Description of key information

Due to the UVCB character of the submission item, no meaningful dissociation constant exists and a measurement is technically not possible.

Key value for chemical safety assessment

Additional information

Testing of this endpoint has been waived on the basis of Annex IX, 2., as a study is considered technically not feasible and the dissociation constant is not a meaningful figure for a UVCB without major constituents.
