Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

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

Description of key information

Non oxidising

Key value for chemical safety assessment

Oxidising properties:
non oxidising

Additional information

The substance contains 6 oxygen atoms; these 6 oxygen atoms do not constitute a high proportion of the molecule (20.2% by weight; 18.8% of all heavy atoms; 7.8% of all atoms). Three oxygen atoms are bound to carbon and hydrogen (the hydroxyl groups in TEA; such oxygen atoms are not considered oxidizing. Three oxygen atoms are bound to sulfur as part of the benzenesulfonic acid group. Sulfur in a benzenesulfonic acid group is not considered an electronegative atom; besides organic sulfonic acid groups are not known to possess oxidizing properties; moreover, sulfates (salts) and sulfonates (salts) are not known to be oxidizing. Since the substance does not contain any other electronegative atoms bound to atoms in a high oxidation state, or bound or other electronegative atoms, does not contain any of the groups explicitly mentioned in the UK HSE's GUIDELINES FOR THE DETERMINATION OF OXIDIZING PROPERTIES, and has an oxygen balance of -217, it can safely be stated that it does not possess oxidizing properties.

Justification for classification or non-classification

No classification, the substance is a non oxidising solid.
