Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The water solubility was visually assessed to be <1.07 mg/l. An experimental value for water solubility could not be obtained (DMOP formed a  suspension and would not dissolve at a concentration of 1.07 mg/l) therefore the value for water solubility was derived using the (Q)SAR WSKOW (V1.42) to be 0.0007656 mg/l. 
Note: This value differs from the value stated in the study report (Fox, 2013) derived using the (Q)SAR WSKOW (V1.42), as the log Kow value of 8.41 (Fox, 2013) and the melting point 42°C (Clipston, 2013) were entered into the (Q)SAR to derive the water solubility. 0.0007656 mg/l is considered to be more accurate as test data were used to derive the result using WSKOW (V1.42).
