The 1938 Federal Food, Drug, and Cosmetic Act (FFDCA) granted the Food and Drug Administration (FDA) the authority to regulate cosmetic products and their ingredients. The statutory provisions of the FFDCA that address cosmetics include adulteration and misbranding provisions. Cosmetics are arguably more self-regulated than other FDA-regulated products. The manner in which a cosmetic product could or should be regulated, however, is not always clear. FDA's guidelines have provided the cosmetic industry with considerable flexibility for product development and claims. The question remains as to whether that flexibility and the extent of government oversight of cosmetic products are still appropriate. This book provides an overview of the cosmetics industry and FDA regulation.
