Alcohol, 60% concentration. That’s what your hand sanitizer needs to reliably kill the SARS-CoV-2 virus, according to the CDC. But new research out of BYU, published in the Journal of Hospital Infection, challenges this notion. It found that three commercial disinfectants—used in many hand sanitizers and surface wipes as alternatives to alcohol—kill the virus effectively. Most crucially, it found that a chemical known as benzalkonium chloride (BKC) reliably kills SARS-CoV-2. If the FDA and CDC embrace these findings, hand sanitizers could be cheaper, more enjoyable to use, and finally be plentiful on store shelves.
