Oxidising properties
Administrative data
Link to relevant study record(s)
- 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 the substance is incapable of reacting exothermically with combustible materials
- Endpoint:
- oxidising solids
- Type of information:
- other: Expert statement
- Adequacy of study:
- supporting study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- accepted calculation method
- Remarks:
- Expert statement
- Principles of method if other than guideline:
- Oxidising properties estimated from structural formula
- GLP compliance:
- not specified
- Key result
- Sample tested:
- other: From the structural formula it can be concluded that the substance has no oxidising properties
- Parameter:
- other: From the structural formula it can be concluded that the substance has no oxidising properties
- Remarks on result:
- mixture does not ignite and burn
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- From the structural formula it can be concluded that trisodium EDDS has no oxidising properties
- Executive summary:
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 combustable products.
Trisodium EDDS contains no fluorine or chlorine, and the oxygen elements are chemically bonded to carbon or hydrogen, therefore trisodium EDDS would not be classified as oxidising according to EU CLP regulation.

Description of key information
According to an Expert statement, it can be concluded (from its structural formula) that trisodium EDDS has no oxidising properties
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
Additional information
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).
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).
Justification for classification or non-classification
Trisodium EDDS contains no fluorine or chlorine, and the oxygen elements are chemically bonded to carbon or hydrogen, therefore trisodium EDDS would not be classified as oxidising according to EU CLP regulation.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
