What is it?

FDA performs regulatory review for color additives used in foods, drugs, cosmetics, and medical devices. D&C Yellow No. 10 Lake is a FDA-approved color commonly used to dye dosage forms such as tablets and capsules. D&C Yellow No. 10 Lake is approved for use in drugs and cosmetics but it is not approved as a colorant for food, as noted by the D&C notation.

FD&C colors are the colors certified for use by the U.S. FDA in the food, drug, and cosmetic industry. D&C Yellow No. 10 Lake may be safely used as a color additive when FDA specifications are followed.

According to the FDA, lakes are formed by reacting straight dyes (such as D&C Yellow No. 10) with precipitants and salts. Aluminum is often a component. Lakes may be used as color additives for tablet coatings due to their stability.[1][2]
