Key value for chemical safety assessment

Additional information

The dissociation constant of the substance isooctadecanoic acid, mono- and diester with glycerol (CAS 97358-80-0) was determined by QSAR calculation with SPARC (v4.6). No dissociation is to be expected under naturally relevant pH conditions (pH = 5 -9).
