What is it?

D&C Red No. 27 Aluminum Lake is a drug and cosmetic synthetic dye. The FDA lists it as a safe additive for drugs and cosmetics as per FDA standards. In cosmetics, it can be used externally and in general cosmetics, including lipsticks and in cosmetics close to the eye.[1]

According to the FDA, lakes are formed by reacting straight dyes (such as D&C Red No. 27) 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.[2] Its use in coloring pharmaceuticals and cosmetics may only be of quantities allowable by the FDA.
