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.
