Description of key information

Koc (MCI) = 12280000 - 449800000; log Koc = 7.09 - 8.65 (KOCWIN v2.00)

Key value for chemical safety assessment

Additional information

Experimental data on the adsorption potential of the substance are not available. Using KOCWIN Program v2.00 log Koc values were calculated based on log Kow and on the molecular connectivity index (MCI) (Blum, 2011). For the C8 FA component of Decanoic acid, mixed esters with neopentyl glycol and octanoic acid log Koc values of 7.09 (MCI) and of 6.68 (based on log Kow) were calculated. For the C10 FA component of Fatty acids, C8-10, triesters with trimethylolpropane the calculated log Koc values were 8.65 (MCI) and 8.31 (based on log Kow) respectively. The high log Koc values indicate a high potential for adsorption to soil and suspended matter.
