Colors Fd-&-c-red #40

FD&C Red #40, also known as Allura Red AC, is a synthetic color additive. It is a petroleum-derived azo dye, meaning it is chemically synthesized from crude oil components.

Manufacturers add FD&C Red #40 to foods to give them a red color. It is commonly found in candies, beverages, baked goods, desserts, and cereals to enhance visual appeal.

In the US, FD&C Red #40 is an FDA-approved color additive for food, drugs, and cosmetics. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Red #40. JECFA has evaluated Red #40 and set an acceptable daily intake. EFSA has also evaluated this additive. There has been mixed evidence regarding a possible link between synthetic food colors, including Red #40, and hyperactivity in some children. While some studies suggest a link, others have not found consistent evidence, and the scientific community continues to review the data.
