Eastman Tritan™ copolyester is a tough, BPA-free plastic used to make various products that you use every day. Products made from Tritan are impact and shatter resistant. Plus, they stay clear and durable even after years of repeated use and dishwasher cycles.

Yes, Tritan™ is safe for you and your family. It has been rigorously tested by third-party labs to ensure its safety. It is completely free of bisphenol A (BPA), bisphenol S and any other bisphenol compounds as well as estrogenic and androgenic activity. But not only is Tritan chemically safe, it’s shatter-resistant too, so the only thing you have to worry about when someone knocks over a product made with Tritan is cleaning up spills. 

Bisphenol A (BPA) is a monomer used in some plastics, including polycarbonate. BPA also is used in the interior coatings of metal cans that hold food to prevent deterioration of the metal surface. 

Tritan is not manufactured with BPS or any other bisphenol compound that would be chemical analogs of BPA. there is no reason to expect that these substances would be present in the material.

BPA is not and has never been an ingredient or byproduct of the production of Tritan™. Validation that Tritan is a BPA-free plastic is supported by robust testing and independent third-party testing by accredited laboratories. To learn more about the testing of Tritan, visit www.tritansafe.com.

Estrogen and testosterone are hormones that are essential to many important biological processes in animals and humans, including sexual differentiation and development. Studies have suggested that certain synthetic and naturally occurring chemicals can interfere with these biological processes and lead to adverse effects.     

Endocrine disruptors are defined as chemicals that can interfere with the human endocrine system and ultimately lead to adverse health effects. Among endocrine disruptors, chemicals that mimic estrogen and testosterone in living animals are said to exhibit estrogenic activity, also known as EA, and androgenic activity, frequently known as AA.

Independent third-party labs using well-recognized scientific methods have demonstrated that Tritan plastic is free of estrogenic activity and androgenic activity.

No; nor is it a measure of the safety of a product. The number, usually located in the center of the triangular recycle symbol, is called the “resin identification code” and is intended to facilitate sorting of materials for recycling. Currently, resin identification code “7” is for “other” resins that are not defined by codes 1 through 6. Thus, a number of unrelated plastics can carry a code 7, including Tritan, polycarbonate, nylon and even the newer bio-plastics. Many well-known manufacturers identify their products made from Tritan with code 7.

Accredited universities and independent third-party labs used well-recognized scientific methods to test the plastic resin for potential estrogenic activity and androgenic activity. This battery of tests included:

Quantitative structure activity relationships (QSAR). Computer modeling of monomers to assess each substance's molecular structure and its ability to bind to human estrogen and androgen (testosterone) receptors in a manner that could lead to their activation.

Receptor transactivation assays. The estrogenic activity and androgenic activity of both the monomers and concentrated extracts of Tritan also were evaluated in vitro using both yeast and mammalian cell assays performed by two separate labs. These tests evaluate a substance's ability to bind to a hormone receptor and, induce gene expression. Extracts were generated using U.S. Food and Drug administration and European Union (EU) (specifically, Commission Regulation No. 10/2011) recommendations for food contact migration testing. Additional extracts were derived following a dishwasher simulation environment (10 days, 70ºC in Cascade® solution).

Competitive binding assays. Despite the fact that neither the QSAR nor transactivation studies showed any evidence of binding or gene expression by estrogenic or androgenic pathways, a second tier of tests based on competitive binding assays was conducted. These tests can confirm a substance's ability to specifically bind to a specific hormone receptor and can be used to calculate the relative binding affinity.

Uterotrophic assay.  This in vivo test is considered more definitive for assessing a substance's potential to elicit estrogenic responses in living biological systems. This test is also part of the Tier I Endocrine Disruption Screening Program of the U.S. Environmental Protection Agency.

Hershberger assay. This in vivo test is considered more definitive for assessing a substance's potential to elicit androgenic responses in living biological systems. This test is also part of the Tier I Endocrine Disruption Screening Program of the U.S. Environmental Protection Agency.

No, Tritan is shatter resistant, so while it has the looks and clarity of glass, it won’t break when you drop it or toss it in the bottom of your backpack. It can take all the bumps and drops of daily life and even survive some of the not-so-typical stresses.

Hundreds of dishwasher cycles, several hiking trips and even a few really long falls. Tritan™ outlasts glass, plastics and just about every other material, proven through third-party testing.
