2023年9月，Brandon L. Herdt及Luisa A. Ikner發表了一份搓手液有效成分（Benzalkonium Chloride和80% 酒精）對甲型（SARS-CoV-2，USA-WA1/2020分離株）和乙型（HCoV-229E）冠狀病毒的滅活動力，發現所有搓手液都能夠在15秒內對2種病毒株產生99.99%的殺菌效果，而病毒衰減速率和之前的幾個研究報告非常相似，進一步確認了Herdt等人（2021）、Chin等人（2020）、Ogilvie等人（2020）、Ijaz等人（2020）和Saknimit等人（1988）的發現，即商業BAK手部衛生配方和乙醇配方使冠狀病毒滅活。
Hand hygiene is critical to lower the potential for the spread of SARS-CoV-2 and other infectious agents by direct contact. When running water and soap are not available for hand hygiene, ethanol-based or Benzalkonium Chloride-based hand sanitizers are currently the recommended standard of care. Recently published data showed comparable in vitro effectiveness of benzalkonium chloride (BAK)-based and ethanol-based hand sanitizers. This paper found similar inactivation kinetics against human coronavirus HCoV-229E (genus Alphacoronavirus) concurrently with SARS-CoV-2, and Isolate USA-WA1/2020 (genus Betacoronavirus) as reported in previous reports by Herdt et al. (2021) , Chin et al. (2020) , Ogilvie et al. (2020) , Ijaz et al. (2020), and Saknimit et al.
