A new study from researchers at Brigham Young University finds that alcohol-free hand sanitizer is just as effective at disinfecting surfaces from the COVID-19 virus as alcohol-based products.
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.
"Our results indicate that alcohol-free hand sanitizer works just as well, so we could, maybe even should, be using it to control COVID," said lead study author Benjamin Ogilvie.
Test Results of Germbloc Hand Sanitizers vs. Coronavirus
Germbloc Hand Sanitizer Foam and Hand Sanitizer Lotion- with the active ingredient benzalkonium chloride- were independently tested at Bio-Science Laboratories, Inc. In Bozeman, Montana against Coronavirus 29E using ASTM E1052 testing, an In-Vitro Time-Kill method. The effectiveness of the sanitizer was measured at separate intervals of 30 seconds, one minute, and three minutes. Bioscience Laboratories, INC. found both products to be 99.99% effective in killing Coronavirus 229E, a strain belonging to the same family as COVID-19.
