[Docket No. 93F-0132]

Indirect Food Additives: Paper and Paperboard Components

AGENCY: Food and Drug Administration, HHS.

ACTION: Final rule.

SUMMARY: The Food and Drug Administration (FDA) is amending the food additive regulations to provide for the safe use of a mixture of hydroxymethyl-5,5-dimethylhydantoin and 1,3-bis(hydroxymethyl)-5,5- dimethylhydantoin as a preservative in clay-type fillers for paper and paperboard intended for use in contact with aqueous and fatty food. This action is in response to a petition filedby Lonza, Inc.

DATES: This rule is effective March 29, 2000. Submit written objections and requests for a hearing by April 28, 2000.

ADDRESSES: Submit written objections to the Dockets Management Branch (HFA-305), Food and Drug Administration, 5630 Fishers Lane, rm. 1061, Rockville, MD 20852.

SUPPLEMENTARY INFORMATION:

1. Background

   In a notice published in the Federal Register May 17, 1993 (58 FR 28882), FDA announced that a food additive petition (FAP 3B4367) had been filedby Lonza, Inc., c/o Delta Analytical Corp., 1414 Fenwick Lane, Silver Spring, MD 20910. The petition proposed to amend the food additive regulations in Sec. 175.105 Adhesives (21 CFR 175.105), Sec. 175.300 Resinous and polymeric coatings (21 CFR 175.300), and Sec. 176.170 Components of paper and paperboard in contact with aqueous and fatty foods (21 CFR 176.170) to provide for the safe use of a mixture of hydroxymethyl-5,5-dimethylhydantoin and 1,3- bis(hydroxymethyl)-5,5-dimethylhydantoin as a preservative in adhesives, resinous and polymeric coatings and clay-type fillers for paper and paperboard in food-contact articles. Lonza, Inc., is currently represented by Lewis and Harrison, 122 C St. NW., suite 740, Washington, DC 20001. (Formerly represented by Delta Analytical Corp. whose current address is 7910 Woodmont Ave., Bethesda, MD 20814).

   When the petition was filedon May 17, 1993, the petitioner proposed to amend the food additive regulations in Secs. 175.105, 175.300, and 176.170. Subsequent to the filing of the petition, the petitioner amended the petition to limit the use of the additive to the manufacture of paper and paperboard under Sec. 176.170.

   FDA has evaluated data in the petition and other relevant material. Based on this information, the agency concludes that: (1) The proposed use of the additive, a mixture of

   [[Page 16519]]

   hydroxymethyl-5,5-dimethylhydantoin and 1,3-bis(hydroxymethyl)-5,5- dimethylhydantoin as a preservative in clay-type fillers for paper and paperboard intended to contact aqueous and fatty food is safe; (2) the additive will achieve its intended technical effect; and therefore, (3) the regulation in Sec. 176.170(a)(5) should be amended as set forth below.

   FDA's review of the petition indicates that the additive may contain trace amounts of formaldehyde as an impurity. The potential carcinogenicity of formaldehyde was reviewed by the Cancer Assessment Committee (the Committee) of FDA's Center for Food Safety and Applied Nutrition. The Committee noted that for many years, formaldehyde has been known to be a carcinogen by the inhalation route, but the Committee concluded that these inhalation studies are not appropriate for assessing the potential carcinogenicity of formaldehyde in food. The Committee's conclusion was based on the fact that the route of administration (inhalation) is not relevant to the safety of formaldehyde residues in food and the fact that tumors were observed only locally at the portal of entry (nasal turbinates). In addition, the agency has received literature reports of two-year drinking-water studies on formaldehyde: (1) A preliminary report of a carcinogenicity study purported to be positive by Soffritti et al. (1989), conducted in Bologna, Italy (Ref. 1); and (2) a negative study by Til et al. (1989), conducted in The Netherlands (Ref. 2). The Committee reviewed both studies and concluded, concerning the Soffritti study, ``* * * that data reported were unreliable and could not be used in the assessment of the oral carcinogenicity of formaldehyde'' (Ref. 3). This conclusion is based on a lack of critical detail in the study, questionable histopathological conclusions, and the use of unusual nomenclature to describe the tumors. Based on the Committee's evaluation, the agency has determined that there is no basis to conclude that formaldehyde is a carcinogen when ingested.

   A mixture of hydroxymethyl-5,5-dimethylhydantoin and 1,3- bis(hydroxymethyl)-5,5-dimethylhydantoin intended as a preservative in clay-type fillers for paper and paperboard intended in contact with aqueous and fatty foods is regulated under section 409 of the Federal Food, Drug, and Cosmetic Act (the act) (21 U.S.C. 348) as a food additive and not as a pesticide chemical under section 408 of the act (21 U.S.C. 346a). However, this intended use of a mixture of hydroxymethyl-5,5-dimethylhydantoin and 1,3-bis(hydroxymethyl)-5,5- dimethylhydantoin may nevertheless be subject to regulation as a pesticide under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). Therefore, manufacturers intending to market food-contact articles containing a mixture of hydroxymethyl-5,5-dimethylhydantoin and 1,3-bis(hydroxymethyl)-5,5-dimethylhydantoin for this intended use should contact the Environmental Protection Agency to determine whether this use requires a pesticide registration under FIFRA.

   In accordance with Sec. 171.1(h) (21 CFR 171.1(h)), 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 by appointment with the information contact person listed above. As provided in Sec. 171.1(h), the agency will delete from the documents any materials that are not available for public disclosure before making the documents available for inspection.

   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 Dockets Management Branch (address above) between 9 a.m. and 4 p.m., Monday through Friday.

   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.

2. Objections
