Description of key information

Additional information

There are no experimental studies assessing the adsorption/desorption of docosyl docosanoate (CAS 17671-27-1). Therefore, the log Koc was calculated by (Q)SAR (EPI Suite v4.11), using the KOCWIN v2.00 model based on the Molecular Connectivity Index (MCI) and the log Kow method. Since the substance only partially falls within the applicability domain of both methods due to its high, estimated log Kow (14.61, KOWWIN v1.68), the reported results are not fully reliable and should be treated with caution. The estimation based on the MCI method resulted in a log Koc value of 11.19 and the log Kow method resulted in a slightly higher value of 12.20. Both models indicate a high potential for adsorption of docosyl docosanoate, which is in line with the high log Kow. The log Koc obtained by the MCI method is retained as key value.

Hence, based on the physico-chemical properties, the substance is expected to preferentially distribute into the sediment and soil compartment.
