What it is
FD&C Yellow #6 and FD&C Red #40 are synthetic color additives used to impart orange and red hues, respectively, to foods and beverages. These dyes are manufactured from petroleum-based raw materials through chemical synthesis.
Why it's used
Manufacturers add these dyes primarily to enhance the visual appeal and color consistency of food products. They are commonly found in a wide range of processed foods, including soft drinks, candies, baked goods, cereals, and snack foods.
Health notes
Both FD&C Yellow #6 and FD&C Red #40 are approved by the FDA as food additives in the United States. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, which includes Red 40 and Yellow 6. Some studies have explored a possible link between synthetic food dyes, including Yellow #6 and Red #40, and hyperactivity in some children, though the evidence is mixed and regulatory bodies continue to review the research. JECFA has evaluated both dyes and set an acceptable daily intake (ADI) for each. EFSA has also evaluated these dyes and set ADIs.
