OEHHA adds vinyl acetate to Proposition 65 list as a carcinogen; warnings required for significant exposures starting Jan 3, 2026

OEHHA has added vinyl acetate to the Proposition 65 list as a chemical known to the State of California to cause cancer. For compliance teams, this triggers the one-year lead time before consumer-product/occupational exposure warnings are required for significant exposures. Businesses selling products into California should evaluate potential exposures to vinyl acetate and update Proposition 65 warning determinations and labeling/online warning content by the stated warning-effective date.
