Alcohol-based Hand Sanitizer


Alcohol-based hand sanitizers contain varying amounts and types of alcohol, often between 60 percent and 95 percent and usually isopropyl alcohol, ethanol (ethyl alcohol) or n-propanol. Alcohol is known to be able to kill most germs. Not only are alcohol-based hand sanitizers found to be effective at killing many types of bacteria, including MRSA and E coli, they’re also effective against many viruses, including the influenza A virus, rhinovirus, hepatitis A virus, HIV, and Middle East respiratory syndrome coronavirus (MERS-CoV). Alcohol attacks and destroys the envelope protein that surrounds some viruses, including coronaviruses. This protein is vital for a virus’s survival and multiplication. But a hand sanitizer needs to be at least 60% alcohol in order to kill most viruses.
