Including Yellow 6 And Yellow 5

Yellow 5 (also known as tartrazine) and Yellow 6 (also known as Sunset Yellow FCF) are synthetic color additives. They are petroleum-based azo dyes, meaning they are created through chemical synthesis.

These dyes are used to give foods, beverages, and other products an orange-yellow color. They are commonly found in snacks, desserts, drinks, and processed foods to enhance their visual appeal.

Both Yellow 5 and Yellow 6 are approved by the FDA as color additives for use in food. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Yellow 5 and Yellow 6. Some studies have suggested a link between synthetic food dyes and hyperactivity in some children, though evidence is mixed and not all regulatory bodies agree on the significance of this link. JECFA has evaluated both Yellow 5 and Yellow 6 and set acceptable daily intakes for them. Yellow 5, in particular, has been associated with allergic reactions such as hives and asthma in a small number of sensitive individuals.
