FD&C Yellow No. 5 And FD&C Yellow No.6

FD&C Yellow No. 5 (Tartrazine) and FD&C Yellow No. 6 (Sunset Yellow FCF) are synthetic food dyes made from petroleum. They are used to give foods a yellow or orange-yellow color.

These dyes are added to a wide range of processed foods and beverages to provide or enhance yellow and orange colors. Common uses include fruit drinks, sodas, ice cream, candies, baked goods, and snack foods.

FD&C Yellow No. 5 and FD&C Yellow No. 6 are FDA-approved color additives for use in food. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Yellow No. 5 and Yellow No. 6. Both JECFA and EFSA have evaluated these dyes and set acceptable daily intakes. Some studies have suggested a link between certain artificial food colors, including these, and hyperactivity in some children. The FDA concludes that for most children, there is no conclusive link between consuming these dyes and behavioral problems, but some sensitive children may experience effects. FD&C Yellow No. 5 (Tartrazine) can also cause allergic-type reactions, such as hives or asthma, in a small number of sensitive individuals, particularly those who are sensitive to aspirin.
