Waiving

Key value for chemical safety assessment

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 " Long-term toxicity testing shall be proposed by the registrant if the chemical safety assessment according to Annex I indicates the need to investigate further the effects on aquatic organisms."

Since the substance is readily biodegradable there is no concern for long term toxicity
