FD&C Yellow Lake #6

FD&C Yellow Lake #6 is a synthetic color additive derived from petroleum. It is created by adsorbing the water-soluble dye FD&C Yellow #6 onto an insoluble metallic salt, typically aluminum hydroxide. This process forms a pigment that is oil-dispersible and more stable in products containing fats or oils.

Manufacturers add FD&C Yellow Lake #6 to provide a yellow-orange color to a variety of foods. It is often used in snacks, baked goods, dairy products, and confectionery, especially in items like cheese-flavored snacks, popcorn, and candies where a stable, non-bleeding color is desired.

In the United States, FD&C Yellow Lake #6 is an FDA-approved color additive. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Yellow 6. Some studies have suggested a possible link between synthetic food colors, including Yellow 6, and hyperactivity in some children, though evidence has been mixed. JECFA has evaluated Yellow 6 and set an acceptable daily intake. EFSA has also evaluated Yellow 6.
