Additional information

Experimental data on the adsorption potential of 1,2,3-propanetriyl triisooctadecanoate (CAS 26942-95-0) are not available. Values calculated with KOCWIN Program (v2.00) indicate a high adsorption potential (Birkhofer, 2014). Calculations based on the molecular conductivity index (MCI) resulted in a log Koc value of 13.96. Whereas based on the log Kow of the substance a log Koc value of 13.91 was calculated. The models have no universally accepted definition of the model domain, but since the substance is outside the log Kow range of the training set of the MCI and log Kow 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 Kow (> 10).
