OEHHA adds vinyl acetate to the Proposition 65 list as a chemical known to cause cancer (warnings enforceable starting Jan 3, 2026)

OEHHA listed vinyl acetate under Proposition 65 as a chemical known to cause cancer (listing effective January 3, 2025). The Prop 65 warning requirement for significant exposures becomes enforceable starting January 3, 2026 (one-year grace period typical for new listings). Compliance teams should assess products/operations that may expose California consumers/workers to vinyl acetate and implement compliant Prop 65 warnings and related substantiation/documentation before the enforceability date.
