Description

一种消毒洗衣液
技术领域
本发明属于日用化工技术领域，具体涉及一种消毒洗衣液。
背景技术
自从2003年爆发非典以来，人们对于自身接触的衣物的干净卫生有更高的要求，不仅要求衣物柔软无污垢，而且要求衣物表面无致病菌。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、消毒洗衣液和消毒液等，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，长期使用会造成衣物发黄、变脆。这两类消毒剂具有强氧化锌，对衣物的金属饰物有腐蚀性，很难与表面活性剂、助剂等配伍，一般单独使用，不宜用于洗衣液中。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，需要添加溶剂才能溶解，很难保证在衣物上无残留。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，一般单独使用，多用于洗手液中。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消毒洗衣液，该洗衣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消毒洗衣液，包括以下重量份的组分：十二烷基二甲基苄基溴化铵10～15份、双十八烷基二甲基氯化铵5～10份、亚乙基油酸酰胺乙二胺盐酸盐5～10份、脂肪醇聚氧乙烯醚8～15份、增稠剂0.1～0.5份、螯合剂0.1～0.5份、去离子水80～95份。
所述螯合剂为羟基乙叉二膦酸或柠檬酸钠。
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，上述消毒洗衣液还含有0.2～0.5重量份增白剂。
所述增白剂为乙二胺四乙酸钠。
本发明的消毒洗衣液的制备方法：
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溴化铵10～15份、双十八烷基二甲基氯化铵5～10份、亚乙基油酸酰胺乙二胺盐酸盐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，加入螯合剂和增白剂，全部溶解后，再调节pH至6.0～8.0，即为消毒洗衣液。
本发明采用三种阳离子表面活性剂和非离子表面活性剂进行复配，且通过独特的配比，达到协同抗菌的效果，不仅能有效杀灭革兰氏阳性菌和革兰氏阴性菌，还能杀灭真菌，杀菌效果好。

实验例
为证明本发明的抗菌洗手液的杀菌效果，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的洗衣液或中和剂混合，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的洗衣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。洗衣液和实验用菌置于20℃±1℃水浴恒温。吸取1.0ml细菌悬液注入4.0ml洗衣液中，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代替实验例的洗衣液。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衣液中的消毒成分。
4.2菌悬液定量杀菌实验结果
由上表可知，实施例1-4的洗衣液杀菌作用时间短，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。
