Yellow 6 Lake

Yellow 6 Lake is a color additive made by combining the synthetic dye Yellow 6 (also known as Sunset Yellow FCF) with an insoluble material, typically aluminum hydroxide. This process creates a pigment that is stable and does not dissolve in water.

It is used to add a yellow-orange color to a wide variety of foods, especially those with low moisture content or where the color needs to be stable. Manufacturers add it to products like snacks, baked goods, and confectionery to enhance their visual appeal.

Yellow 6 Lake is an FDA-approved color additive for use in food. JECFA has evaluated the parent dye, Yellow 6, and set an acceptable daily intake. Some studies have suggested a link between synthetic food dyes, including Yellow 6, and hyperactivity in some children, though evidence is mixed. The FDA maintains that current evidence does not establish a causal link for the general population but notes that some children may be sensitive. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Yellow 6, for food use.
