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.

Paraffin waxes and Hydrocarbon waxes, chloro, sulfochlorinated, saponified was tested for estimation of patition coefficient by EU A.8 method. The substance shows a partition coefficient about <1.05 based on sample solubility in pure water and n-octanol.
