Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Results and discussion

Percent distribution in media

Air (%):
20.8
Water (%):
78.9
Soil (%):
0.1
Sediment (%):
0.1

Any other information on results incl. tables

Over time, the substance will preferentially distribute into the compartments water (78.9%) and air (20.8%). However, since the calculation refers to the uncharged molecule, the model may underestimate the distribution into water under environmentally relevant conditions (pKa of ethylpropylamine = 11.0).
