A water bottle made of Tritan

Tritan[1] is a transparent glass originally developed by the German Schott Zwiesel AG in 2002 together with University of Erlangen–Nuremberg.[2][3] Its name is derived from Titanoxide. In 2012, the Zwiesel Kristallglas AG introduced Tritan Protect.[3][4][5]

The Tritan copolymer offered by the Eastman Chemical Company since 2007 is a transparent glass-like plastic intended to replace polycarbonate, because of health concerns about Bisphenol A (BPA).[6][7] Tritan is a copolymer made from three monomers: dimethyl terephthalate (DMT), cyclohexanedimethanol (CHDM), and 2,2,4,4-tetramethyl-1,3-cyclobutanediol (CBDO).[8] Tritan (PCTG) is made without using any BPA.

In April 2008, Nalgene announced it would phase out production of its outdoor line of polycarbonate containers containing the chemical bisphenol A.[9] Nalgene now uses Tritan as a replacement for polycarbonate, as it does not contain BPA.[10]

Health controversy

In 2011, a neurobiologist at the University of Texas, George Bittner, published an article claiming most polymers, including Tritan, contained other materials with estrogenic activity.[11]

Eastman Chemical Company sued, and after a jury ruled in Eastman's favor, the Court barred Bittner from making claims about Tritan's oestrogenic activity.[6]

Similar products

Other manufacturers have developed similar products including the French ARC International's Kwarx since 2006,[12] the German Glaskoch (Leonardo) Teqton since 2009[13] and the South-Korean SK Chemicals' Ecozen, a glycol-modified polyethylene terephthalate (PETG) since 2010/2011.[14] Other manufacturers propose polypropylene (PP)[15] or methylstyrene (MS) as alternatives to Tritan.
