What is Vinyl Acetate?

Vinyl acetate or vinyl acetate monomer (VAM) is a versatile and economically important building block chemical used to manufacture polymers that have with a wide variety of industrial and commercial applications.

What is the Vinyl Acetate Council?

The Vinyl Acetate Council (VAC) represents the North American manufactures and major processors of vinyl acetate monomer. VAC is dedicated to promoting the safe and continued use of vinyl acetate monomer (VAM) and VAM-based products.

VAC was formed in 1994 as a not-for-profit (501(c)(6)) tax exempt corporation, in the District of Columbia. VAC was previously known as the Vinyl Acetate Toxicology Group (VATG).

The VAC has a close working relationship with its European counterparts through the CEFIC Acetyls Sector Group.


The Mission of the VAC is to:

  • Collect and disseminate health, safety, and environmental information relevant to vinyl acetate.

  • Assess the need for additional information and sponsor studies accordingly.

  • Promote product stewardship with members and downstream users of vinyl acetate.

  • Monitor and participate in regulatory and other government proceedings with the potential to impact the safe and continued use of vinyl acetate.

Membership in the VAC is open to any manufacturer and processor/user of VAM. North American manufacturers aare eligible to be Full Members while all others are eligible to be Associate Members. Current members of the Vinyl Acetate Council include:

Acetaldehyde Working Group

Acetaldehyde is a significant metabolite of vinyl acetate. Given that the biologic properties of acetaldehyde tend to drive VAM’s human health risk assessment, the VAC formed the Acetaldehyde Working Group (AWG).

Membership in the AWG is open to all members of the VAC as well as companies and/or other organizations involved in the manufacture and/or emissions of acetaldehyde. In addition to the VAC, the following are members of the AWG: Eastman Chemical Company and the American Forest and Paper Association (www.afandpa.org).

One of the VAC's primary projects is to develop a pharmacokinetic model to further the risk assessment on vinyl acetate. Once completed, the risk assessment model should be of immediate use to EPA as they address vinyl acetate as a hazardous air pollutant. The VAC organized a Workshop with EPA to review the pharmacokinetics risk assessment model. The VAC routinely submits technical comments to research and regulatory agencies throughout the world, most notably the Environmental Protection Agency, International Agency for Research on Cancer and California Proposition 65 Office.
