U.S. EPA Proposes a Significant New Use Rule on Alkylpyrrolidones (US)

On November 28, 2016 the U.S. EPA proposed a significant new use rule (SNUR) for two alkylpyrrolidones: N-ethylpyrrolidone (NEP) and N-isopropylpyrrolidone (NiPP).

SNUR for two alkypyrrolidone: the proposed significant new uses are any use of NiPP and any use of NEP except for the ongoing uses as a reactant in silicone seal remover, coatings, consumer and commercial paint primer, and adhesives. Individuals subject to the SNUR, in accordance with the Toxic Substance Control Act (TSCA), would be required to notify EPA at least 90 days before commencing any manufacturing or processing of the chemical substance for a significant new use.

The notification initiates EPA’s evaluation of the conditions of use within the applicable review period. Manufacture and processing for the significant new use is unable to commence until EPA has conducted a review of the notice, made an appropriate determination on the notice, and taken actions as are required in association with that determination.
