What it is
Blue 1 Lake and Blue 2 Lake are synthetic color additives. They are pigments made by combining the water-soluble dyes (FD&C Blue No. 1 and FD&C Blue No. 2) with an insoluble metallic salt, typically aluminum hydroxide. This process creates a pigment that is insoluble in water.
Why it's used
These lakes are used to impart blue color to a wide range of foods, drugs, and cosmetics. Their insoluble nature makes them ideal for products with low moisture content, such as candies, icings, chewing gum, and baked goods. They are also found in some alcoholic beverages.
Health notes
Blue 1 Lake and Blue 2 Lake are approved color additives by the U.S. Food and Drug Administration (FDA) for use in food, drugs, and cosmetics. Concerns have been raised about synthetic food dyes, including Blue 1 and Blue 2, regarding their potential link to hyperactivity in some children; however, evidence from scientific reviews is mixed. The European Food Safety Authority (EFSA) has evaluated these dyes. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, which includes Blue 1 and Blue 2.
