Mode of action : Hand sanitizers were created for use after washing hands or for those occasions when soap and water are not accessible. They are gels that contain alcohol in order to kill the germs present on the skin. Alcohol is the active ingredient in hand sanitizer that disrupts the coating of virus and bacteria particles. Damaging the outer cell-wall of the particle, the virus becomes inactive.
According to the World Health Organization (WHO), “an alcohol-containing preparation (liquid, gel or foam) designed for application to the hands to inactivate microorganisms and/or temporarily suppress their growth. Such preparations may contain one or more types of alcohol, other active ingredients with excipients, and humectants.”
The highest antimicrobial efficacy can be accomplished with ethanol (60% to 85%), isopropanol (60% to 80%), and n-propanol (60% to 80%). The activity is broad and quick. The combination of alcohols has a synergistic impact.
How much should be used? : To utilize hand sanitizers adequately, place a small quantity, the size of your thumbnail on the palm of your hand and rub it over your whole hand, including your nail beds. If the gel completely evaporates in less than 15 seconds, you have not used enough product.
