Disinfecting products, including those with quats are highly regulated and evaluated by the EPA and the U.S. Food and Drug Administration, as well as many international authorities such as the European Commission. For products containing quats to make it to the market, they must undergo a high level of rigorous testing in order to determine the impacts they may have on human health and the environment. Products can only be registered if data show that the intended uses (as described on the product labels) are safe when used as directed.
As with all cleaning products, quat-based disinfectant cleaners should only be used according to the directions on the label. Such products should NEVER be ingested or injected. If you are experiencing any issues due to an accidental spill on your skin, eye exposure, inhalation or ingestion, read the first aid instructions on the product label and if necessary, contact your local poison control center or 911.
