FD&C Yellow #5 & Yellow #6

FD&C Yellow #5 (also known as Tartrazine) and FD&C Yellow #6 (also known as Sunset Yellow FCF) are synthetic color additives. They are produced from petroleum. These dyes are used to give foods a yellow or orange color.

These colorants are added to a wide range of processed foods and beverages to enhance their visual appeal. They are commonly found in snacks, candies, baked goods, soft drinks, and cereals.

The FDA has approved FD&C Yellow #5 and Yellow #6 as food additives. Concerns have been raised about a possible link between synthetic food dyes, including Yellow #5 and Yellow #6, and hyperactivity in some children. The FDA has reviewed the available scientific evidence and concluded that there is no clear evidence that these dyes cause hyperactivity in the general population, though some children may be sensitive. JECFA has evaluated both Yellow #5 and Yellow #6 and set acceptable daily intakes. EFSA has also evaluated these dyes and set acceptable daily intakes. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, which includes Yellow #5 and Yellow #6.
