Description of key information

In accordance with section 2 of REACh Annex XI, the oxidising properties study is waived, as considered scientifically unjustified, based on the weight of evidence of the use of the substance as a fireproofing agent for combustible materials.

Key value for chemical safety assessment

Oxidising properties:

Additional information

Three handbooks provide information that alums in general, and ammonium aluminium sulfate in particular, are used for treatment, including fireproofing, of various combustible materials (wood, textiles, leather, paper, fur). Therefore it seems very unlikely that the substance could exhibit oxidising properties.

Justification for classification or non-classification

The substance is not anticipated to meet the criteria of Directive 67/548/EEC (DSD) nor of Regulation (EC) N°1272/2008 (CLP).
