An evaluation of the residual activity of quick-drying agents (alcoholic solutions) used for hygienic hand disinfection is described. We looked for residual efficacy following hand disinfection with soap and water alone or followed by one of two alcoholic handrub lotions supplied from an automatic hand washing machine. The bacterial counts on the hands obtained before and within 2 successive hours after disinfection showed that alcoholic chlorhexidine was the most effective for 10 minutes after contamination of the hands. WELPAS (alcoholic chlorbenzarconium) followed this in its immediate effect and was better than soap and water alone. There were no significant differences after 30' or 120' between the three disinfecting methods.
本文描述了对用于手部卫生消毒的速干剂（酒精溶液）残留活性的评估。我们研究了仅用肥皂和水洗手后，或先用肥皂和水洗手再使用自动洗手器提供的两种酒精洗手液之一进行手部消毒后的残留效果。消毒前及消毒后连续2小时内手部的细菌计数表明，酒精洗必泰在手部污染后10分钟内效果最佳。WELPAS（酒精性氯苄烷铵）的即时效果次之，且优于仅用肥皂和水洗手。三种消毒方法在30分钟或120分钟后无显著差异。
