Description of key information

The Koc and log Koc of  1,2,4-trimethylbenzene were calculated to be 1097 and 3.04 respectively.

Key value for chemical safety assessment

Koc at 20 °C:
1 097

Additional information

No reliable experimental study was identified therefore, Koc and Log Koc were calculated using the Log Kow of 3.63 in accordance with the method defined in the TGD. This method is deemed reliable and acceptable for assessment for this endpoint. Supporting study also available USEPA report (1994).
