Description of key information
In accordance with column 2 of Annex VII of the REACH regulation, the substance 4-amino-5-hydroxynaphthalene-1,7-disulphonic acid is incapable of reacting exothermically with combustible materials,on the basis of the chemical structure. It is an organic substance containing oxygen but no halogen atoms. However, these elements are not chemically bonded to nitrogen or oxygen. THus, the chemical is unlikely to exhibit oxidising properties and this study was therefore considered for waiver. For the purpose of chemical safety assessment, the chemical is considered as "Not Oxidising".
