FCN No. 147

 
Return to Listing
 
Food Contact Substance:  Ethylene phthalate polymers identified in 21 CFR 177.1630(e)(4)(i) and 177.1630(e)(4)(ii), items 2 and 3, 177.1637 and FCN numbers 4, 13, 14, 135 and 145 modified with polybutadienediol (PBD) (CAS Reg. Name: 1,3-Butadiene, homopolymer, hydroxy-terminated) (CAS Reg. No. 69102-90-5).
 
Notifier:  ColorMatrix Group Inc.
 
Manufacturer:  ColorMatrix Group Inc.
 
Intended Use:  As a component of ethylene phthalate polymers complying with 21 CFR 177.1630(e)(4)(i) and in 177.1630(e)(4)(ii), items 2 and 3, and FCN Numbers 4, 13, 14, 135 and 145, and ethylene naphthalate polymers complying with 21 CFR 177.1637.
 
Effective Date:  08/04/2001
 
Limitations/Specifications:  The level of PBD in finished articles and films manufactured from the subject modified polyesters may not exceed 0.5 weight percent. Such articles and films may be used in contact with aqueous, acidic and low-alcohol food types I, II, IV-B, VI-A, VI-B, VII-B and VIII under Conditions of Use A through H, as described in Table 2. The finished polybutadienediol modified polyesters must meet any specifications applicable to the unmodified polyester that is appropriate to its intended use. Adjuvant substances permitted for use in ethylene phthalate polymers complying with 21 CFR 177.1630, or ethylene naphthalate polymers complying with 21 CFR 177.1637 may be used in the polybutadienediol modified copolymers subject to any limitations in the regulation or notification authorizing the use of the adjuvant substance.
