In 1906、the Food and Drugs Act was passed by Congress、which prohibited the use of poisonous or deleterious colors in confectionery and the coloring or staining of food to conceal damage or inferiority. In 1927、responsibility of the Food and Drugs Act was transferred to FDA. Increasing government oversight、the Federal Food、Drug、and Cosmetic Act (FFDCA) was passed in 1938 and established the three following categories for colors: FD&C: colors used in foods、drugs and cosmetics、D&C: colors used in drugs and cosmetics when in contact with mucous membranes or ingested、and Ext. D&C: colors used in products applied externally.。
