Additional information

For this endpoint, the read across between PWH/ammonium and PWH/sodium salt is valid.

The read across justification is attached on section 13 of the dossier.

According to annex IX column 2 of REACH Regulation the test is not required as the substance is a salt completely dissociated in water.
