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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
