Color additives are subject to a strict system of approval under U.S. law [Federal Food, Drug, and Cosmetic Act
(FD&C Act), sec. 721; 21 U.S.C. 379e]. Except in the case of coal-tar hair dyes, failure to meet US color additive requirements causes a cosmetic to be adulterated [FD&C Act, sec. 601(e); 21 U.S. Code 361(e)]. Color additive violations are a common reason for detaining imported cosmetic products offered for entry into this country, according to FDA.
