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.

More Scientific Information

Orange 5 is a mixture consisting principally of the sodium salt of 4′,5′-dibromofluorescein and 2′,4′,5′-tribromofluorescein and 2′,4′,5′,7′-tetrabromofluorescein. 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. Orange 5 is soluble in water. Orange 5 Lake is an insoluble pigment used in applications where bleeding of the color is undesirable.
