Key value for chemical safety assessment

Additional information

The dissociation constant of the substance Multi constituent ester of pentaerythritol 2-ethylhexanoate was determined by QSAR calculation with SPARC (v4.6) for the diester, triester and tetraester components. No dissociation could be determined under naturally relevant pH conditions (pH 5 -9).
