Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
