Both the cosmetic industry and the Food and Drug Administration (FDA) have had a long and interesting history. FDA’s history began in 1906 with the enactment of the Pure Food and Drug Act. This was the first attempt to regulate the safety of products (or additives). For almost 100 years Congress has set the standards and published them in the United States Code (USC). FDA and other federal agencies promulgate regulations through notice and comment rulemaking. Proposed regulations are published in the Federal Register (FR) and the public is given an opportunity to comment. The agencies then publish in the Federal Register final regulations together with a preamble discussing each comment. Industry and regulatory scientists eagerly follow these changes and access them on the Web. Final regulations are compiled in the Code of Federal Regulations (CFR).
