The Food and Drug Administration (FDA) has reviewed the safety of Red 27 and Red 27 Lake and determined that they may be safely used for coloring cosmetics and personal care products, as well as drugs when conforming to FDA specifications. These ingredients are approved for use in products intended for use on the lips, but are not permited for use in products intended for use in the area of the eye. According to U.S. regulations, all Red 27 and Red 27 Lake manufactured for use in products is subject to certification by the FDA. This certification process ensures that the strict chemical and identity specifications set by FDA are met. Cosmetic Ingredient Review (CIR) has deferred evaluation of these ingredients 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

Red 27 is chemically named as 2′,4′,5′,7′-tetrabromo-4,5,6,7-tetrachlorofluorescein. As a fluorescein color, it exhibits fluorescence properties which means that the absorption of light triggers the emission of light with a longer wavelength. This can have the effect of making the product appear to glow. Fluorescence is named after the mineral fluorite, composed of calcium fluoride, which often exhibits this phenomenon. Red 27 is soluble in water at neutral or alkaline pH. Red 27 lake is an insoluble pigment used in applications where bleeding of the color is undesirable.
