Bismuth Citrate is the bismuth salt of citric acid. Bismuth is a brittle metal with a pinkish hue. It occurs naturally in the Earth's crust and is about twice as abundant as gold.
The Food and Drug Administration (FDA) lists Bismuth Citrate as a color additive exempt from certification and it may be safely used for coloring hair on the scalp at concentrations not to exceed 0.5% of the final product. 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.
