Effective December 29, 2024, the Office of Environmental Health Hazard Assessment (OEHHA) will mandate a warning requirement for significant exposures to bisphenol S (BPS). BPS was added to the Proposition 65 list as a reproductive toxicant (female reproductive endpoint) in 2023.

This listing was done via the “State’s Qualified Experts” mechanism, based on the Developmental and Reproductive Toxicant Identification Committee’s (DARTIC) determination that this chemical was clearly shown to cause female reproductive toxicity.

A complete, updated Proposition 65 chemical list is available on the OEHHA website.
