Description
OEHHA added the developmental toxicity endpoint to the existing reproductive toxicity listing for Bisphenol S (BPS) under Proposition 65. This addition was made via the State's Qualified Experts listing mechanism based on the Developmental and Reproductive Toxicant Identification Committee's determination that BPS was clearly shown to cause developmental toxicity. Products containing BPS sold in California may now require warnings for developmental toxicity exposures in addition to reproductive toxicity.
