FCN No. 14

Return to Listing
Food Contact Substance:  Dimethyl-2, 6-naphthalene dicarboxylate or 2,6-naphthalene dicarboxylic acid
Notifier:  BP Amoco Chemicals
Manufacturer:  BP Amoco Chemicals
Intended Use:  As a chemically-bound component of poly(oxy-1,2-ethanediyloxy carbonyl-2,6-naphthalenediyl carbonyl) homopolymer and copolymers with ethylene terephthalate
Effective Date:  03/23/2000
Limitations/Specifications:  The finished copolymers may contain up to 50 weight percent of the polymer units derived from ethylene terephthalate. The finished homopolymer and copolymers must meet any applicable specifications in 21 CFR 177.1630 appropriate to their intended use. The finished homopolymer is prepared by condensation of dimethyl 2,6-naphthalenedicarboxylate or 2,6-naphthalenedicarboxylic acid with ethylene glycol. The finished copolymers are prepared by the condensation of dimethyl-2,6-naphthalenedicarboxylate or 2,6-naphthalenedicarboxylic acid and dimethyl terephthalate or terephthalic acid with ethylene glycol. The finished homopolymer and copolymers are used as components of the base sheet or base polymer for manufacturing articles and films in contact with all food types under Conditions of Use A through H as described in Table 2. Adjuvant substances permitted for use in polymers complying with 21 CFR 177.1630 may be used in the subject polymers subject to any limitations in the authorizing regulation or notification. Manufacturers of the polymers may market the finished polymers in accord with section 409(a)(3)(B) of the Federal Food, Drug, and Cosmetic Act, provided the intended use is in conformity with this notification.
