0.2%新洁尔灭和5%甲酚皂消毒液灭菌效果研究

Study on sterilization effect of 0.2%benzalkonium bromide and 5%saponated cresol disinfectant

目的验证0.2%新洁尔灭和5%甲酚皂消毒液的消毒效果以及有效期。方法首先进行薄膜过滤法的方法学验证,再进行0.2%新洁尔灭和5%甲酚皂消毒液的消毒效果有效性验证,最后进行3次消毒液的有效期验证,确定消毒液的存放有效期。结果0.2%新洁尔灭和5%甲酚皂消毒液配制后5 d内的杀菌性能是有效的。结论0.2%新洁尔灭和5%甲酚皂消毒液存放5 d内均可用于物品表面的消毒杀菌。

Objective To verify the disinfection effect and validity of 0.2%benzalkonium bromide and 5%saponated cresol.Methods Firstly,the method of membrane filtration was verified,and then disinfection efficacy of 0.2%benzalkonium bromide and 5%saponated cresol were verified.Finally,the validity period of the disinfectant was verified 3 times to determine the validity period of the disinfectant.Results The germicidal properties of 0.2%benzalkonium bromide and 5%saponated cresol in 5 d were effective.Conclusion The 0.2%benzalkonium bromide and 5%saponated cresol can be used for surface disinfection and sterilization within 5 d.
