Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

log Pow = 5.21 - > 10

Key value for chemical safety assessment

Additional information

The log pow of the substance fatty acids, lanolin, iso-Pr esters (CAS 63393-93-1) was determined by QSAR calculation with KOWWIN (v1.68) for the single components.

Due to the fact that C29iso and C29anteiso FA component is long chain hydrocarbon which exceeds the applicability domain of KOWWIN the value for log Pow is reported with restrictions.Therefore the partition coefficient for these components are deduced to be > 10.
