What it is

FD&C Red #40, also known as Allura Red AC, is a synthetic color additive. It is a petroleum-based dye created through chemical synthesis. It is one of the most commonly used food dyes in the United States.

Why it's used

Manufacturers add FD&C Red #40 to provide a bright red color to a wide variety of foods and beverages. It is frequently found in items such as candies, cakes, snack cakes, non-alcoholic beverages, and other processed foods.

Health notes

FD&C Red #40 is an FDA-approved color additive for use in food. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Red #40. JECFA has evaluated it and set an acceptable daily intake, and EFSA has also evaluated it and set an acceptable daily intake. Some studies have suggested a link between synthetic food dyes, including Red #40, and hyperactivity in some children; however, the evidence is mixed, and regulatory bodies like the FDA state that current scientific evidence does not establish a causal link for the general population.

Allergen info

FD&C Red #40 is not a major allergen.
