Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Compositional complexity of the substance makes experimental determination of a single Kow value impossible.  In addition, the substance has been determined to have surface-active properties, rendering both of the standard Kow test methods, HPLC and shake-flask, inapplicable and potentially making Kow estimation from separate water and octanol solubilities unreliable.  A combination of QSAR calculated and other reported values for substance constituents (taken to be applicable at 25C and one atmosphere pressure) has therefore been used to determine a log Kow range applicable to the whole substance.

Key value for chemical safety assessment

Additional information

The low Kow range has been determined to be -0.82 to 0.71.
