Key value for chemical safety assessment

Log Kow (Log Pow):
8.09

Additional information

The partition coefficient of the substance 2 -butenedioic acid (E)-, di-C8 -18 -alkyl esters (CAS 68610 -90 -7) was estimated using calculated data (KOWWIN v1.68) in a weight of evidence approach. The log Pow values of single boundary components C8 and C18 were calculated and the results were 8.09 and 17.91, respectively. Even if the contribution of the component C8 (a small fraction of the whole substance) is below the applicability domain limit of ca. 10, it can be concluded that the substance is highly lipophilic and the overall log Pow is greater than 10.
