In 2010, the Natural Resources Defense Council forced the FDA to review triclosan after suing the agency for its inaction. Because the FDA prohibited hexachlorophene, a compound similar to triclosan, Halden and others argued that the FDA should also ban triclosan. On December 17, 2013, the FDA issued a draft rule revoking the generally recognized as safe status of triclosan as an ingredient in hand wash products, citing the need for additional studies of its potential endrocrine and developmental effects; impact on bacterial resistance; and carcinogenic potential.
