目的观察一种酸性氧化电位水对细菌繁殖体及白色念珠菌的杀灭效果,观察该消毒剂的动物毒性。方法采用悬液定量法杀菌试验和动物毒性试验进行研究。结果该酸性氧化电位水(有效氯192mg/L,氧化还原电位1188mv,pH值为2.02)原液作用20s,对金黄色葡萄球菌、大肠杆菌的杀灭对数值均可达到5.0以上,对白色念珠菌的杀灭对数值可达到4.0以上。该酸性氧化电位水原液对家兔皮肤刺激反应积分值均为0,对雌、雄小白鼠经口LD50均大于5000mg/kg(体重),对家兔急性眼刺激反应评分均为0,对阴道粘膜刺激指数为0.45。结论该酸性氧化电位水对细菌繁殖体及白色念珠菌有良好的杀灭效果,属实际无毒类物质,对动物皮肤、眼和阴道黏膜无刺激性。
Objective To observe the killing effect of a kind of acid oxidation potential water on bacterial propagules and Candida albicans and observe the animal toxicity of this disinfectant. Methods Suspension quantitative disinfection test and animal toxicity test were carried out. Results The logarithmic value of the acid oxidation potential water (effective chlorine of 192mg / L, redox potential of 1188mv, pH value of 2.02) for 20s against Staphylococcus aureus and Escherichia coli reached above 5.0, Kill the logarithm can reach 4.0 above. The acidic oxidizing potential aqueous solution of rabbit skin irritation response integral value of 0, the female and male mice oral LD50 were greater than 5000mg / kg (body weight), the rabbit acute ocular response score were 0, the vagina Mucosal irritation index was 0.45. Conclusion The acidic oxidizing potential water has a good killing effect on bacterial propagules and Candida albicans, and is an actual non-toxic substance, which is non-irritating to animal skin, eyes and vaginal mucosa.
