Summary: An overhaul in 2016 of the main U.S. chemical safety law, the Toxic Substances Control Act, required EPA to choose the first 10 chemicals for risk evaluation. NMP, one of the first 10 chemicals, is commonly used in paint and coating removal products but is also found in automotive products, inks, degreasers, and more. NMP is linked to fetal development problems, including low birth weight and birth defects.
In January 2017, EPA proposed a rule to restrict most uses of NMP in paint and coating removal products. Unfortunately, the agency recently indefinitely delayed finalization of this proposed restriction.
