一种长效抑菌洗衣液的配方设计与性能研究

Formula design and performance study of a long-term antibacterial laundry detergent

通过对添加了不同杀菌成分洗涤剂的长效抑菌和去污效果进行测试对比,获得了一种具有长效抑菌效果的洗衣液。根据团体标准T/ZGXX0004—2022《日化产品长效抑菌效果的评价方法》,对6种洗衣液的长效抑菌效果进行了测试。试验结果表明,在本标准和设计的洗衣液体系中只有银离子和聚六亚甲基双胍盐酸盐(PHMB)具有一定的长效抑菌能力,且只有PHMB符合标准要求。通过调整PHMB的添加量(w/%),并对调整后的洗衣液的长期抑菌性能、标准去污力和稳定性进行测试,得到一种非离子体系的长效抑菌洗衣液。当PHMB的添加量为1.2%时,洗衣液具有标准要求的长期抑菌效果,且去污效果良好。当PHMB的添加量进一步增加到2.0%时,洗衣液能达到较好的长效抑菌效果,去污力明显减弱。另外,在高低温试验中,洗衣液的外观、理化指标、去污性能、长效抑菌性能均无明显变化。

A laundry detergent with long-term antibacterial effect was obtained by comparing the performance of six different bactericides in the formula.According to Group Standard T/ZGXX0004—2022“Evaluation Method for Long-term Antibacterial Effect of Daily Chemical Products”,the long-term antibacterial effects of six laundry detergents were tested.The test results showed that only silver ion and polyhexamethylene biguanide hydrochloride(PHMB)had a certain long-term antibacterial ability,and only PHMB could meet the requirements of the standard.By adjusting the amount of PHMB added,the long-term antibacterial effect,detergency and stability of the detergent were tested,and a non-ionic formula of long-term antibacterial laundry detergent was obtained.When the amount of PHMB added was 1.2%,the detergent had the long-term antibacterial performance required by the standard,and its detergency was good.When the amount of PHMB added was further increased to 2.0%,the laundry detergent could achieve good long-term antibacterial performance,and the detergency was significantly decreased but could still meet the requirements.In the high-and low-temperature tests,the appearance,physical and chemical indexes,detergency and long-term antibacterial performance had no significant change.
