Description of key information

The substance being highly insoluble, the log Koc were appraised by QSAR using log Kow value or based on MCI method. The results obtained showed that the log Koc calculated values of the test substance are ranged between 7.4 and 15.38.

Key value for chemical safety assessment

Additional information

The test substance being highly insoluble, QSAR (Kocwin v2.00) was runned to appraise fixed values for the constituents listed in section 1.2 of IUCLID.

The Log Koc values obtained with QSAR using log Kow value or based on MCI method were ranged from 7.4 to 15.38.

Log Koc value being not useful as no environmental CSA is required (see discussions in the CSR) and as no PNECs for soil and sedment being derived, no single exact log Koc value was selected.

The overall conclusion to be retained is: log Koc > 7.4
