Description of key information
logKoc: > 5 (KOCWIN v2.00)
Key value for chemical safety assessment
Additional information
No experimental studies are available for fatty acids, C16-18 (even numbered) and C16-18-unsatd. (even numbered), triesters with trimethylolpropane (CAS 68002-79-9) on adsorption/desorption. Using KOCWIN v2.00 with SMILES notations, a log Koc of 13.35 - 14.91 (estimate with MCI method) was calculated, indicating a high adsorption potential of the test substance. This result is supported by the read-across substance Ester reaction products of fatty acid, C5-10, pentaerythritol and dipentaerythritol, resulting in a log Koc of 4 - 7 established in a guideline study according to OECD 121 under GLP conditions. Taking all information into account it can be concluded that the potential for adsorption of fatty acids, C16-18 (even numbered) and C16-18-unsatd. (even numbered), triesters with trimethylolpropane is high.
