Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

logKoc: > 5 (KOCWIN v2.00)

Key value for chemical safety assessment

Additional information

No experimental studies investigating the adsorption potential of fatty acids, coco, di-and triesters with trimethylolpropane (CAS 85566-29-6) are available. Using KOCWIN v2.00 with SMILES notation, log Koc values of 10.2 - 13.35 (estimate with MCI method) was calculated, indicating a high adsorption potential of the test substance. This result is supported by a suitable read-across with the substance Ester reaction products of fatty acid, C5-10, pentaerythritol and dipentaerythritol, where a log Koc of 4 - 7 was established in a guideline study according to OECD 121 under GLP conditions (Sydney, 2008). Taking all information into account it can be concluded that the potential for adsorption of fatty acids, coco, di-and triesters with trimethylolpropane (CAS 85566-29-6) is high.
