Return to Listing
 
Food Contact Substance:  A copolymer of dimethyl terephthalate (CAS Reg. No. 120-61-6), 1,3-dimethyl-5-sulfo-1,3-benzenedicarboxylate, sodium salt (CAS Reg. No. 3965-55-7), and 1,6-hexanediol (CAS Reg. No. 629-11-8).
 
Notifier:  Teijin Ltd.
 
Manufacturer:  Teijin Ltd.
 
Intended Use:  The FCS will be used as a nucleating agent in (a) polyethylene terephthalate (PET) polymers complying with 21 CFR 177.1630 and (b) polyethylene terephthalate (PET) polymers complying with the specifications in 21 CFR 177.1630(f) for which there is an effective food contact notification.
 
Effective Date:  03/13/2002
 
Limitations/Specifications:  1. The copolymer will be used at levels up to 0.002 percent by weight of the PET polymer in contact with all food types under all conditions of use, including dual-ovenable applications. 2. The finished copolymer contains no more than 3 mole percent of the acid-based monomeric units derived from 1,3-dimethyl-5-sulfo-1,3-benzenedicarboxylate, sodium salt (CAS Reg. No. 3965-55-7)
