Safety Information

The Food and Drug Administration (FDA) has reviewed the safety of Green 8 and determined that it may be safely used for coloring externally applied cosmetics and drugs in amounts not exceeding 0.01% by weight of the finished product. It is not permitted for use in products intended for use in the eye area or in products intended for use on the lips. Cosmetic Ingredient Review (CIR) has deferred evaluation of this ingredient because the safety has been assessed by FDA. This deferral of review is according to the provisions of the CIR Procedures.

All color additives used in foods, drugs and cosmetics in the United States must be approved by FDA and listed in the Code of Federal Regulations. In some cases, FDA requires that each batch of color produced for use in regulated products can be used only if it is certified by the agency to meet strict specifications. FDA maintains a laboratory especially for this purpose and color manufacturers must pay a fee to support this activity. FDA only approves colors after extensive review of all safety data and publication of the basis for its approval in the Federal Register.

More Scientific Information

Certifiable color additives, such as Green 8, are used widely because their coloring ability is more intense than most colors derived from natural products; thus, they are often added in smaller quantities. In addition, certifiable color additives are more stable, provide better color uniformity and blend together easily to provide a wide range of hues. Certifiable color additives generally do not impart undesirable odors or flavors while color derived from foods such as beets and cranberries can produce such unintended effects. Green 8 is principally the trisodium salt of 8-hydroxy-1,3,6-pyrene-trisulfonic acid. In cosmetics and personal care products, Green 8 functions as a colorant.
