Artificial Color Red 40

Red 40, also known as Allura Red AC, is a synthetic dye manufactured from petroleum. It is one of the most commonly used artificial food colors.

Manufacturers add Red 40 to give foods a red or orange-red color. It is widely used in candies, beverages, baked goods, dairy products, and processed snacks to enhance visual appeal.

In the United States, Red 40 is an FDA-approved color additive, meaning it has been evaluated for safety and listed for use in food. JECFA has evaluated Red 40 and set an acceptable daily intake. EFSA has also evaluated Red 40 and established an acceptable daily intake. There has been public concern and some scientific research suggesting a link between certain artificial food colors, including Red 40, and hyperactivity in some children. The FDA reviewed the available scientific evidence and concluded that while a causal link has not been established for the general population, some children with ADHD or other behavioral disorders may be sensitive to these colors. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Red 40, from food products.
