What it is

FD&C Red #40 (also known as Allura Red AC) and FD&C Yellow #5 (also known as Tartrazine) are synthetic color additives. These dyes are produced from petroleum-derived raw materials through chemical synthesis.

Why it's used

They are widely used to impart red and yellow colors, respectively, to a variety of processed foods and beverages. Common applications include candies, soft drinks, baked goods, cereals, and processed snacks, enhancing their visual appeal.

Health notes

Both Red #40 and Yellow #5 are FDA-approved color additives for use in food. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, which includes Red #40 and Yellow #5. JECFA has evaluated both Red #40 and Yellow #5 and set an acceptable daily intake. EFSA has also evaluated both dyes. Some studies suggest a link between synthetic food dyes, including Red #40 and Yellow #5, and hyperactivity in some sensitive children, though the evidence is mixed and not conclusive for the general population.
