Triclosan [5-chloro-2-(2,4-dichlorophenoxy)phenol] is an antibacterial and antifungal agent that has been used since the early 1970s. It was first described by E. Model and J. Bindler in 1964. It is used in consumer products ranging from toothpaste to deodorants to toys. The safety and effectiveness of triclosan recently have come under scrutiny, and the US Environmental Protection Agency and Food and Drug Administration have initiated efforts to reexamine its health risks.
