How do I learn more about the Goethe University Study
(Frankfurt, Germany) on bottled water with regard to endocrine disruptors?

This study looked at endocrine disruptor activity in mineral water packaged in glass, PET and Tetra pack. According to an independent analysis of the study conducted by the German BfR (Federal Institute for Health Risk Assessment), released on March 18, 2009:

"Samples of various different brands of mineral water showed considerable differences in the test system used. Differences with respect to the package (glass compared to PET) cannot, however, be inferred from the data. The possibility discussed by the authors that these substances originate from the plastic PET itself is rather doubtful because comparable hormonal activity was measured both in water samples from glass bottles and in water samples from PET bottles of the same mineral water brand."

Is it safe to refill a PET bottle?

September 25, 2007 – see below:

Yes.

The PET bottle itself poses no danger when refilled. PET is an inert plastic and does not leach harmful materials into its contents -- either when a beverage is stored unopened, or when bottles are refilled or frozen.

The PET container has been safely used for 20 years and has undergone rigorous testing under FDA guidelines to ensure its safety as a food and beverage container suitable for storage and reuse.

Opened bottles can harbour bacteria, however, as will mugs, glasses or any other beverage container. PET bottles are no more likely to foster bacteria than any other packaging or drink container. Ideally, all drinking containers -- including PET bottles -- should be washed with hot, soapy water and dried thoroughly prior to reuse.

Is it safe to drink beverages that have been frozen in PET bottles?

Yes.

There are no dangers inherent in the freezing of PET bottles, and absolutely no truth to the internet-circulated rumors that dioxins are leached from frozen PET bottles into bottle contents.

Dioxin is a chlorine-containing chemical that has no role or presence in the chemistry of PET plastic. Furthermore, dioxins are part of a family of chemical compounds formed only by combustion at temperatures well above 700 degrees Fahrenheit -- not at room temperature or below.

PET packaging is selected by companies because it is safe, recyclable, convenient and suitable for food and beverage. The U.S. Food and Drug Administration (FDA) has reviewed migration testing data and concluded the PET containers do not leach harmful amounts of substances into their contents under foreseeable conditions of use.

Is it safe to leave a PET bottle
in a hot car? 

View IBWA Statement on PET bottles in Hot or Cold Conditions, May 2009 (http://www.napcor.com/pdf/MythsAboutDioxin.pdf) 

Yes.

The idea that PET bottles "leach" chemicals when heated in hot cars is not based on any science, and is unsubstantiated by any credible evidence.

This allegation has been perpetuated by emails until it has become an urban legend, but it just isn't so.
 

Does PET contain Bis-phenol A?

No.

There is no connection between PET plastic and Bis-phenol A.

Bis-phenol A is not used in the production of PET material, nor is it used as a chemical building block for any of the materials used in the manufacture of PET. Bis-phenol A is used to make polycarbonate, a different plastic from PET.
 

Do I need to worry about
phthalates in PET?

No. "Phthalates" are a class of chemicals that include three subsets, each with different properties. PET or polyethylene terephthalate belongs to one of these phthalate subsets, but not the one most commonly associated with the term.

Ortho-phthalate is the phthalate subset most commonly referenced and discussed in popular literature and on internet sites; it has been the subject of some negative press. Often used to make various plastics more flexible, this type of phthalate is also called a plasticizer.

PET does not contain plasticizers or ortho-phthalates. Plasticizers are never substituted for terephthalates used in the manufacturer of PET, nor are the two ever mixed.

PET packaging is selected by companies for a wide variety of product applications because it is safe, strong, shatter-proof, and recyclable.
 

Is there a risk from antimony used to make PET?

March 24, 2006 statement on antimony from "Plastics Europe"
direct link to PDF – And see below:

Antimony is often used as a catalyst in the production of PET plastic. Catalysts speed chemical reactions and are commonly used in manufacturing to ensure that a process happens fast enough to make it commercially practical.

Antimony was chosen based on its performance against various selection criteria, including effectiveness as a catalyst; productivity; safety, few, if any, adverse effects; and an acceptable overall cost. Antimony, used in PET as the oxide of antimony, has been used and researched for decades. Metallic antimony is not used.

In the science of toxic effects (toxicology), two key factors are used to determine a hazard:

1) How dangerous is the material?, and

2) How much of the material is released?

A 1997 study showed that antimony oxide has very low toxicity. 1 The compound is relatively inert and does not participate in biological life. As for how much antimony oxide is released from PET, long-term studies indicate that it's very little. A report by the International Life Sciences Institute showed "less than five parts per billion" being released into liquid contents. 2 This is compliant with the Environmental Protection Agency's National Primary Drinking Water Standard.

Multiplied together, antimony oxide's very low toxicity combined with very low occurrence means very, very low risk. Its use in PET does not endanger workers, consumers, or the environment.
