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.

Based on reach regulation ANNEX VII column 2 " The study does not need to be conducted if: the substance is incapable of reacting exothermically with combustible materials"

Justification for classification or non-classification

According to the definition set out in the CLP Regulation (EC 1272/2008) oxidising solid means a solid substance or mixture which, while in itself is not necessarily combustible, may, generally by yielding oxygen, cause, or contribute to, the combustion of other material. A specific study has not been conducted on the substance but based on the chemical structure the substance is incapable of reacting exothermically with combustible materials, therefore no classification as oxidising is warranted.
