EPA Accepting Comments on Proposal to Delete MEK from Toxic-Pollutant List
The EPA said the plan to remove MEK from the HAP list is based on an initial determination that the compound is not believed to cause adverse human health or environmental effects.
The EPA's action is being taken in response to a petition submitted by the Ketones Panel of the American Chemistry Council (ACC) on behalf of MEK producers and consumers.

MEK is described as a low-boiling point, highly volatile, highly flammable liquid that is very soluble in water and miscible in organic solvents, and offers exceptionally high solvent powers for many natural and synthetic resins. Coatings-solvent uses include vinyl lacquers, nitrocellulose lacquers and acrylics.
