Just when you thought you’d learned everything there was to learn about how to avoid bisphenol-A (BPA), and how to go BPA-free, the endocrine-disrupting plastics chemical, new research shows that there’s more hormone-disrupting bisphenols around you than you probably thought.
In answer to consumers’ demands to drop BPA from products, many manufacturers have simply switched to using a different — but equally toxic and perhaps even more toxic — chemical called bisphenol-S (BPS).
It May Be BPA-Free, But What About BPS?
BPA, an estrogenic plastic by-product used in the manufacture of polycarbonate plastics, can leach into food or drinks from the plastic containers holding them. BPA has been identified as an estrogen-mimicking compound since the 1930s, and is known to be particularly dangerous for pregnant women, infants, and children. In fact, in the early 1930s BPA was used as an artificial estrogen to not only fatten poultry and cattle, but as a form of estrogen replacement therapy for women of the times. It was only in the 1940s that Bayer and General Electric used BPA to harden polycarbonate plastics and make epoxy resin.
It has since become one of the world’s highest production volume chemicals and has been widely reported in the media as being a suspected disruptor of your body’s hormones.
Canada, in September 2010, declared BPA as a toxic substance, but to date no other country has followed suit, although BPA has been banned in baby bottles in Europe and the United States. As a result of the widespread consumer backlash, however, many companies have rolled out “BPA-free” plastic products, ranging from bottles and sippy cups to reusable water bottles, meant to appeal to those health-conscious consumers looking to avoid toxins.
Unfortunately, this may be just a ruse, as studies now show that BPS is showing up in human urine concentrations at levels similar to those of BPA. This suggests that many manufacturers are simply swapping one bisphenol for another.
BPS May Be Less Known, But That Doesn’t Make It Less Toxic
Similar to the way food manufacturers label a bag of gummy bears as “fat-free,” implying it’s good for you while staying silent about the massive amounts of sugar they contain, plastics manufacturers can legally make it appear their products are safe by labeling them BPA-free, even though they may contain BPS, or another similar toxic chemical, that they don’t mention. More corporate lies of omission that can and do hurt your health.
In the case of BPS, there’s reason to believe it is just as dangerous to human health, and possibly more so, than BPA, although the research is not nearly as abundant just yet. Writing in the journal Toxicology In Vitro, researchers stated:
In 2011, the European Commission has restricted the use of Bisphenol A in plastic infant feeding bottles. In a response to this restriction, Bisphenol S is now often used as a component of plastic substitutes for the production of baby bottles. One of the major concerns leading to the restriction of Bisphenol A was its weak estrogenic activity. By using two highly standardised transactivation assays, we could demonstrate that the estrogenic activity of Bisphenol A and Bisphenol S is of a comparable potency.
Not only does BPS appear to have similar hormone-mimicking characteristics to BPA, but research suggests it is actually significantly less biodegradable, and more heat-stable and photo-resistant, than BPA. GreenMedInfo reports:
While regulators wait for manufacturers who promote their products with “BPA-Free!” stickers at the same moment that they infuse them with BPS to voluntarily reformulate, there is evidence now that BPS may actually have worse effects to environmental and human health, alike.
BPS’ relative inability to biodegrade indicates: 1) once it is absorbed into the human body, it may accumulate there for longer periods of time. 2) it is more likely to persist in the environment, making external exposures to it, and its many metabolites, much more likely than the faster degrading BPA. In other words, its potential to do harm will worsen along the axis of time, not lessen, which is a common argument made for the purported “safety” of BPA.
Just How Many Chemicals Are Lurking In Your BPA-Free Plastic?
You would think labeling a product “BPA-free” would be some measure of protection against ingesting toxic plastic by-products, but it turns out that tests on plastics using this label have not been conducted under real-world conditions like running the plastics through a dishwasher or heating them in a microwave.
In a study meant to simulate “real-world” use, 95 percent of all plastic products tested positive for estrogenic activity, meaning they can still disrupt your hormones even if they carry a BPA-free label. Even more disconcerting is the finding that BPA-free plastics in some cases leached more BPA than the non-BPA free plastics.
In some cases, instead of actually removing BPA from their products, manufacturers are only taking out a percentage of it, which means we’re still being exposed to it, only now in undisclosed amounts. The truth is there’s an alphabet soup of toxic chemicals in almost everything you come in contact with, from plastics to PVC water lines to canned goods, which are lined with BPA-containing plastic. Thermal receipt paper, all world paper currency, and those sealants your dentists want to put on you and your children’s teeth also are primary sources of BPA exposure.
But again, BPA is not the only culprit; it’s simply the most highly publicized one. There’s also bisphenol AB and AF, bisphenol B and BP, bisphenol C, bisphenol E, F, G, M, S, P, PH, TMC, and, yes, there’s even a bisphenol Z. Any one of these can be in your BPA-free baby bottle or sippy cup, unfortunately.

Who’s Minding The “BPA-Free” Store?
Now that BPA-free products are beginning to flood the market, you may be interested to know that we actually know relatively little about what’s really in these new plastics, and what little we do know comes right from the manufacturers. The Atlantic reported:
Because the U.S. system of regulating chemicals relies primarily on information supplied by a material’s manufacturer, we know relatively little about these new plastics.
Under the Toxic Substances Control Act (TSCA), the U.S. law that regulates chemicals in commerce, it’s entirely permissible to launch a new material into high-volume production without disclosing its precise chemical identity or any information about its toxicity. This makes it impossible for the public to assess product safety independently of manufacturer claims. And currently, despite EPA and FDA policies that support “safe” alternatives to a chemical of concern like BPA, neither federal agency conducts safety testing of new materials destined for consumer products before they come on the market.
So it’s very much an anything-goes attitude when it comes to the chemicals used in countless consumer products. Until the system changes – if the system changes – your safest bet is to avoid plastic products as much as possible.
Glass Is One Of The Best Alternatives
If you’re interested in avoiding any number of chemical toxins leaching into your food and beverages, choose glass over plastic, especially when it comes to products that will come into contact with food or beverages, or those intended for pregnant women, infants, and children. This applies to canned goods as well, which are a major source of BPA (and possibly other chemicals) exposure, so whenever you can, choose jarred goods over canned goods, or opt for fresh instead. Another good idea is to ditch plastic teething toys for your little ones and choose natural wood or fabric varieties instead.
To be fair, you probably can no longer completely eliminate your exposure to BPA, BPS, and similar toxins (since they’re likely in our air, water, and food, too) but you can certainly reduce your exposure dramatically by making informed choices like those described above.
