复合季铵盐消毒剂杀菌效果的试验观察

EXPERIMENTAL OBSERVATION ON GERMICIDAL EFFICACY OF COMPLEX DISINFECTANT OF QUATERNARY AMMONIUM COMPOUNDS

复合季铵盐消毒剂主要成分为脂肪醇聚氧乙烯基甲基双辛基氯化铵、三月桂基氯化铵 ,季铵盐含量为 6 0 %。悬液定量杀菌试验表明 ,以其含 10 0mg/L季铵盐的溶液对大肠杆菌、金黄色葡萄球菌作用1min ,对白色念珠菌作用 5min ,杀灭率均达 99 9%。杀菌作用受有机物影响明显。该剂放置 56℃下 14d 。

The main ingredients of the complex disinfectant of quaternary ammonium compounds are lipidol polyoxyethylene methyl dioctyl ammonium chloride and trilauryl ammonium chloride The content of quaternary ammonium compounds is 6 0% Suspension quantitative germicidal test indicated that the killing rates of Escherichia coli and Staphylococcus aureus exposed to its solution containing quaternary ammonium compounds 100 mg/L for 1 min and Candida albicans [WT10.5,10.BZ]exposed to the same solution for 5 min attained 99 9% The germicidal effect was obviously influenced by organic substances The germicidal efficacy did not change obviously after storing at 56℃ for 14 days
