What it does in our products:
Benzalkonium chloride 0.1% is an antiseptic and disinfectant that helps prevent the growth of bacteria, yeast, and fungi.[2,3,4] It is often found in foaming hand sanitizers, soaps, nasal sprays, and other products.
How it's made:
Benzalkonium chloride 0.1% is a quaternary ammonium compound that can be made by methylating a primary amine from a fatty acid or a blend of fatty acids to form dimethyl alkylamine. This is then quaternized with benzyl chloride.[6,7] Benzalkonium chloride is soluble in alcohol, acetone, and water.
Why we use it:
We use benzalkonium chloride 0.1% in our hand sanitizer as an antiseptic and disinfectant. It is the sole active ingredient in the product that ensures 99.9% of bacteria and microbes are eliminated from the surface of the hands. Some studies indicate the ingredient may be an eye irritant in certain concentrations.[9,10]
