In an article published on August 11, 2016 by The Washington Spectator, journalist Lou Dubose reports on a new plastic baby bottle marketed as bisphenol A (BPA, CAS 80-05-7)- and phthalate-free, and generally estrogen activity (EA)-free. The bottle was developed by U.S. company ProductPure, which is a spinoff of the two companies CertiChem and PlastiPure who test plastics for EA and develop EA-free plastics. In 2013 CertiChem and PlastiPure were found guilty of making false claims about Tritan™, a BPA-free plastic resin produced by chemical company Eastman (FPF reported). CertiChem and PlastiPure researchers found that Tritan™ showed EA in in vitro cancer cell line assays. Upon publication of their results, CertiChem and PlastiPure were sued by Eastman for false advertising and conflict of interest (FPF reported).

The ProductPure bottle is made from polypropylene (PP) using a process developed in PlastiPure’s laboratory, Dubose writes. According to Mike Usey, CEO of PlastiPure, the manufacturing process turning plastics into a baby bottle is crucial because additives, catalysts, and overheating can create EA in a “clean” plastic. Samples of each production run are tested by CertiChem before the bottles are distributed to stores and shoppers.
