FD&C Yellow #6 & #5

FD&C Yellow #5 (Tartrazine) and FD&C Yellow #6 (Sunset Yellow FCF) are synthetic color additives. They are produced through chemical synthesis, typically derived from petroleum. These dyes are used to impart a yellow or orange color to foods.

Manufacturers add these dyes to enhance or standardize the color of various food products. They are commonly found in beverages, candies, baked goods, snacks, and desserts. Examples include popcorn, trail mixes, and fruit snacks.

In the United States, FD&C Yellow #5 and #6 are approved by the FDA as color additives for food. JECFA (the Joint FAO/WHO Expert Committee on Food Additives) has evaluated both dyes and set acceptable daily intakes. EFSA (the European Food Safety Authority) has also evaluated these color additives. Some individuals, particularly those with asthma or aspirin sensitivity, may experience allergic-type reactions to FD&C Yellow #5. Both dyes have been the subject of controversy regarding a potential link to hyperactivity in some children; the FDA has reviewed studies on this topic and states that while some evidence suggests a link in certain sensitive children, it is not conclusive for the general population. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Yellow 5 and Yellow 6, from the food supply.
