Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
The substance is not expected to be explosive based on the chemical structure of the substance and testing results with similar substances.
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
A waiving argument has been provided for the registered substance as the substance does not contain any chemical groups known to have explosive potential, therefore performing a study on the substance is scientifically unjustified in accordance with REACH Annex VII, Column 2. A read-across study on the similar substance silicon dioxide has been provided to support the waiving argument. The silicon dioxide was tested for explosivity in accordance with German national testing guideline VDI 2263 Part 1 (EN 14034 -3, 2006). The results of this study showed that the silicon dioxide was non explosive, which could be predicted by the lack of chemical groups associated with explosivity present in the substance. Read-across from silicon dioxide to silicic acid, aluminium, calcium, sodium salt was considered relevant due to the similarity of the structures of the substances.
Justification for classification or non-classification
The substance is not classified as explosive as it does not contain any chemical groups known to be associated with explosivity. In addition, the DSC of the substance did not show any exothermic events until 900°C and this only released 43 J/g, meaning the substance is considered thermally stable and not explosive.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
