Triclosan is a chemical compound commonly found in consumer products to prevent and control bacterial contamination. It's often used in soaps, deodorants, shaving cream, toothpaste and mouthwash. It also can be found in clothing, bedding, socks, kitchenware, furniture and toys.

Because recent studies have suggested some harmful effects linked to triclosan — most notably that it contributes to the creation of resistant forms of bacteria — the U.S. Food and Drug Administration and the U.S. Environmental Protection Agency announced in early 2010 that they would be collaborating on their own studies of triclosan. In 2017, the FDA determined that triclosan and other chemicals are not generally recognized as safe and effective (GRAS).
