聚乙二醇碘消毒性能的试验观察

聚乙二醇碘由碘与聚乙二醇络合而成,为了解其杀菌效果及其相关性能,采用悬液定量杀菌试验和理化分析方法进行了实验室观察。结果,以含有效碘500 mg/L的聚乙二醇碘消毒液,对悬液内大肠杆菌、金黄色葡萄球菌和铜绿假单胞菌作用1 m in,杀灭对数值均>5.00;对白色念珠菌作用2 m in,杀灭对数值均>5.00。用含有效碘3350 mg/L的该消毒液擦拭消毒作用1 m in,对皮肤表面和手上自然菌的杀灭对数值均>1.00。该消毒剂原液,经37℃恒温存放90 d,有效碘含量下降率平均为9.25%。结论,聚乙二醇碘消毒液对细菌繁殖体和真菌杀灭效果较好,性能稳定。

EXPERIMENTAL OBSERVATION ON DISINFECTION PROPERTY OF POLYGLYCOL IODINE

Polyglycol iodine was prepared by complexation of iodine and polyglycol.In order to know its germicidal efficacy and its related properties,suspension quantitative germicidal test and physicochemical analytic method were used to carry out laboratory observation.Results: The killing logarithm values of Escherichia coli,Staphylococcus aureus and Pseudomonas aeroginosa in suspension exposed to polyglycol iodine disinfection solution containing available iodine 500 mg/L for 1 min were >5.00 and the killing logarithm value of Candida albicans exposed for 2 min was >5.00.Wiping disinfection with the disinfection solution containing available iodine 3350 mg/L for 1 min killed the natural bacteria on skin surface and hands by a logarithm >1.00.The available iodine content of the stock solution of the disinfectant decreased by 9.25% in average after storing at 37℃ for 90 days.Conclusion: Polyglycol iodine disinfectant solution has good efficacy in killing vegetative forms of bacteria and fungi and is stable.
