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:

Main component 1:
