SUPPLEMENTARY INFORMATION:

I. Background

In a notice published in the Federal Register of September 1, 1995 (60 FR 45724), FDA announced that a color additive petition (CAP 5C0247) had been filed by the Ebonex Corp., P.O. Box 3247, Melvindale, MI 48122. The petition proposed to amend the color additive regulations to provide for the safe use of bone black as a color additive in cosmetics, including cosmetics intended for use in the eye area. The petitioner subsequently narrowed the proposed uses of bone black to eyeliner, eye shadow, mascara, and face powder.

During its review of the petition, the agency determined that the color additive, bone black, will require batch certification by FDA. The agency intends to give each certified batch of the subject color additive the name D&C Black No. 3. Therefore, this color additive will be identified as D&C Black No. 3.

The requested use of D&C Black No. 3 includes cosmetics for use in the area of the eye. The term “area of the eye” is defined in § 70.3(s) (21 CFR 70.3(s)) as “the area enclosed within the circumference of the supra-orbital ridge and the infra-orbital ridge, including the Start Printed Page 33665eyebrow, the skin below the eyebrow, the eyelids and the eyelashes, and conjunctival sac of the eye, the eyeball, and the soft areolar tissue that lies within the perimeter of the infra-orbital ridge.”

Section 70.5(a) (21 CFR 70.5(a)) states that “No listing or certification of a color additive shall be considered to authorize the use of any such color additive in any article intended for use in the area of the eye unless such listing or certification of such color additive specifically provides for such use.”

II. Identity and Specifications

D&C Black No. 3 is a black pigment made from calcined cattle bones. The bones are heated twice to temperatures in excess of 700°C for at least 6 hours each time. The twice burned char is then washed. The carbon content is approximately 8 percent to 10 percent and most of the remaining composition is tricalcium phosphate (as calcium hydroxyapatite).

As explained under section III.B of this document, D&C Black No. 3 may contain low levels of potentially carcinogenic polycyclic aromatic hydrocarbon (PAH) impurities. To limit the amounts of these impurities in the color additive, FDA is setting a specification for total PAHs and is requiring that D&C Black No. 3 be from a batch of bone black certified by FDA.

To limit the amounts of heavy metals in the color additive, which may be derived from the source of the color and the manufacturing process, the agency also is setting specifications for arsenic and lead. To ensure purity of the color additive, the agency also is setting specifications for carbon, calcium hydroxyapatite, moisture, and silica. To be used lawfully in cosmetics in the United States, all batches of bone black must meet the specifications identified in the regulation.

III. Safety Evaluation

A. Determination of Safety

Under section 721(b)(4) of the Federal Food, Drug, and Cosmetic Act (the act) (21 U.S.C. 379e(b)(4)), the “general safety standard” for color additives, a color additive cannot be listed for a particular use unless a fair evaluation of the data and information available to FDA establishes that the color additive is safe for that use. FDA's color additive regulations (§ 70.3(i)) define safe as “convincing evidence that establishes with reasonable certainty that no harm will result from the intended use of the color additive.”

The anticancer clause of the color additive amendments (section 721(b)(5)(B) of the act), also known as the Delaney clause) provides that for any use of a color additive which will or may result in ingestion of all or part of such additive, the color additive shall be deemed to be unsafe and shall not be listed if the additive is found to induce cancer when ingested by man or animal, or if it is found, after tests which are appropriate for the evaluation of the safety of additives for use in food, to induce cancer in man or animal (section 721(b)(5)(B)(i) of the act). Further, under section 721(b)(5)(B)(ii) of the act, for any use of a color additive which will not result in ingestion of any part of such additive, the color additive shall be deemed to be unsafe and shall not be listed if, after tests which are appropriate for the evaluation of the safety of additives for such use, or after other relevant exposure of man or animal to such additive, it is found to induce cancer in man or animal.

Importantly, however, the Delaney clause applies to the additive itself and not to impurities in the additive. That is, where an additive itself has not been shown to cause cancer, but contains a carcinogenic impurity, the additive is properly evaluated under the general safety standard using risk assessment procedures to determine whether there is a reasonable certainty that no harm will result from the intended use of the additive (Scott v. FDA, 728 F.2d 322 (6th Cir. 1984)).

B. Safety of Petitioned Use of the Additive

Because D&C Black No. 3 is made from cattle bones, one potential safety concern is the risk from using cattle materials in the preparation of bone black that could be infected with the agent that causes Bovine Spongiform Encephalopathy (BSE). To address the potential risk of BSE, FDA prohibits the use of certain cattle materials in human food and cosmetics. FDA also requires that manufacturers and processors of human food and cosmetics that are manufactured from, processed with, or otherwise contain, material from cattle establish and maintain records sufficient to demonstrate that the human food or cosmetic is not manufactured from, processed with, or does not otherwise contain, prohibited cattle materials (21 CFR 189.5 and 700.27). FDA's regulatory measures to prevent BSE contamination of U.S. food and cosmetics ensure that cattle materials that carry the highest risk of transmitting the agent that causes BSE are excluded from being used as a source to produce D&C Black No. 3 for use in cosmetics. Therefore, FDA concludes that D&C Black No. 3 prepared in compliance with these measures is safe with respect to the potential concern from using cattle materials.

Toxicity studies provided by the petitioner, including a dermal irritation study, an ocular irritation study, a delayed-contact hypersensitivity study, and a bioavailability study, demonstrate the color additive itself is safe for the proposed cosmetic uses. However, the color additive has been shown to contain several impurities in trace amounts, including carcinogenic PAHs. To minimize exposure to PAH impurities, the agency is setting a limit for total PAHs in D&C Black No. 3 of not more than 5 milligrams (mg)/kilogram (kg) (5 parts per million). As discussed in the next three paragraphs, the limit for total PAHs for D&C Black No. 3 will provide a reasonable certainty that no harm will result from the intended use of the color additive.

Current data have shown that benzo(a)pyrene (B[a]P) is one of the most potent carcinogens of the PAH family. To assess the risk from exposure to PAHs, FDA used toxic equivalency factors (TEFs) to express the comparative toxicity of individual PAHs as fractions of the toxicity of B[a]P. This approach expresses the amount of PAHs present in terms of B[a]P equivalents and estimates the risk for a mixture of PAHs as if it were comprised of one chemical compound. Under this methodology, B[a]P was assigned a TEF of 1. In estimating the exposure of B[a]P equivalents from the petitioned uses of the color additive, FDA normalized the residue levels of the individual PAHs to yield a total PAH concentration of approximately 5 mg/kg (the limit for total PAHs set by the regulation). Multiplying the normalized residue level for each PAH by the TEF for that PAH and summing the results yields a B[a]P-equivalent PAH concentration of approximately 1.2 mg/kg. Data from a bioavailability study presented in the petition show that B[a]P is not absorbed in appreciable amounts from cosmetic matrices (4 percent to 6 percent absorption) (Refs. 1 and 2). However, as a conservative assumption based on the chemical composition of the additive, the agency concluded that up to 50 percent of the total PAHs were likely to be extracted from the additive under typical use conditions, and thus available for absorption by the body (i.e., not bound to the cosmetic formulation).

The agency used data from a carcinogenesis bioassay on B[a]P (Ref. 3), to estimate the upper-bound limit of lifetime human risk from exposure to B[a]P equivalents resulting from the Start Printed Page 33666petitioned uses of the color additive. This bioassay reported treatment-related benign forestomach tumors or esophageal tumors in male rats exposed to B[a]P. Using a linear-at-low-dose extrapolation method and tumor incidence data from the bioassay, FDA estimated the carcinogenic unit risk for B[a]P to be 1.75 (mg/kg body weight/day)-1. Using this unit risk and an estimated daily exposure of 5 x 10-8 mg of B[a]P equivalents/kg body weight/day, FDA estimates the upper-bound lifetime human risk from the petitioned uses of the color additive to be 8.8 x 10-8 (Ref. 1).

Because conservative assumptions were used to estimate exposure, an individual's actual exposure to PAHs is expected to be substantially less than the estimated exposure. The agency concludes that there is reasonable certainty that no harm from exposure to PAHs would result from the petitioned use of the color additive[1] (Ref. 4).

The agency also considered the potential risk from benzaldehyde, benzonitrile, biphenyl, isoquinoline, pyridine and quinoline, which are additional impurities produced in trace amounts in the color additive from the manufacturing process. The agency concludes that none of these substances is present in the color additive at levels that raise any safety concerns, and that no specifications are necessary to control the amount of these substances as impurities in the color additive (Ref. 4).

IV. Conclusions

Based on data in the petition and other relevant considerations discussed previously, FDA concludes that there is a reasonable certainty that no harm will result from the petitioned use of D&C Black No. 3 as a color additive in eyeliner, eye shadow, mascara, and face powder. The agency also concludes that the color additive will achieve its intended technical effect, and thus, is suitable for this use. The agency further concludes that, in accordance with 21 CFR 71.20(b), batch certification of D&C Black No. 3 is necessary to protect the public health because of the need to limit the level of PAH impurities, some of which have been shown to be carcinogenic. Therefore, 21 CFR part 74 should be amended as set forth in this document.

V. Inspection of Documents

In accordance with § 71.15 (21 CFR 71.15), the petition and the documents that FDA considered and relied upon in reaching its decision to approve the petition will be made available for inspection at the Center for Food Safety and Applied Nutrition by appointment with the information contact person (see FOR FURTHER INFORMATION CONTACT). As provided in § 71.15, the agency will delete from the documents any materials that are not available for public disclosure before making the documents available for inspection.

VI. Environmental Impact

The agency has carefully considered the potential environmental effects of this action. FDA has concluded that the action will not have a significant impact on the human environment, and that an environmental impact statement is not required. The agency's finding of no significant impact and the evidence supporting that finding, contained in an environmental assessment, may be seen in the Division of Dockets Management (see ADDRESSES) between 9 a.m. and 4 p.m., Monday through Friday.

VII. Paperwork Reduction Act of 1995

This final rule contains no collection of information. Therefore, clearance by the Office of Management and Budget under the Paperwork Reduction Act of 1995 is not required.

Footnotes

1.   FDA also estimated the upper-bound lifetime risk to PAHs using the worst-case assumption that PAHs are present at the maximum allowable limit of 5 mg/kg, and that all PAHs present have carcinogenic potency equivalent to B[a]P. Based on this very conservative approach, the upper-bound limit of lifetime human risk from the petitioned uses of the additive is 3.7 x 10-7 (Ref. 1).
