一种手消毒凝胶的杀菌效果观察

OBSERVATION ON GERMICIDAL EFFECT OF A HAND DISINFECTANT GEL

目的观察一种以三氯羟基二苯醚和乙醇为主要成分的复方消毒凝胶的杀菌效果和实际消毒效果。方法采用载体定量杀菌试验和现场消毒试验方法,对该消毒凝胶杀菌效果进行检测。结果该手消毒凝胶中三氯羟基二苯醚含量为1 100 mg/L,乙醇质量分数为45.1%。用该消毒凝胶原液浸泡作用3.0 min,对载体上的金黄色葡萄球菌、大肠杆菌、铜绿假单胞菌和白色念珠菌能达到全部杀灭,对脊髓灰质炎病毒的灭活对数值为1.20。用该消毒凝胶擦拭消毒作用3.0 min,对手部自然菌平均杀灭对数值为2.24。结论该手消毒凝胶对于细菌繁殖体和真菌均有很好的杀灭效果,能用于手的消毒。

Objective To know the germicidal and practical disinfection effect of a compound disinfection gel with triclosan and alcohol. Methods The carrier quantitative germicidal test and field disinfection test were used to detect the germicidal effect of the disinfection gel in the laboratory. Results The content of tricolan in the disinfectant was 1 100 mg/L, the content of alcohol in the disinfectant was 45.1%. The average killing rate of Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Candida albican on the carrier exposed to the disinfectant for 3.0min were all 100%. But the average inactivation logarithm value of Poliovirus was only 1.20. In field trial, the killing logarithm value of natural bacteria on the surface of hands was 2.24 after scrubbed by the disinfection gel for 3 min. Conclusion The disinfection gel has good germicidal effect on the vegetative form of bacteria and fungi. It can be used for hands disinfection.
