Description of key information
Values were estimated from the chemical structure of the three main components of Fatty acids, C12-20 and C12-20-unsatd., 2-ethylhexyl esters (CAS: 91001-42-2). According to KOCWIN the estimated Log Koc of Fatty acids, C12-20 and C12-20-unsatd., 2-ethylhexyl esters were between Log Koc 6.4655 (Koc Estimate from MCI) and between Log Koc 6.9163 - Log Koc 7.1541 (Koc Estimate from Log Kow).
Key value for chemical safety assessment
- Koc at 20 °C:
- 14 260 000
Additional information
The substance Fatty acids, C12-20 and C12-20-unsatd., 2-ethylhexyl esters (CAS: 91001-42-2) was determined to have a Log P value of greater than 5.7 and therefore can not be expected to have a low adsorption potential to soil.
Values were estimated from the chemical structure of the three main components of Fatty acids, C12-20 and C12-20-unsatd., 2-ethylhexyl esters (CAS: 91001-42-2). According to KOCWIN the estimated Log Koc of Fatty acids, C12-20 and C12-20-unsatd., 2-ethylhexyl esters were between Log Koc 6.4655 (Koc Estimate from MCI) and between Log Koc 6.9163 - Log Koc 7.1541 (Koc Estimate from Log Kow).
