Is the 400 ppm Quaternary Ammonia Sanitizer allowed?
On September 6, 2007, the US EPA issued in the Federal Register a final rule which amends 40 CFR 180.940(a) to allow the use of quaternary ammonia, di-n-alkyl (c 8-10) dimethyl ammonium chloride in end use solution concentration up to 400 ppm active quaternary ammonium compound in retail eating places. The chemical compound should be listed on the manufacturer’s label.
