Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

For complex mixtures a single value of Koc will not be definitive. Therefore, the estimation of the representativ constituent Koc values is presented:

Estimated value for the main component of the substance:

Koc   : 1E+010 L/kg (MCI method)

Key value for chemical safety assessment

Additional information

For complex mixtures a single value of Koc will not be definitive. Therefore, the estimation of the representative constituent’s Koc values is presented:
