Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

The octanol-water partition coefficient for possible constituents of EUF was calculated using KOWWIN v1.67 (Syracuse Reasearch Corporation, SRC).

The result was confirmed by an experimental study according to OECD 107 (flask method), where nitrogen was measured instead of the test substance in both water and 1-octanol phase. As the mean log Pow was -2.13 the complete amount of nitrogen-containing components retained in the water phase and no transition into the octanol phase occured.
