The CLP Regulation uses the UN Global Harmonised System (GHS) and European Union Specific Hazard Statements (EUH). What is the Classification and Labelling Inventory? The molecular formula identifies each type of element by its chemical symbol and identifies the number of atoms of each element found in one discrete molecule of the substance. Substance identity Substance identity. Sulfated and tungstated stannias were prepared from commercial Sn-gels of meta-stannic acids; the former showed catalytic activities higher than those of the materials obtained from conventional gels and of sulfated zirconias.The latter led to the synthesis of a ceramics acid, calcined at >1000 °C, whose catalytic activity and acidity were intermediate between mordenite and silica–alumina. The source of the information is mentioned in the introductory sentence of the hazard statements. Note that for readability purposes, only the pictograms, signal words and hazard statements referred in more than 5% of the notifications under CLP are displayed. However, substance notifications in the InfoCard are aggregated independently of the impurities and additives. Substances may have impurities and additives that lead to different classifications. ECHA maintains the C&L Inventory, but does not review or verify the accuracy of the information. The CLP Regulation makes sure that the hazards presented by chemicals are clearly communicated to workers and consumers in the European Union.
