BPA stands for bisphenol A. BPA is an industrial chemical that has been used to make certain plastics and resins since the 1960s. BPA is found in polycarbonate plastics and epoxy resins. Polycarbonate plastics are often used in containers that store food and beverages, such as water bottles.
There might be some confusion as to the true safety of plastics claiming to be BPA-free. Not only is Tritan™ a BPA-free plastic, it doesn’t contain BPS (bisphenol S) or any other bisphenols. Tritan has been tested by four third-party labs and shown to be free of any estrogenic and androgenic activity (EA-free). Combine that with shatter resistance, and you’ve got a tough plastic that is safe.
