Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Perfluoro-N-methylmorpholine (PMM) is not expected to be toxic to activated sludge at the limit of water solubility.  Activated sludge 3-hour EC50 (respiration inhibition): >1000 mg/L (nominal) by OECD 209.

Key value for chemical safety assessment

Additional information

PMM is the most water soluble member of the Perfluorinated Organic Chemicals, C5-C18 category. The 3-hour EC50 (OECD 209) based on nominal concentration was in excess of 1000 mg/L. No toxic effects were observed at this loading rate. An additional study was methodologically flawed and is not considered further.
