This isn't just hand sanitizer. It's better. The antimicrobial activity of CovaGuard is made from a unique and patent pending technology that incorporates Benzalkonium Chloride (BAC), which was chosen for its proven ability (over 30 years of evidence) to help prevent the spread of bacteria. Combining the effectiveness of BAC with additional proprietary ingredients and emollients, CovaGuard keeps skin soft and is effective in destroying harmful bacteria to provide antiseptic cleansing. We aren't kidding when we say, this isn't just any hand sanitizer!
