JUSTIFICATION FOR DATA WAIVING
As the substance to be registered, PMDA, is unstable in water (fast hydrolysis), the surface tension of an aqueous solution can not be measured. Therefore, the study was waived.

Description of key information

Test not performed; as the substance to be registered, PMDA, is unstable in water (fast hydrolysis), the surface tension of an aqueous solution cannot be measured. The corresponding hydrolysis product Pyromellitic acid (PMA) does not have surface-active properties in literature.

Key value for chemical safety assessment
