Artificial Colors: FD&C Red No. 40 And FD&C Blue No.2

FD&C Red No. 40 and FD&C Blue No. 2 are synthetic color additives used in food. They are chemically manufactured from petroleum-based raw materials. These dyes are produced to be highly pure and consistent in color.

Manufacturers add these artificial colors to enhance the visual appeal of foods and beverages, making them more attractive to consumers. They are commonly found in a wide range of processed foods, including candies, chewing gum, baked goods, soft drinks, and cereals.

FD&C Red No. 40 and FD&C Blue No. 2 are approved by the FDA as color additives for use in food. JECFA has evaluated both of these dyes and set an acceptable daily intake for each. EFSA has also evaluated them. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Red 40 and Blue 2. Some studies have explored a potential link between synthetic food dyes and hyperactivity in some children, but the evidence is mixed, and the FDA states that available evidence does not support a causal link between exposure to colors and behavioral effects in the general population of children.
