Vinyl Acetate Added to CA Prop 65 List!
Publisher:Admin  Source:  Date:2025/6/10

On January 3, 2025, the Office of Environmental Health Hazard Assessment (OEHHA) has added vinyl acetate to the Proposition 65 list as a carcinogen. This listing was done via the “State’s Qualified Experts” mechanism, based on the Carcinogen Identification Committee’s (CIC) determination that this chemical was clearly shown to cause cancer. 

 

The warning requirement for significant exposures to vinyl acetate will take effect on January 3, 2026.

 

What is Vinyl Acetate?

Vinyl acetate is a colorless, flammable liquid with a sweet and fruity odor. It is primarily used in the production of other chemicals used in various industrial and consumer product applications. Vinyl acetate-based polymers, including vinyl chloride-vinyl acetate copolymer, polyvinyl acetate (PVA), and polyvinyl alcohol (PVOH), are used in a variety of applications.

 

Common items that may contain vinyl acetate include:

Adhesives and Glues: PVA has strong adhesion properties for a variety of materials, including paper, wood, plastic films and metals, and is a key ingredient in wood glue, white glue, carpenter’s glue and school glue.

• Paints, Coatings, and Varnishes: VAM-based polymers are used in the production of many interior latex paints as the ingredient that provide adhesion of all the ingredients and the luster of the finish.

• Textiles: PVOH is used in textile manufacturing for warp sizing, a process by which textiles are coated with a protective film to minimize breakage during weaving.

• Packaging Materials: PVOH is used for adhesive packaging films.

• Plastic: Vinyl acetate is consumed in the manufacture of ethylene vinyl acetate (EVA), used in wire, cable insulation and footwear due to its flexibility, durability and its flame-retardant properties.
