And Red 40 Lake

Red 40 Lake is a synthetic color additive. It is a 'lake' pigment, which means the water-soluble Red 40 dye (Allura Red AC) is chemically combined with an insoluble material, typically aluminum hydroxide, to make it oil-dispersible.

Manufacturers use Red 40 Lake to add a red color to a variety of foods. Because it is a lake pigment, it is stable in fats and oils and is often used in products with low moisture, such as snacks, candies, and baked goods.

Red 40 Lake is an FDA-approved color additive for use in food. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, which includes Red 40. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated Red 40 and set an acceptable daily intake; the European Food Safety Authority (EFSA) has also evaluated it. Some studies have suggested a link between synthetic food colors, including Red 40, and hyperactivity in some children, but scientific evidence on this topic is mixed. At typical intake levels, Red 40 Lake is generally considered safe.
