This Food Additives Status List, formerly called Appendix A of the Investigations Operations Manual (IOM), organizes additives found in many parts of 21 CFR into one alphabetized list. Additives included are those specified in the regulations promulgated under the FD&C Act, under Sections 401 (Food Standards), and 409 (Food Additives). The Food Additives Status List includes short notations on use limitations for each additive. For complete information on its use limitations, refer to the specific regulation for each substance. New regulations and revisions are published in current issues of the Federal Register as promulgated. Also refer to the Food Ingredient and Packaging inventories in the Foods section of the FDA web site to review several FDA databases of additive categories. For example, the EAFUS list (Everything Added to Food in the United States), is a helpful reference within the limitations described at the beginning of the database.
In 2010, the Natural Resources Defense Council forced the FDA to review triclosan after suing them for their 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.
