Reference
Endpoint:
oxidising solids
Type of information:
read-across based on grouping of substances (category approach)
Adequacy of study:
key study
Justification for type of information:
A theoretical assessment was performed on dilithium tetraborate and concluded that the substance contained no functional groups imparting oxidising properties. As lithium tetrahydroxyborate contains the same functional groups as dilithium tetraborate and any variations due to the range of trigonal and tetrahedral species between the substances are not expected to lead to any changes in the oxidising potential of these substances. Read-across to the theoretical statement on dilithium tetraborate is therefore proposed.
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 dilithium tetraborate.

On the basis of theoretical assessment, lithium tetrahydroxyborate (which contains identical functional groups to dilithium tetraborate) should also 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 theoretical assessment, lithium tetrahydroxyborate (which contains identical functional groups to dilithium tetraborate) 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.

Oxidising properties:

Additional information

Justification for classification or non-classification

A theoretical assessment was performed on one category member, dilithium tetraborate and concluded that the material meets all criteria for exemption from testing and has a structure not at all conducive with that required to exhibit oxidising tendencies. As the same functional groups are present across the category members, and any variations due to the range of trigonal and tetrahedral species between the substances are not expected to lead to any changes in oxidising potential of the substances then it can be concluded that no classification is therefore required across the lithium borate substances.
