Hair Coloring Regulation Issues. In the United States the classification of color additives is complex. Under the Federal Food, Dmg and Cosmetic Act, all cosmetic colors must be the subject of an approved color additive petition to the Food and Dmg Administration there is an exception for coal-tar colorants used to color hair. Based on the composition of these colorants, FDA can require a certification on each manufactured batch of colorant to assure conformance with the approved specifications. In the early 1990s FDA has required certification only for synthetically derived coal-tar type colors. Many of the approved color additives, both certified and noncertified, are restricted ia their potential use. These restrictions can be found ia the color additive regulations ia the Code of Federal Regulations at 21 CFR 73 and 74.
