EU: How to Comply with NMP (1-methyl2-pyrrolidone) Restriction, Guidance Document, July 2019

A document released by ECHA intends to help those who use 1-Methyl-2-pyrrolidone (NMP) or mixtures containing NMP (C ≥ 0.3%) , to comply with the restriction requirements under the REACH Regulation. Moreover this guidance may help the authorities to understand what is expected and evaluate the compliance at a site.

NMP has a harmonised classification as toxic to / for reproduction (reproductive toxicant category 1B) and is also a respiratory, skin and eye irritant. In Europe, NMP is subject to REACH Annex XVII restriction 71. If you have to use NMP in your workplace, you need to protect anyone that could be exposed to it. This guideline is intended to help you understand what you need to do to comply with the provisions of this restriction in its own right but also against the background of your existing occupational safety and health (OSH) obligations.

The general approach described in this guideline can be applied to other aprotic solvents similar to NMP (such as DMF and DMAC), if similar REACH restrictions are introduced for other aprotic solvents. Some elements of the guideline are NMP specific (e.g. good practice examples, monitoring methods, description of uses etc.) and therefore may not be directly applicable to other substances.”

A new guideline is available for industrial users of 1-methyl-2-pyrrolidone (NMP) to help them comply with the substance’s restriction requirements. The guideline is needed because this is the first restriction of its kind that is based on Derived no Effect Levels (DNEL).

NMP is used as a solvent or surface deposition medium during manufacturing and is therefore a critical substance for various industries producing batteries, semiconductors, fibres, pharmaceuticals and wire coatings. NMP users in these sectors will have to comply with the restriction by 9 May 2020. For NMP used in wire coatings, the deadline is 9 May 2024.

In close cooperation with stakeholders, ECHA has prepared the guideline to help companies, including SMEs, to manage the risks when using NMP at industrial sites. NMP is a reproductive toxicant (may damage the unborn child), it causes serious eye and skin irritation and it may cause respiratory irritation. Several consultations and round table workshops have been organised to identify good practice and find illustrative examples on how users of NMP can control exposure to NMP and comply with the restriction.

The general approach described in this guideline can also be applied to other aprotic solvents similar to NMP, such as DMF and DMAC, if similar REACH restrictions are introduced for other aprotic solvents at a later stage.
