Endpoint:
oxidising solids
Adequacy of study:
supporting study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
data from handbook or collection of data
Remarks:
Data from a peer-reviewed handbook, accepted as a reliable data source according to Chapter R.7A of REACH Guidance on information requirements and chemical safety assessment, adequate for assessment. Restrictions apply as not an experimental result.
Remarks on result:
not measured/tested

Uses:

Tanning leather, sizing paper, mordant in dyeing; purifying water; manufacture lakes, aluminum resinate; fireproofing and waterproofing cloth; clarifying oils and fats; treating sewage; waterproofing concrete; deodorizing and decolorizing petroleum; antiperspirants; agricultural pesticides; manufacture of aluminum salts.

Conclusions:
No oxidising hazard anticipated, as used as fireproofing agent for combustible material.
Executive summary:

A reference handbook, also cited in a reference database, provides a list of main uses of the substance, including fireproofing of clothes.

Endpoint:
oxidising solids
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because there are no chemical groups present in the molecule which are associated with oxidising properties and hence, the classification procedure does not need to be applied
Justification for type of information:
JUSTIFICATION FOR DATA WAIVING
In accordance with column 2 of REACh Annex VII, the study does not need to be conducted if the substance is incapable of reacting exothermically with combustible materials, for example on the basis of the chemical structure.
According to Regulation (EC) N°1272/2008 (CLP) criteria (Annex I §2.13.4./2.14.4., or as listed in the ECHA endpoint specific guidance on information requirements (R.7a, v6.0, July 2017, §R.7.1.13)), the substance contains electronegative atoms, oxygen, and though this element is not chemically bonded only to carbon and/or hydrogen, it is linked to aluminium, which is of low electronegativity, or sulfur, which is an electronegative element, but inorganic sulphates are not known to have oxidising properties (cf Bretherick's handbook of Reactive Chemical Hazards). Then oxidising properties are unlikely, and the classification procedure shall not apply, no further testing is required.

Description of key information

Low potential based on chemical structure and use as fireproofing agent.

Key value for chemical safety assessment

Oxidising properties:
no

Additional information

Based on the chemical structure, no oxidising properties are anticipated.

Moreover, supporting literature data indicates that the substance is used as a fireproofing agent, therefore as a weight of evidence, it should not enhance fire.

Justification for classification or non-classification

The chemical structure fulfills the exemption criteria of Regulation (EC) No.1272/2008 (CLP).
