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:
In accordance with column 2 of REACH Annex VII, the oxidising properties study does not need to be conducted as the substances are incapable of reacting exothermically with combustible materials on the basis of their chemical structures. According to the ECHA guidance (ECHA 2017), for organic substances or mixtures, the classification procedure for the oxidising solids hazard class need not be applied if: (a) the substance or mixture does not contain oxygen, fluorine or chlorine; or (b) the substance or mixture contains oxygen, fluorine or chlorine and these elements are chemically bonded only to carbon or hydrogen. For inorganic substances or mixtures, the classification procedure for this hazard class need not be applied if they do not contain oxygen or halogen. Any substance or mixture that complies with the above waiving criteria can be safely regarded to have no oxidising properties and, hence, need not be tested and need not be regarded as an oxidising solid.
The substances do contain oxygen atoms but they are covalently bonded to a carbon only. The substances are metal salts of fatty acids containing a metal ion which is ionically bonded to a carbonyl group when the salt is in its isolated form. However, the substances are almost exclusively produced and used directly in grease form where the substance is expected to be fully dissociated. Therefore, the substances are not considered to have oxidising properties.
