Protel Novo Alcohol-Free Hand Sanitizer contains something called quaternary ammonium compounds instead of alcohol. This sanitizer can reduce microbes but are less effective than alcohol. Typically, this solution is much easier on the hands. Instead of using alcohol, which can be harsh on skin and can be flammable, an alcohol-free hand sanitizer uses a different active ingredient to kill germs. Protel Novo Alcohol-Free Hand Sanitizer is a low fire hazard and are non-damaging to surfaces. One other clear benefit is the extended protection that occurs. Alcohol-based product’s ability to kill bacteria ends once the product has dried on the skin, but benzalkonium-based products continue to provide protection well after the solution has dried.
