Description of key information

log Koc (based on molecular connectivity index (MCI))= 3.1-4.7 (KOCWIN 2.00)

Key value for chemical safety assessment

Additional information

No experimental data investigating the adsorption potential of Fatty acids, C12-16 (even numbered) and C18 unstd., methyl esters (CAS No. 1234694-02-0) are available. As the substance is a complex UVCB substance, QSAR calculations covering representative fatty acid components (C12, C16 and C18 unsaturated) were performed with KOCWIN v2.00 and resulted in log Koc values ranging from 3.1-4.7 (C12 and C18 components respectively)(López Parrón, 2011). These values indicate that Fatty acids, C12-16 (even numbered) and C18 unstd., methyl esters is expected to exhibit potential for adsorption to organic soil and sediment particles.
