Description
A yellow monoazo dye discovered in 1884 by H. Ziegler. Tartrazine is used to color food, drugs, cosmetics, wool, fiber nylon, jute, leather, silk, paper, and acid dyeable fiber acrylic fibers. Because many people experience allergic reactions, the use of tartrazine as a food colorant is banned in Norway and Austria. It is still used in many other countries, including the U.S., in colas, candies, soups, jelly, and many other food products.
