FD&C Yellow #5 And #6

FD&C Yellow #5 (Tartrazine) and FD&C Yellow #6 (Sunset Yellow FCF) are synthetic color additives. They are petroleum-based dyes created through chemical synthesis.

These dyes are used to impart yellow and orange-yellow colors to a wide range of foods and beverages. They are commonly found in snack foods, candies, baked goods, soft drinks, and desserts to enhance their visual appeal.

FD&C Yellow #5 and Yellow #6 are approved food additives by the FDA. In April 2025, FDA announced a plan to phase out petroleum-based synthetic dyes, which includes Yellow #5 and Yellow #6. JECFA has evaluated both Yellow #5 and Yellow #6 and set an acceptable daily intake for each. EFSA has also evaluated these color additives. Yellow #5 has been associated with allergic-type reactions, such as hives or asthma, in a small number of sensitive individuals. Evidence regarding a link between synthetic food dyes, including Yellow #5 and Yellow #6, and hyperactivity in some children is mixed, with some studies suggesting a connection and others finding no clear link.
