Bisphenol A (BPA) is a synthetic compound produced for use in plastics and epoxy resins and coatings. BPA is employed in a wide range of consumer goods, and is used to make plastics clear, strong, and rigid. It is also a precursor for epoxy resins used in food cans and many other applications. BPA is absorbed readily by the body, and most exposure occurs through consumption and BPA can also be absorbed through the skin. BPA is so ubiquitous that although it is eliminated by the body relatively quickly, it is always present in the body (NIEHS 2016).
Bisphenol S (BPS) is a synthetic compound used in plastics and resin and coatings. BPS is found in many consumer goods, including plastics, food packaging, receipt paper, and industrial applications.
BPS is similar structurally to the better-studied chemical BPA, and is usually considered an alternative to BPA in plastics and resins. While the status of BPA as an endocrine-disrupting chemical is well-supported in research, BPS has received little investigation on its effects on the human body. Despite the more lax regulation on the use of BPS, the chemical similarity of BPA and BPS and new research suggest that BPS may be just as active in the body as an endocrine -disruptor (Rochester and Bolden 2015).
