Description of key information

log Koc: 10.78 – 31.13

Key value for chemical safety assessment

Additional information

Experimental data on the adsorption potential of Nonanoic acid, esters with adipic acid and trimethylolpropane are not available. The log Koc values of three main substance constituents were calculated using KOCWIN Program (v2.00). The model has no universally accepted definition of the model domain, but since not all main substance constituents fall within the log Kow range of the training set of the MCI model, the results should be taken with caution. The definite values may not be fully reliable, but indicate a high adsorption potential, which is also to be expected based on the high log Pow (log Pow > 6). Estimations based on the MCI method resulted in log Koc values ranging from 10.78 – 31.13.
