Description of key information

Zinc bis[12-hydroxyoctadecanoate] does not contain relevant functional groups for which a dissociation constant (pKa) could be determined.

Key value for chemical safety assessment

Additional information

In accordance with section 1, Annex XI of Regulation (EC) No 1907/2006, the study does not need to be conducted. The substance does not contain relevant functional groups for which a dissociation constant (pKa) could be determined. Therefore, the determination of a dissociation constant is not considered to be required (ECHA Guidance on information requirements and chemical safety assessment Chapter R.7a: Endpoint specific guidance, section R.7.1.17.1; November 2012).
