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 C18-unsatd., branched and linear, di- and triesters with trimethylolpropane (former CAS 85005-23-8). Using KOCWIN v2.00 with SMILES notation, log Koc values of 11.6 – 14.5 (estimate with MCI method) was calculated, indicating a high adsorption potential of the test substance. This result is supported by a read-across study 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). An expert statement on adsorption/desorption for Fatty acids, C16-18 (even numbered) and C18-unsatd., branched and linear, di- and triesters with trimethylolpropane (former CAS 85005-23-8) is available, indicating that a study is even technically not feasible due to the low very water solubility (Brekelmans, 1997).
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).
