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.

Additional information

Perfluoromethylmorpholine (PMM) is a volatile substance of low water solubility and high Henry's Law constant. It is expected to reside in the atmospheric compartment based on volatility and registered uses that would release this substance solely to air. It is not expected to partition from the atmosphere to terrestrial or aquatic compartments. Its degradation pathway is expected to be predominantly direct photolysis in the atmosphere, with an atmospheric lifetime in the range of 1600 – 4000 years. We have proposed to waive testing of hydrolysis based on extremely low water solubility, and hydrolysis is not a relevant degradation process in the environment due to non-presence of PMM in aquatic systems.
