bis(2-hydroxyethyl) terephthalate - 959-26-2

Key Functions: Plasticizers & Polymer

bis(2-Hydroxyethyl) terephthalate is formed during the synthesis of polyethylene terephthalate (PET) plastics (HSDB 2003). It is generated via esterification of terephthalic acid and is subsequently polymerized via a transesterification reaction to form PET. Antimony oxide is used to catalyze the transesterification reaction. ToxServices assessed bis(2-hydroxyethyl) terephthalate against GreenScreen® Version 1.2 (CPA 2013) following procedures outlined in ToxServices’ SOP 1.37 (GreenScreen Hazard Assessment)(ToxServices 2013)
