Why use alcohol-based hand sanitizer?
In order to be effective, hand sanitizer must contain at least 60% alcohol. Enveloped viruses contain a lipid layer, alcohol-based sanitizers’ help to inactivate viruses by breaking down the lipid layer.
Why doesn’t hand sanitizer contain more alcohol?
The presence of water in Ethanol/IPA solutions is vital for inhibiting the regrowth of pathogenic organisms. 70% has been used for many years in hospital disinfection and clinical environments. Alcohol concentrations of below 50% are not strong enough to be effective in this way. Concentrations above 90% are also ineffective due to requiring longer contact time. The presence of 30% water helps to slow the speed of evaporation which in turn helps to increase surface contact time, improving the antibacterial effectiveness.
What is the best way to practice hand hygiene?
Use soap and water when you can, washing for at least 20 seconds. When soap and water are not available, use a hand sanitizer.
How do I use hand sanitizer properly?
Wet hands thoroughly with the product, briskly rub hands together until dry. Adults should always supervise children when using hand sanitizer. Don’t rinse hand sanitizer off.
