消毒剂氯羟二苯醚性能的试验观察

LABORATORY OBSERVATION ON PERFORMANCE OFTRICLOSAN DISINFECTANT

在悬液中，５０ｍｇ／Ｌ氯羟二苯醚对大肠杆菌与金黄色葡萄球菌作用１０ｍｉｎ，对白色念珠菌作用１５ｍｉｎ，平均杀灭率均为９９９０％。１０％小牛血清可使其杀菌效果略有下降。对不锈钢与铜无腐蚀，对铝与碳钢基本无腐蚀。低毒，对皮肤无刺激作用。

riclosan is a white crystalline powder slightly soluble in water and soluble in organic solvents Laboratory observation on its germicidal effects and corrosiveness was carried outThe results indicated that 50 mg/L triclosan solution with a 10 min contact time could kill 9990% of Escherichia coli and Staphylococcus aureus in average and the same solution with a 15 min contact time could kill 9990% of Candida albicans in average 200 mg/L triclosan solution could kill 9999% of E coli in 5 min and 9999% of E coli in suspension containing 10% calf serum in 10 min Immersion in 400 mg/L triclosan solution for 72 h at 23～27℃ did not cause corrosion of stainless steel and copper and essentially did not cause corrosion of aluminum and carbon steel The triclosan is low toxic and non-irritative to skin
