Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
