What is the benzalkonium chloride (BAC) formula?

Benzalkonium chloride (BAC) is an active ingredient in household cleaners, hand sanitizers and many liquid soaps, including disinfectant soaps. As an antimicrobial agent, the BAC formula disrupts the functionality of many pathogens such as bacteria, viruses and fungi. Since it's highly effective at killing germs on the surface, many hand soaps and hand sanitizers use a BAC formula as one of many antimicrobial agents for their cleaning solutions.
