Many do have quaternary ammonium compounds, but it's important to consider the concentration as well. I've looked into a few products containing quat ammonium compounds that weren't on List N, and they all had concentrations ~10x lower than the items on List N. "The dose makes the poison" applies to pathogens just as much as it does to people!

Many of the products on the N list use quaternary ammonium compounds as their active ingredients. Although not specifically found on the N list, Dow Corning 5700 (27668-52-6) is a silane coupled quaternary ammonium compound that is used in a number of products to provide lasting antimicrobial protection. One such product is "The Tile Doctor Shield", for use on hard surfaces. The agent has also been found to bind to cotton-polyester fabric so as to resist repeated washings.
