Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

For detailed information see attached Report.

The log Pow was calculated (QSAR) with KOWWIN. Due to the fact that this substance is a long chain hydrocarbon which exceeds the applicability domain of KOWWIN the value for log Pow is reported with restrictions.
The applicability domain covers log Pow up to 10 (maximum) so these values should be given as log Pow > 10.
The concrete value is reported to show the high lipophilic nature of the substance.

Description of key information

log Pow > 10 (QSAR, KOWWIN v1.68)

Key value for chemical safety assessment

Additional information

The log Pow of the substance was estimated by QSAR calculation with KOWWIN (v1.68) for the single components.

As the calculated value exceeds the applicability domain of the model, the value is reported as log Pow > 10.
