What it is + why it's regulated

Bisphenol S, or BPS, is a chemical used in many everyday products, such as plastics, thermal paper receipts, and food can linings. It is similar to BPA, which you may have heard of. The European Chemicals Agency (ECHA) lists BPS as a Substance of Very High Concern because it is an endocrine disruptor. This means it can interfere with the body's hormone systems, potentially affecting growth, reproduction, and development. BPS was added to the EU REACH Candidate List in 2024, which means companies must inform consumers if their products contain it above certain levels. This regulation helps you make informed choices.
