Vinyl Acetate Added to CA Prop 65 Cancer List

Vinyl acetate has been added to California's Proposition 65 list of chemicals known to cause cancer by the Office of Environmental Health Hazard Assessment (OEHHA). This listing was done via the “State’s Qualified Experts” mechanism, based on the Carcinogen Identification Committee’s (CIC) determination that this chemical was shown to cause cancer. 

What is Vinyl Acetate?

Vinyl acetate is a colorless, flammable liquid with a sweet and fruity odor. It is a versatile chemical used in various industries, particularly for its adhesive and polymerizing properties.

Common items that may contain vinyl acetate include:

• Adhesives: glues, sealants, and tapes.
• Paints, Coatings, and Varnishes: used for durability and finish.
• Packaging Materials: certain plastics and films.
• Textiles and Treated Fabrics: polymer coatings for stain resistance or water-proofing.
• Industrial Resins and Emulsions: used in specialized manufacturing.
• Printing Inks: some inks incorporate vinyl acetate.

Impact on Businesses

As of January 3, 2026, businesses manufacturing, distributing, or selling products containing vinyl acetate must provide a clear warning label regarding potential health and environmental risks or meet reformulated standards that fall below established safe harbor levels.
