SUPPLEMENTARY INFORMATION:

I. Introduction

In a notice published in the Federal Register of October 6, 1997 (62 FR 52136), FDA announced that a color additive petition (CAP 7C0251) had been filed by Zauder Bros., Inc., c/o Schiff & Co., 1129 Bloomfield Ave., Start Printed Page 48376West Caldwell, NJ 07006. The petition proposed to amend the color additive regulations to provide for the safe use of zinc sulfide as a color additive in externally applied cosmetics. During its review of the petition, the agency determined that the subject color additive is zinc sulfide containing an added copper activator that produces a luminescent color. Therefore, the agency is establishing luminescent zinc sulfide as the common or usual name of the color additive.

II. Identity, Technical Effect, and Specifications

Luminescent zinc sulfide is zinc sulfide containing 0.01 weight percent (100 parts per million) copper (Ref. 1). Copper functions as an activator. Following excitation by daylight or a suitable artificial light, luminescent zinc sulfide produces a yellow-green phosphorescence with a maximum at 530 nanometers (Ref. 1). The petitioner intends to use luminescent zinc sulfide in nail polishes and facial creams to produce a “glow-in-the-dark” effect.

The luminescent zinc sulfide that is the subject of the petition contains 100± 5 parts per million copper. To ensure that the color additive in finished products contains an effective level of copper consistent with the material identified in the petition, the agency is establishing the range of copper as 100# 5 parts per million in new § 73.2995(b).

In addition to copper, other activators, for example cobalt, may also be added to zinc sulfide to obtain pigments with different phosphorescent properties (Ref. 1). However, the petitioner did not request the listing of zinc sulfide containing activators other than copper and the petition contains no relevant safety data. Therefore, phosphorescent zinc sulfide pigments containing activators other than copper are not covered by this final rule.

III. Safety Evaluation

The petitioner proposed to use luminescent zinc sulfide in nail polishes and specialized facial makeup preparations for use on limited occasions such as Halloween. The agency reviewed the data in the petition and determined that luminescent zinc sulfide is not a dermal irritant or dermal sensitizer. The agency also reviewed two skin absorption studies in the petition. The agency determined that these studies showed an apparent low skin absorption of luminescent zinc sulfide, and that the petitioned use of luminescent zinc sulfide in facial makeup preparations is safe (Ref. 2). However, the agency also determined that these absorption studies were limited in their ability to measure skin absorption under all conditions of use. Therefore, new § 73.2995(c)(2) restricts the use of facial makeup preparations containing luminescent zinc sulfide to limited occasions (e.g., Halloween). In other words, under new § 73.2995(c)(2), facial makeup preparations containing luminescent zinc sulfide are not intended for regular or daily use. Furthermore, based on the luminescent zinc sulfide concentrations in facial makeup preparations stated in the petition, new § 73.2995(c)(1) limits the amount of luminescent zinc sulfide in facial makeup preparations to 10 percent by weight of the final product. The agency notes that luminescent zinc sulfide in nail polish would be bound in the polish once it dries on the nail, and hence, the skin contact of luminescent zinc sulfide would be minimal. Therefore, the agency concludes that a limit on the amount of luminescent zinc sulfide in nail polishes is not necessary for safety reasons.

Because the agency is approving the color additive only for limited applications, new § 73.2995(c) provides clear identification of the approved uses. The agency is limiting the approved uses of luminescent zinc sulfide to specific cosmetic product categories listed in § 720.4(c) (21 CFR 720.4). These product categories were proposed by the cosmetics industry in a petition to the agency to establish an FDA-administered Voluntary Cosmetic Registration Program (VCRP). FDA adopted these product categories in 1972 with the establishment of the VCRP (37 FR 7151, April 11, 1972). The agency has determined that referencing the relevant product categories in § 720.4(c) more clearly identifies the products in which use of luminescent zinc sulfide has been approved. Section 720.4(c) includes a category for nail polish (§ 720.4(c)(8)(v), Nail polish and enamel). Although § 720.4(c) does not include a specific category for facial makeup preparations for the specialty use that was proposed in the petition, it includes a category, other makeup preparations (§ 720.4(c)(7)(ix)), which includes this use. Referencing this cosmetic product category in the regulation effectively restricts it from being used in all other categories listed under § 720.4(c)(7), for which use of the color additive was not approved. The agency finds that references to the cosmetic product categories for the approved uses, together with the specific limitations in new § 73.2995(c)(1) and (c)(2) on the use of luminescent zinc sulfide in facial makeup preparations, will effectively define the uses that the agency has reviewed and determined to be safe.

The petition does not request use of luminescent zinc sulfide in the area of the eye, and therefore, contains no data to support the use of luminescent zinc sulfide applied to the area of the eye. Therefore, the agency is not including eye area use of luminescent zinc sulfide in new § 73.2995. However, because the probable use of facial makeup preparations would include use on children's faces at Halloween, the agency is concerned about the potential for the inappropriate use of these preparations in the area of the eye. Therefore, new § 73.2995(d)(2) requires the following statement on the product label: “Do not use in the area of the eye.”

IV. Conclusion

Based on the data in the petition and other relevant material, FDA concludes that the proposed use of luminescent zinc sulfide as a color additive in nail polishes and specialized facial makeup preparations is safe, the additive will achieve its intended technical effect, and therefore, part 73 should be amended as set forth below. In addition, based upon the factors listed in 21 CFR 71.20(b), the agency concludes that certification of luminescent zinc sulfide is not necessary for the protection of the public health.

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 are available for inspection at the Center for Food Safety and Applied Nutrition (address above) by appointment with the information contact person listed above. 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 previously considered the environmental effects of this rule as announced in the notice of filing for CAP 7C0251 (62 FR 52136, October 6, 1997). No new information or comments have been received that would affect the agency's previous determination that there is no significant impact on the human environment and that an environmental impact statement is not required.
