BPS (Bisphenol S)
Also: Bisphenol S · 4,4'-sulfonyldiphenol · BPA-free replacement · bis(4-hydroxyphenyl)sulfone
Avoid — the 'BPA-free' replacement with similar endocrine activity; not the upgrade marketing implies.
Testosterone & hormonal load
BPS was adopted widely as a BPA substitute after BPA bans, but research shows comparable estrogenic and anti-androgenic activity. BPS binds estrogen receptors and has been shown to disrupt steroidogenesis in cell models. Animal studies demonstrate reproductive and developmental effects at low doses. Its slower metabolism may actually lead to greater bioaccumulation than BPA.
