Blue #2 Lake And Red #40 Lake

Blue #2 Lake and Red #40 Lake are synthetic color additives. They are 'lakes,' which means the dye is combined with an insoluble substance, typically aluminum hydroxide, to create a pigment. This form makes the color more stable and suitable for certain food applications.

These ingredients are used to add blue and red colors to a wide range of processed foods and beverages. They help make products visually appealing and consistent in appearance, appearing in items like popcorn, baked goods, and chocolate.

Both Blue #2 Lake (FD&C Blue No. 2 Lake) and Red #40 Lake (FD&C Red No. 40 Lake) are FDA-approved color additives for use in food. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, which includes both Red 40 and Blue 2. Some studies have explored a possible link between synthetic food colors, including Red 40 and Blue 2, and hyperactivity in some children. However, the scientific evidence on this topic is mixed, and regulatory bodies generally conclude that for the general population, these colors are safe at typical intake levels. JECFA (the Joint FAO/WHO Expert Committee on Food Additives) has evaluated both Blue 2 and Red 40 and set acceptable daily intakes. EFSA (the European Food Safety Authority) has also evaluated these colors and set acceptable daily intakes.
