EPA found unreasonable risks to workers from 25 conditions of use of NMP. This chemical is commonly used commercially in the manufacture and production of electronics, agrichemicals, and petroleum products. Risks to workers can come from short-term and long-term inhalation, direct dermal exposure (through the skin) and vapor-through-skin exposure.
There are many solvents on the market, some of which might be suitable replacements for NMP depending on the condition of use. Alternatives to NMP will vary with the condition of use. EPA has done some analysis of alternatives to NMP with respect to commercial paint and coating removal products and a variety of alternatives are available. These include other chemical products as well as mechanical methods. In the coming months, EPA will perform additional work on identifying whether alternatives exist for other NMP uses.
EPA completed the final risk evaluation for NMP under amended TSCA in December 2020. The final risk evaluation for NMP determined that there are unreasonable risks to workers and consumers, for 26 out of 37 conditions of use.
The next step in the process required by TSCA is addressing these risks.
