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 the EU criteria, substance can be regarded as moderately soluble. The result is confirmed by the similar substance Paraffin waxes and Hydrocarbon waxes C14-17, chloro, sulfochlorinated, low sulphonated, saponified.

The water solubility Estimation, according to EPISUITE, WSKOW v1.42 is
