Baby bottles from AVENT, Born Free, Green to Grow, Evenflo and Weil Baby all emit high or very high levels of hormone-altering chemicals, says new research published in the peer-reviewed journal Environmental Health. (1)
“Many PC-replacement-products made from acrylic, polystyrene, polyethersulfone, and Tritan resins leached chemicals with [estrogenic activity], including products made for use by babies. Exposure to various forms of UV radiation often increased the leaching of chemicals with estrogenic activity,” write the study authors.
The conclusion of the study will send shockwaves across the baby products industry, stunning many parents who thought “BPA-free” meant “free from all hormone-disrupting chemicals.”
The study authors write:
Many BPA-free PC- replacement products still leached chemicals having significant levels of estrogenic activity, as did BPA-containing PC counterparts they were meant to replace. That is, BPA-free did not mean [free from estrogenic activity].
UV rays unlock hormone-disrupting chemicals
An article published by Mother Jones (2) reports the research, revealing that ultraviolet rays (UV) activate and “unlock” hormone-mimicking chemicals in BPA-free bottles made out of polyester (PES) and Tritan, the materials most commonly used in BPA-free bottles.
Over the last several years, the negative press about the hormone-disrupting properties of BPA (Bisphenol-A) led to a wave of new “BPA-free” baby bottles, water bottles and sippy cups. But just because a bottle is free of BPA doesn’t means it’s free of other hormone-disrupting chemicals.
“Many of the items above are advertised as healthy alternatives to plastics containing BPA and the hormone-altering chemicals known as phthalates,” writes Mother Jones. “Born Free markets its baby products as the ‘natural choice for moms who want a safe, calm experience every time they feed their baby.’ Weil Baby claims that its bottles are made from ‘revolutionary new materials’ that are ‘ultra-safe.’ After UV exposure, CertiChem’s study found that both companies’ products leached potent synthetic estrogens.”
