N-methyl pyrrolidone: chemical profile. 1996.

TURI Technical Report No. 36. N-methyl pyrrolidone has been used in industry as a substitute for other undesirable solvents. In particular, it has been introduced as a less toxic and low volatility substitute for solvents such as methylene chloride and 1,1,1 trichloroethane, for applications such as paint removal, graffiti removal, cured urethane cleanup, and industrial degreasing. According to the EPA, although paint stripping accounts for only 10-15% of NMP used, it appears to offer the greatest potential for exposures because many of the other uses involve closed processes. Virtually all paint stripping chemicals and processes involve some form of health or safety risk.The exposure path of most concern to individuals is the dermal route. Exposure to NMP by inhalation is also possible.
