Product Information from Born Free Bisphenol-A (BPA) is a chemical compound used to create polycarbonate plastic, a hard, clear plastic used widely in consumer products, including food and beverage containers. A growing body of scientific research suggests that small amounts of BPA may leach into foods or beverages stored in polycarbonate containers, especially when the contents are acidic, high in fat, or heated. Research suggests that BPA may act as an endocrine disruptor, a substance which mimics natural human hormones.
