Description of key information

High adsorption potential of Fatty acids, C16-18, 2-ethylhexyl esters to soil and sediment particles (log Koc 6.7-7.3).

Key value for chemical safety assessment

Additional information

No studies are available for Fatty acids, C16-18, 2-ethylhexyl esters on adsorption/desorption. Using KOCWIN v2.00, log koc values of 6.7 -7.3 (estimate from log Kow) were calculated, indicating a high adsorption potential of the test substance. This result is supported by a read-across, on Fatty acids, C16-C18 and C18 unsatd., branched and linear, Bu esters (CAS 16391-32-8), where a log Koc >5.63 was established in a guideline study according to EU Method C.19 under GLP conditions (White and Mullee 2003).
