滴露消毒药水杀菌性能的实验观察

EXPERIMENTAL OBSERVATION ON BACTERICIDAL EFFICACY OF DETTOL

滴露消毒药水为含对氯间二甲苯酚（４－８ ％ ） 、表面活性剂、香料等成份的复方消毒剂。在悬液中，以其１∶４００ 稀释液对大肠杆菌、金黄色葡萄球菌作用１０ ｍｉｎ，杀灭率达９９－９ ％ 。以其１∶１００ 稀释液浸泡手２ｍｉｎ ，可使皮肤表面自然菌减少９０％ 以上。１０ ％ 小牛血清对其杀菌效果略有影响。该剂于３７ ℃贮放３ 个月，杀菌效果无明显变化。

Dettol is a compound disinfectant containing parachlorometaxylenol (4 8%), surfactant, perfume, etc. Suspension test indicated that the killing rate of both Escherichia coli exposed to its 1∶400 dilute solution for 5 min and Staphylococcus aureus exposed to the same solution for 10 min was 99 9%. Immersion of hands in its 1∶100 dilute solution for 2 min could reduce the natural bacteria on skin surface by more than 90%. 10% calf serum had slight influence on its bactericidal efficacy. Its bactericidal efficacy did not change obviously after storing at 37℃ for 3 months.
