OEHHA adds developmental toxicity endpoint to the existing Proposition 65 reproductive toxicity listing for bisphenol S (BPS)

OEHHA expanded the scope of the existing Proposition 65 reproductive toxicity listing for bisphenol S (BPS) by adding the developmental toxicity endpoint (effective December 8, 2025) via the State’s Qualified Experts mechanism (DARTIC). Compliance teams should reassess whether exposures to BPS trigger Prop 65 warning obligations considering the expanded reproductive toxicity endpoint and ensure warnings/supply chain communications remain accurate.
