Yellow #6 & Red #40

Yellow #6 (also known as Sunset Yellow FCF) and Red #40 (also known as Allura Red AC) are synthetic color additives derived from petroleum. They are produced through chemical synthesis.

These dyes are used to impart bright yellow-orange and red colors, respectively, to a wide range of processed foods. They are commonly found in candies, baked goods, beverages, and dessert toppings to enhance visual appeal.

Yellow #6 and Red #40 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 #6 and Red #40. Concerns have been raised about a potential link between synthetic food dyes and hyperactivity in some children, though scientific evidence on this topic is mixed. Both JECFA and EFSA have evaluated these dyes and set acceptable daily intakes.
