Safety Information

United States (U.S.)

U.S. Food and Drug Administration (FDA)

The U.S. Food and Drug Administration (FDA) has reviewed the safety of yellow 7 and yellow 7 lake and determined that these ingredients may be safely used for coloring externally applied drugs and cosmetics when it conforms to FDA specifications. Yellow 7 and yellow 7 lake are not permitted for use in products intended for use in the area of the eye or in products intended for use on the lips.

Expert Panel for Cosmetic Ingredient Safety

The Expert Panel for Cosmetic Ingredient Safety 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 Expert Panel 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.

Scientific Facts

Yellow 7 is a synthetic pigment sometimes referred to in general terms as a fluoran color. Color additives are classified as straight colors, lakes, and mixtures. Straight colors are color additives that have not been mixed or chemically reacted with any other substance. Yellow 7 is a straight color.

Lakes, such as yellow 7 lake, are pigments which consist generally of an insoluble metallic salt of a certified color additive deposited on an inert substrate.

Certifiable color additives, such as yellow 7, 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. Certifiable color additives typically are available for use as either “dyes” or “lakes.” Dyes dissolve in water and are manufactured as powders, granules, liquids or other special purpose forms. Lakes are the water insoluble form of the dye. Lakes are typically more stable than dyes and are ideal for coloring products lacking sufficient moisture to dissolve dyes. Lakes are often used to form the coating of drug tablets. Yellow 7 is principally fluorescein. In cosmetics and personal care products, yellow 7 and yellow 7 lake function as colorants.
