Description of key information

log Pow > 10  (KOWWIN v1.68)

Key value for chemical safety assessment

Additional information

The log Pow (12.02 - 13.98) of the substance 2-Butenedioic acid (2E)-, di-C12-14-alkyl esters (List No. 938-575-3) was determined by QSAR calculation with KOWWIN for both components (C12 and C14 diester component) which are the main components of the UVCB substance.

Due to the presence of long aliphatic chains, the substance is outside the applicability domain of the model (up to log Pow = ca. 10) and the result should be reported as log Pow > 10.
