Description of key information

In accordance with column 2 of REACH Annex VII, the study (required in section 7.13) does not need to be conducted as the substance (on the basis of chemical structure) is incapable of reacting exothermically with combustible materials (i.e. it does not contain halogen atoms, and the oxygen elements are not chemically bonded to nitrogen or oxygen). 

Key value for chemical safety assessment

Oxidising properties:
no

Additional information

In accordance with column 2 of REACH Annex VII, the study (required in section 7.13) does not need to be conducted as the substance (on the basis of chemical structure) is incapable of reacting exothermically with combustible materials (i.e. it does not contain halogen atoms, and the oxygen elements are not chemically bonded to nitrogen or oxygen).

In addition, the oxidising properties of trisodium EDDS have been assessed from its structural formula. According to an Expert statement, trisodium EDDS does not contain any reactive groups that might lead to spontaneous oxidation of combustible products. Therefore, it can be concluded that trisodium EDDS has no oxidising properties (van Helvoirt, 1993g). [Data on trisodium EDDS is considered relevant to use for understanding the potential oxidising properties of EDDS acid, and is acceptable for using as read-across information].

Justification for classification or non-classification

EDDS acid and its trisodium salt contain no fluorine or chlorine, and the oxygen elements are chemically bonded to carbon or hydrogen, therefore neither would be classified as oxidising according to EU CLP or DSD regulations.
