Green 5, also referred to as D&C Green No. 5, is a synthetic color additive used in cosmetics and personal care products. Color additives are classified as straight colors, lakes, and mixtures. Green 5 is a straight color, which means it has not been mixed or chemically reacted with any other substance. Green 5 is produced from petroleum or coal tar sources.
The United States Food and Drug Administration (FDA) has reviewed the safety of Green 5 and determined that it may be safely used for coloring cosmetics and personal care products. This approval includes products intended for use on the lips and in products intended for use in the area of the eye, when it conforms to FDA specifications.
