EPA Draft Risk Evaluation of 1,4-Dioxane.

Impact/Purpose:

The focus of the public meeting is to peer review EPA's draft risk evaluation of 1,4-Dioxane.

Description:

1,4-Dioxane is used primarily as a solvent in industrial and commercial processes, such as in the manufacture of other chemicals, as a processing aid, a laboratory chemical reagent, and in adhesives and sealants. Historically, 90% of 1,4-dioxane production was used as a stabilizer in chlorinated solvents such as 1,1,1-trichloroethane (TCA). The 2016 Chemical Data Reporting data shows that there were two manufacturers producing or importing over 1 million pounds in the U.S. in 2015.
