Hand sanitizers – demand for alcohol based hand sanitizer likely to fall as most transfers are not from formite plus other options are now being proven to work – https://scitechdaily.com/alcohol-free-hand-sanitizer-just-as-effective-against-covid-19-virus-as-alcohol-based-versions/

“The BYU scientists who conducted the study suspected that the CDC’s preference for alcohol sanitizer stemmed from as-yet limited research on what really works to disinfect SARS-CoV-2. To explore other options, they treated samples of the novel coronavirus with benzalkonium chloride, which is commonly used in alcohol-free hand sanitizers, and several other quaternary ammonium compounds regularly found in disinfectants. In most of the test cases, the compounds wiped out at least 99.9% of the virus within 15 seconds.”

““Benzalkonium chloride can be used in much lower concentrations and does not cause the familiar ‘burn’ feeling you might know from using alcohol hand sanitizer. It can make life easier for people who have to sanitize hands a lot, like healthcare workers, and maybe even increase compliance with sanitizing guidelines,” he said.”
