OEHHA adds developmental toxicity endpoint to Bisphenol S (BPS) Proposition 65 listing (effective Dec 8, 2025)

OEHHA issued a listing notice expanding the existing Proposition 65 reproductive toxicity listing for Bisphenol S (BPS) by adding the developmental toxicity endpoint. This change means Prop 65 warnings/enforcement considerations for BPS exposures now explicitly include developmental toxicity, in addition to previously covered reproductive toxicity endpoints, affecting product hazard assessments and warning determinations for businesses selling into California.
