Myths about PET vs Glass Bottles

Posted by


Should Supplements be Packaged in Glass Bottles or Plastic?

Many other companies have made it a mission to stress how important it is to use Glass Bottles, often pointing out the harmful chemical agent's plastic containers and twisting the facts to appear "informative".

Some of the disinformation provided is:

1. Freezing or reusing PET bottles releases unsafe levels of carcinogens such as “dioxins” or the plastics additive DEHA (diethylhydroxylamine) into whatever liquids they may contain.

2. However, such claims are inaccurate on two counts: DEHA is not used in the manufacture of PET bottles (nor is it created through the breakdown of such bottles), and DEHA is not classified as a human carcinogen:

Snopes (http://www.snopes.com/medical/toxins/plasticbottles.asp) Found that:

"...DEHA is neither regulated nor classified as a human carcinogen by the U.S. Occupational Safety & Health Administration, the National Toxicology Program or the International Agency for Research on Cancer, the leading authorities on carcinogenic substances.

In 1991, on the basis of very limited data, the U.S. Environmental Protection Agency classified DEHA as a “possible human carcinogen.” However, in 1995, EPA again evaluated the science and concluded that ” … overall, the evidence is too limited to establish that DEHA is likely to cause cancer.”

Further, DEHA is not inherent in PET as a raw material, byproduct or decomposition product.

Moreover, DEHA has been cleared by FDA for food-contact applications and would not pose a health risk even if it were present.

Finally, in June 2003, the Swiss Federal Laboratories for Materials Testing and Research conducted a scientific study of migration in new and reused plastic water bottles from three countries. The Swiss study did not find DEHA at concentrations significantly above the background levels detected in distilled water, indicating DEHA was unlikely to have migrated from the bottles. The study concluded that the levels of DEHA were distinctly below the World Health Organization guidelines for safe drinking water.

The American Cancer Society also debunked such claims, stating:

In fact, DEHA is not inherent in the plastic used to make these bottles, and even if it was the U.S. Environmental Protection Agency (EPA) says DEHA “cannot reasonably be anticipated to cause cancer, teratogenic effects, immunotoxicity, neurotoxicity, gene mutations, liver, kidney, reproductive, or developmental toxicity or other serious or irreversible chronic health effects.” Meanwhile, the International Agency for Research on Cancer (IARC), says diethylhexyl adipate “is not classifiable as to its carcinogenicity to humans.”

As for the notion that freezing water in plastic bottles releases dioxin, the American Chemical Council asserted:

There simply is no scientific basis to support the claim that PET bottles will release dioxin when frozen. Dioxins are a family of chemical compounds that are produced by combustion at extremely high temperatures. They can only be formed at temperatures well above 700 degrees Fahrenheit; they cannot be formed at room temperature or in freezing temperatures. Moreover, there is no reasonable scientific basis for expecting dioxins to be present in plastic food or beverage containers in the first place.

Johns Hopkins researcher Dr. Rolf Halden also said of such claims that:

Q: What do you make of this recent email warning that claims dioxins can be released by freezing water in plastic bottles?

A: This is an urban legend. There are no dioxins in plastics. In addition, freezing actually works against the release of chemicals. Chemicals do not diffuse as readily in cold temperatures, which would limit chemical release if there were dioxins in plastic, and we don’t think there are..."

Not All Plastics Are Safe:

Plastic bottles that are not PET or PETE numbered 3, 6 and 7 are the worst kind to eat anything from; they contain Bisphenol A (BPA), which is suspected of causing neurological and behavioral difficulties in fetuses and children. BPA simulates the hormone estrogen, which may have detrimental effects, including cancer of the brain, breast, and prostate, on the female reproductive system and the immune system in adults.

So, why the disinformation campaign by other colloidal silver sellers?

Answer:

Most nanoparticle colloidal silver sellers USE chemicals to make their products and HAVE to use glass bottles. Otherwise, the chemicals in their solutions will combine with the chemicals from the plastics and make worse chemical compounds that for sure are not good for your health.

There are a few companies that use plastic containers, or dark amber colored bottles that you cannot see through that may also contain BPA.

They do not want you to see the ugly chemical solutions in their colloids. Consumers should stay away from such harmful products.

We always use Safe Food Grade PET or PETE polyester bottles which is commonly used for carbonated beverage, water bottles and many food products. PET provides very good alcohol and essential oil barrier properties, generally good chemical resistance.
