non flammable

Key value for chemical safety assessment

Additional information

In accordance with section 1 of EC No 1907/2006 (REACH) Annex XI, the study does not need to be performed as based on chemical structure “Reaction product of thermal process between 1000°C and 2000°C of mainly aluminium oxide and calcium oxide based raw materials with at least CaO+Al2O3 >80% , in which aluminium oxide and calcium oxide in varying amounts are combined in various proportions into a multiphase crystalline matrix” is a non flammable solid. Pyrophoric properties and flammability in contact with water are not to be expected.

Justification for classification or non-classification

According to Regulation (EC) No 1272/2008 on classification, labelling and packaging (CLP) of substances and mixtures, the substance“Reaction product of thermal process between 1000°C and 2000°C of mainly aluminium oxide and calcium oxide based raw materials with at least CaO+Al2O3 >80% , in which aluminium oxide and calcium oxide in varying amounts are combined in various proportions into a multiphase crystalline matrix”is considered not to be a flammable solid.
