?We have a unique ingredient in our sanitizer that makes it far superior to alcohol-based sanitizers. Alcohol-based sanitizers quit working after about 2 minutes when they dry. Ours lasts up to 3 to 4 hours, until the outer layer of your skin cells die. ?There is a massive amount of science behind the active ingredient we use. Our active ingredient has been commonly used as a pharmaceutical preservative and antimicrobial agent since the 1940’s.
