About Bisphenol A (BPA)

In 2004 Klean Kanteen created the first BPA-free metal bottle for personal hydration to give consumers a safe, reusable alternative to the polycarbonate and lined aluminum bottles on the market. We use high quality, food-grade stainless steel because it's time-tested and is superior in strength, durability and safety to aluminum or plastic.

Since we founded Klean Kanteen, the health risks of BPA exposure have become an issue of concern to the general public as well as state and federal regulatory agencies. We created this page to help you keep up with the breaking news and also to give you resources to help you limit your exposure to this dangerous chemical and protect yourself and your family. We care about more than just the bottom line, and that's why a Klean Kanteen® is more than just a bottle.

What is bisphenol A (BPA)?

BPA-FreeBPA is a chemical compound used in manufacturing polycarbonate plastic and epoxy resins. It is used in baby bottles, water bottles, medical and dental devices, lenses, food storage containers, household electronics, compact discs, DVDs and countless other everyday items. Epoxy resins containing BPA are used to coat the inside of many food and beverage cans, as well as some aluminum water bottles.

BPA is an endocrine disruptor that mimics estrogen. To date, more than 200 studies have found evidence that exposure to BPA, even at extremely low levels, is linked to numerous diseases and health problems because it can interfere with the body's hormonal system. It's dangerous for adults, but it's even more dangerous for infants and children because they're still developing and growing. Due to this clear and compelling evidence, regulatory agencies in the United States are taking action to lower consumer exposure to BPA.

  • Following two expert panel meetings, the National Toxicology Program (NTP) provided descriptions and conclusions of the BPA evaluation and recommendations for future studies. Through its evaluation process, the NTP concluded there is "some concern" about effects of BPA on the brain, behavior, and prostate gland of fetuses, infants, and children at current human exposure levels. In the following months, evidence about the adverse health effects of BPA continued to mount as scientists outside NTP-CERHR conducted new studies and reviewed hundreds of previous studies linking BPA exposure to a wide array of illness and disease, including breast cancer, heart disease, obesity, diabetes, liver abnormalities and prostate cancer.
