Applicant's summary and conclusion
- Conclusions:
- N-(n-octyl)-2-pyrrolidinone is not classified.
- Executive summary:
The migrated NONS file does not provide details on the guideline followed, or whether the study is GLP. The NOEL and NOAEL are both found to be 55 mg/kg bw/day. This is not at a level which provides a classification.
