Description of key information

Sulphamidic acid is not oxidising based on assessment of chemical structure

Key value for chemical safety assessment

Oxidising properties:

Additional information

The molecule does not contain fluorine or chlorine, and only contains oxygen atoms bonded to sulfur.

Comparison of the functional groups listed in the ECHA guidance on CSA, Chapter R.7a, May 2008, Table R.7.1-29, with the chemical structure indicates no functional groups which have been associated with oxidising properties.

As a result, and according to Regulation (EC) No. 1907/2006, Annex VII, 7.13, column 2, testing for this endpoint is considered to be unnecessary based on the chemical structure.

Justification for classification or non-classification

The substance is not considered oxidising according to the criteria given in test method A17, Oxidising Properties (Solids), section 1.1, paragraph 2 (examination of the chemical structure) in Regulation (EC) No. 440/2008. As a result sulphamidic acid does not meet the criteria for classification under Directive 67/548/EEC, as amended for the 28th time in Directive 2001/59/EC, Annex VI, 2.2.2.


According to the additional criteria for classification under Regulation (EC) No. 1272/2008, Annex I, part 2, 2.14.4, if the molecule does not contain oxygen, fluorine or chlorine, or contains these atoms only bonded to carbon or hydrogen, then testing is not required. As a result, this substance does not meet the criteria for classification under Regulation (EC) No. 1272/2008.
