- Qualifier:
- according to guideline
- Guideline:
- EU Method A.17 (Oxidising Properties (Solids))
- Deviations:

- Key result
- Parameter:
- other: theoretical assessment
- Remarks on result:
- other: Theoretical assessment
- Remarks:
- No groups identified associated with oxidising properties.
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- On the basis of theoretical assessment, the material should be considered as not oxidising and should not be subjected to experimental testing. The material meets all criteria for exemption from testing and has a structure not at all conducive with that required to exhibit oxidising tendencies.
- Executive summary:
Test A17/ A21 need not be carried out when examination of the structural formula establishes beyond reasonable doubt that the substance has no oxidising properties. The supplement to A17/A21 method describes situations in which experimental assessment of oxidising properties is not necessary. A theoretical assessment was therefore carried out initially.
On the basis of theoretical assessment, it was concluded that the material should be considered as not oxidising and should not be subjected to experimental testing. The material meets all criteria for exemption from testing and has a structure not at all conducive with that required to exhibit oxidising tendencies.
Reference
Examining the structural formula, the following observations can be made:
(i) The molecule does not contain any functional groups imparting oxidising properties.
(ii) According to the two criteria quoted, oxidising properties can exist when:
- the electronegative atoms which are present constitute a high proportion of the molecule and are bound to elements in a high oxidation state. In the case of dilithium tetraborate the proportion of electronegative atoms in the molecule is high (7 oxygen atoms out of an overall atom count of 13). All oxygen atoms are bound to boron atoms.
-the electronegative atoms are bonded to each other or to other electronegative elements such as iodine, nitrogen, sulphur or phosphorus. In the case of dilithium tetraborate, the electronegative atoms are not bound to one another, nor to any other electronegative elements.
On the basis of this exercise, the material should be considered as not oxidising and should not be subjected to experimental testing. The material meets all criteria for exemption from testing and has a structure not at all conducive with that required to exhibit oxidising tendencies.
Description of key information
On the basis of a theoretical assessment, the material should be considered as not oxidising and should not be subjected to experimental testing. The material meets all criteria for exemption from testing and has a structure not at all conducive with that required to exhibit oxidising tendencies.
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
Additional information
Justification for classification or non-classification
Following a theoretical assessment, the material meets all criteria for exemption from testing and has a structure not at all conducive with that required to exhibit oxidising tendencies. Classification is therefore not required.
