Discussion Overview

The discussion revolves around the safety of BPA-free plastics, specifically Eastman Tritan copolyester, and the potential presence of estrogenic chemicals. Participants explore concerns regarding chemical exposure from various types of bottles, including glass, stainless steel, and aluminum, while debating the implications of using BPA substitutes.

Discussion Character

  • Debate/contested
  • Exploratory
  • Technical explanation

Main Points Raised

  • Some participants express confusion about whether Eastman Tritan contains bisphenol S (BPS) and what other estrogenic chemicals may be present.
  • One participant suggests that the risk of injury from broken glass may outweigh concerns about chemical exposure from plastics.
  • Another participant mentions a preference for stainless steel over plastics to avoid chemical exposure.
  • There is a reference to triphenyl phosphate as a potential chemical used in the production of Eastman Tritan.
  • One participant notes that while BPA is considered more dangerous, the safety of BPA substitutes remains uncertain and requires further research.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the safety of BPA-free plastics or the specific chemicals involved. Multiple competing views regarding the risks of different materials remain present throughout the discussion.

Contextual Notes

Limitations include the lack of definitive answers regarding the presence of specific chemicals in Eastman Tritan and the challenges in assessing the harm of various chemicals to human health and the environment.

A relative gave me a new bottle that is free of BPA.. but researching I found out it is a Eastman Tritan which the following articles claim still contain estrogenic chemicals.. I'm still confused by the following articles:

https://www.scientificamerican.com/article/bpa-free-plastic-containers-may-be-just-as-hazardous/
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3222987/

So does Eastman Tritan copolyester have bisphenol S (BPS)? If not.. what is the estrogenic chemicals present?

What bottles or plastic do you use?

Maybe the safest thing to use in gym is water jug made of glass?

I'd be a lot more worried about the risk of cutting an artery or tendon from broken glass than I would about chemical exposure from plastics.
But if I wanted to avoid plastics, I'd go with stainless steel.

I don't use any disposable plastic bottles, except for ( refundable ) pop at times, and very rarely the refillable type.
I am not too worried about myself since more "chemicals" I do acquire through life won't preserve me much more than the ones I already have.:))

Aluminum bottles are more common.

Good chance one chemical used in the process is triphenyl phosphate.

I think this is the study that Eastman sued Certichem over as to details of a study. You can make of it as you will.
Eastman won the suit by jury.

Note that some of the tests defined in the study, may or may not be something you do to your bottle.

Reason I referenced that article is that while there are such a thing as EA chemicals, defining the harm to humans ( and the environment ) is not at all that easy to determine.

As NTL2009 stated, sometimes there is risk assessment to be taken into account.
 
Well, this is seems scary, BPA-free does not mean chemical free, but yes BPA is more dangerous than other chemicals. And although the evidence is building against BPA substitutes, more research is needed to assess the effects on human health.
