Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

calculation (if not (Q)SAR)
Remarks:
Migrated phrase: estimated by calculation
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: An assessment of the substance was carried out based on an examination of the composition of the substance and the molecular structure of its known constituents.
Qualifier:
no guideline required
Principles of method if other than guideline:
An assessment of the substance was carried out based on an examination of the composition of the substance and the molecular structure of its known constituents.
GLP compliance:
no
Sample tested:
other: not applicable
Parameter:
other: An assessment was carried out based on an examination of the functionality within the substance, to identify the presence of elements commonly associated with oxidising behaviour.
Remarks on result:
other: see 'other information on results'

The substance does not contain chlorine or fluorine but does contain oxygen bound to silicon, magnesium and aluminium. The oxygen bound to the latter three elements forms part of a strong crystal lattice (lattice potential energy = 94, 733 kJ/mol). The oxygen is not available without breaking the lattice apart which would require extreme conditions. That the substance will not act as an oxidising agent is supported by the fact that it is used extensively as a refractory material due to its inherent lack of reactivity and very high thermal stability.

Interpretation of results:
GHS criteria not met
Conclusions:
It is concluded that the substance does not have any oxidising potential and does not require classification as an oxidising agent.
Executive summary:

An assessment of the substance was carried out based on an examination of the composition of the substance and the molecular structure of its known constituents. It is concluded that the substance does not have any oxidising potential and does not require classification as an oxidising agent.

Description of key information

It is concluded that the substance does not have any oxidising potential and does not require classification as an oxidising agent.

Key value for chemical safety assessment

Oxidising properties:
no

Additional information

An assessment of the substance was carried out based on an examination of the composition of the substance and the molecular structure of its known constituents. It is concluded that the substance does not have any oxidising potential and does not require classification as an oxidising agent.

Justification for classification or non-classification

The substance does not contain fluorine or chlorine. The oxygen in the substance is bound to silicon and extreme conditions would be required to release the oxygen.
