Food Contact Substance:  Styrene block copolymers with 1,3-butadiene, containing not less than 71 weight percent of polymer units derived from styrene, to which may be optionally added octadecyl 3,5-di-tert-butyl-4-hydroxyhydrocinnamate (CAS Reg. No. 2082-79-3) at levels not to exceed 0.25 percent by weight of the styrene block polymer.
 
Notifier:  ATOFINA Petrochemicals, Inc.
 
Manufacturer:  ATOFINA Petrochemicals, Inc.
 
Intended Use:  As articles or components of articles intended for contact with all types of food.
 
Effective Date:  07/04/2001
 
Limitations/Specifications:  The finished copolymer containing the optional adjuvant is intended for contact with all types of food under Conditions of Use E through G as described in Tables 1 and 2, respectively. The finished copolymers shall have a) a minimum number-average molecular weight (Mn) and weight-average (Mw) of 69,000 and 70,000, respectively; and b) glass transition points ranging from -98° to -20° and 86° to 122°.
