Description of key information

In accordance with column 2 of Annex VII of the REACH regulation, the substance tetrasodium 1-acetamido-2-hydroxy-3-(4-((4-sulphonatophenylazo)-7-sulphonato-1-naphthylazo))naphthalene-4,6-disulphonate (Common Name: Brilliant Black 1) is incapable of reacting exothermically with combustible materials on the basis of the chemical structure. It is an organic substance containing oxygen and no halogen and these elements are not chemically bonded to nitrogen or oxygen. Thus, the chemical is not expected to exhibit oxidising property.
