Additional information

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

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

Based on Reach regulation ANNEX IX column 2 "The study need not to be conducted if: the substance has a low potential for bioaccumulation (for instance a log Kow < 3) and/or a low potential to cross biological membranes". An estimated value with QSAR (Vega) has been proposed for a complete risk assessment.
