Key value for chemical safety assessment

Additional information

The dissociation constant of the substance fatty acids, C18 unsatd., trimers, 2 ethylhexyl esters (CAS 173832-46-7) was determined by QSAR calculation with SPARC (v4.6) for the single components. No dissociation could be determined within the range pH = -0.2 - 14 for the di- and tri-2 -ethylhexyl esters FA components.
