How Much Alcohol is Required in Hand Sanitizers to Prevent COVID Infection and Spread?

Since the COVID (SARS-CoV-2) pandemic began in earnest back in March, 2020, there has been one consistent message. To prevent the spread of COVID, it’s essential to wear a mask, social distance at 6 feet (2 meters), and wash your hands thoroughly in a lather for 20 seconds or use hand sanitizer. I remember visiting Target around that time and witnessing the frenzy of shoppers attacking the hand sanitizer shelves (just as they had the soap and toilet paper shelves) and basically depleting all inventory for weeks. And wondering when the next shipment of hand sanitizer would arrive, I also remember shoppers being told by a calm Target employee to “just wash your hands.” It is true that washing hands is effective as long as we are compliant in the process: 20 seconds, lather every part of your hands, rinse, and towel off. However, we’re not always compliant and sinks are not always available.


80% ethyl alcohol hand sanitizer is recommended by the CDC

According to the CDC (Centers for Disease Control and Prevention), the recommended Alcohol-Based Hand Rub (ABHR) is 60-95% alcohol. However, it states that the final concentration in your hand sanitizer should be at least 80% ethyl alcohol or 75% isopropyl alcohol because it is in alignment with the guidelines set forth by the World Health Organization (WHO).


Is hand washing still effective in preventing COVID?

Hand washing for 20 seconds with lathered soap is effective. However, the CDC states that ethyl alcohol- or isopropyl alcohol-based hand sanitizers are preferred over soap and water because there’s better and more effective compliance compared to washing with soap and water. In other words, people in general are less likely to wash for 20 seconds thereby increasing the risk of COVID spread. And, given the right formula, hand sanitizers can also be less irritating.
