Concentrations of Benzalkonium Chloride in antiseptic liquids (solutions) can vary greatly, typically from less than 0.1% up to 15%.
Solutions for direct topical application will normally contain between 0.1 and 0.5% active Benzalkonium Chloride. This concentration will provide both a preservative effect for the solution and also an antiseptic effect on the skin. Our Benzalkonium Chloride is widely used in these formulations.
