Today’s Video of the Day comes from the American Chemical Society’s Earth from Space series and features a look at how hand sanitizers kill germs.
The active ingredient in most hand sanitizers is alcohol, either in the form of ethanol, isopropanol, or n-propanol. The alcohol breaks down the outer coating of bacteria and viruses, which causes the germs to explode.
This inhibits their ability to infect humans, rendering the germs useless.
