Description of key information

log Koc: 7.62 – 9.95 (KOCWIN v2.00)

Key value for chemical safety assessment

Additional information

No studies are available for fatty acids, C5-10 (linear and branched), tetraesters with pentaerythritol (CAS-No. 68424-31-7) on adsorption/desorption. Using KOCWIN v2.00 for the main components, log Koc values of 7.62 – 9.95 (estimate with MCI method) was calculated, indicating a high adsorption potential of the test substance. This result is supported by a read-across, on 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.
