BPA is a chemical compound used in the production of polycarbonate plastics and epoxy resins. These materials are commonly found in a variety of consumer goods, such as water bottles, food storage containers, and the linings of metal food cans.

BPA is known for its ability to make plastics clear and durable, but it has raised health concerns due to its estrogen-mimicking properties, which can potentially affect the endocrine system and lead to various health issues. In response to these concerns, many manufacturers now offer BPA-free products, and regulatory agencies have issued guidelines to limit BPA exposure, especially in products intended for children and infants.
