Assessing and Managing Chemicals under TSCA

Risk Evaluation for N-Methylpyrrolidone (NMP)

N-Methylpyrrolidone (NMP), also called n-methyl-2-pyrrolidone or 1-methyl-2-pyrrolidone, is a solvent used in a wide range of industrial and commercial applications, such as petrochemical processing, plastics, coatings (i.e., resins, paints, finishes, inks and enamels), electronics and other chemical manufacturing, paint removal, and industrial and consumer cleaning. NMP is found in several consumer products, including paint removal products, auto care products, home cleaning products, and arts and craft materials.

EPA will publish and take public comment on a Problem Formulation document for NMP which will refine the current scope, as an additional interim step, prior to publication the draft risk evaluation. This problem formulation is expected to be released within approximately six months of publication of the scope documents.
