Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Key result
- Type:
- log Pow
- Partition coefficient:
- >= -2.78 - < 1.23

Applicant's summary and conclusion
- Conclusions:
- log Kow calculated by EPIWIN program was -2.78 to 1.23 for postualted constituents but these data were not representative for the industrial product which is solubule >100 g/L and it is therefore assumed that major constituents have higher log Kow
- Executive summary:
log Kow calculated by EPIWIN program (KOWWIN v1.67 or v1.68) of the US EPA (Environmental protection Agency) QSAR vary over a broad range from -2.78 to 1.23
