D&C Red No. 28 Aluminum Lake is a dye approved by the FDA for use in drugs and cosmetics according to the specifications set forth by the FDA. D&C Red No. 28 Aluminum Lake is not approved for use in foods. According to the FDA, lakes are formed by reacting straight dyes (such as D&C Red No. 28) with precipitants and salts. Aluminum is often a component. Lakes may be used as color additives for tablet coatings due to their stability, and may also be used for cosmetics such as eye shadows or lipsticks.
