶液、过碳酸钠、过硼酸钠等)、酚类(如对氯间二甲苯酚)、醛类(如戊二醛)、醚类(如三氯生)、季铵盐等。含氯类、过氧类消毒剂成本较低,杀菌彻底,但对皮肤刺激性大。酚类、醚类消毒剂,刺激较小,但是杀菌效果差,消毒剂用量大,成本高,水溶性不好。醛类杀菌效果好,杀菌广谱,杀菌用量小,但其有刺激气味,成本较高。传统季铵盐类表面活性剂不易降解,水溶性不好,与其他表面活性剂配伍性差,用于杀菌,由于长期大量使用,细菌已对其产生耐药性,抗菌效果不佳。而且消毒类洗涤产品主要针对大肠杆菌、金黄色葡萄球菌杀菌有效,但是对白色念珠菌无明显功效。
发明内容
本发明要解决的技术问题是提供一种高效消毒洗手液,该洗手液将多种表面活性剂进行复配,杀菌广谱,且杀菌效果好,不仅能有效杀灭大肠杆菌和金黄色葡萄球菌,还能有效杀灭白色念珠菌。
本发明提供的技术方案是提供一种高效消毒洗手液,包括以下重量份的组分:十二烷基二甲基苄基氯化铵10~15份、双癸基二甲基氯化铵5~10份、酰胺基乙氧基季铵盐5~10份、脂肪醇聚氧乙烯醚8~15份、增稠剂0.1~0.5份、保湿剂0.1~0.5份、去离子水80~95份。
所述保湿剂为丙二醇或水溶性羊毛脂。
所述增稠剂为卡波姆、羧甲基纤维素钠、黄原胶或卡拉胶。
进一步地,上述一种高效消毒洗手液还含有0.2~0.5重量份加脂剂。
所述加脂剂为甘油油酸酯。
本发明的一种高效消毒洗手液的制备方法:
1)取去离子水总量的30~40%加入到搅拌釜中,加热至70~80℃,边搅拌边先后加入十二烷基二甲基苄基氯化铵10~15份、双癸基二甲基氯化铵5~10份、酰胺基乙氧基季铵盐5~10份和脂肪醇聚氧乙烯醚8~15份,溶解后搅拌0.5~1h使之混合均匀,得到表面活性剂原液;
2)取去离子水总量30~40%加入到搅拌釜中,加热至50~60℃,边搅拌边加入增稠剂,持续搅拌至溶液均匀透明,得到增稠剂原液;
3)将表面活性剂原液和增稠剂原液混合,补足余量的去离子水,加入保湿剂和加脂剂(有就加,没有就不加),全部溶解后,再调节pH至6.0~8.0,即为高效消毒洗手液。

实验例
为证明本发明的高效消毒洗手液的杀菌效果,进行下述杀菌试验。
1、实验材料
1.1试验菌:金黄色葡萄球菌ATCC 6538、大肠杆菌8099、白色念珠菌ATCC 10231
1.2中和剂含3g/L卵磷脂、30g/L吐温、5g/L硫代硫酸钠、10g/L甘氨酸的稀释液。
1.3菌悬液的制备:将金黄色葡萄球菌、大肠杆菌和白色念珠菌和白色念珠菌近营养琼脂平板分化培养后,分别取其单个典型菌落接种于普通营养琼脂培养基斜面,在37℃下培养24h。用1000mg/L的胰蛋白胨生理盐水(TPS)洗下菌苔,充分振荡均匀并稀释配成实验菌悬液备用。
2、中和剂悬液定量鉴定实验
选用金黄色葡萄球菌和白色念珠菌作为代表,设计6组实验,将菌悬液与实施例1的洗手液或中和剂混合,作用至规定时间,取样接种培养,进行活菌计数。
3、悬液定量杀菌实验
实施例1~4以及对照实施例1的洗手液用无菌硬水配制成相应浓度。实验用菌用有机物干扰物等倍稀释,浓度为1×108~5×108cfu/ml。洗手液和实验用菌置于20℃±1℃水浴恒温。吸取1.0ml细菌悬液注入4.0ml洗手液中,迅速混匀并计时。作用至各预定时间,分别吸取0.5ml混合液加于4.5ml中和剂中,混匀。中和10min后,适当稀释,倾注平板法计数残存活菌,一式两份。同时做阳性对照,用PBS代替实验例的洗手液。计算杀灭对数值(KL)=对照组平均活菌浓度的对数值-实验组活菌浓度对数值。
4、结果
4.1中和剂鉴定实验结果
由上表可知,以第六组无菌生长,第1组无菌生长或仅少量菌生,第2组比第1组的细菌多,比第3、4、5组细菌少,因此判断,中和剂可安全中和洗手液中的消毒成分。
4.2菌悬液定量杀菌实验结果
由上表可知,实施例1-4的洗手液杀菌作用时间短,仅作用1min杀灭对数值就大于5,不仅能有效杀灭大肠杆菌和金黄色葡萄球菌,还能有效杀灭白色念珠菌,且杀菌浓度远远低于对照实施例1。
