Description of key information

log Koc: 2.5 - 3.1 (KOCWIN v2.00)

Key value for chemical safety assessment

Additional information

No studies investigating the adsorption/desorption behaviour of Dibutyl adipate (CAS 105-99-7) are available. Using KOCWIN Program (v2.00), log Koc values of 2.54 and 3.10 were calculated based on the molecular conductivity index (MCI) and the log Kow, respectively (Hopp, 2011). The results of the QSAR calculation are considered appropriate as the substance is within the applicability domain of the used model. Based on this information and considering the worst case assumption, it can be assumed that Dibutyl adipate has an adsorption potential.
