History and Regulation
Yellow No. 6 was first permitted for use in the United States under the Food, Drug, and Cosmetic Act. Unlike the “original seven” dyes from 1906, Yellow No. 6 was added to the approved list later as manufacturing and safety testing evolved.
It is currently approved for use in food, drugs, and cosmetics, though in the European Union, products containing this dye must carry a warning regarding potential effects on activity and attention in children.
