Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Reference
Endpoint:
explosive properties of explosives
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 explosive properties. As the UVCB-Reaction products of boric acid and lithium hydroxide 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 explosive 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 conducted.
Remarks:
No groups identified associated with explosive properties.
Interpretation of results:
GHS criteria not met
Conclusions:
The UVCB-Reaction products of boric acid and lithium hydroxide contains no functional groups imparting explosive properties. It is beyond reasonable doubt that the material will not exhibit explosive properties.
Executive summary:

According to the OECD testing methods publication, test A14 need not be carried out when examination of the structural formula establishes beyond reasonable doubt that the substance has no explosive properties. A theoretical assessment was performed on dilithium tetraborate and concluded that the substance contained no functional groups imparting explosive properties. As the UVCB-Reaction products of boric acid and lithium hydroxide 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. It is beyond reasonable doubt that the material will not exhibit explosive properties.

Description of key information

A theoretical assessment was performed on dilithium tetraborate and concluded that the substance contained no functional groups imparting explosive 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 explosive potential of these substances. It is beyond reasonable doubt that the material will not exhibit explosive properties.

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

Justification for classification or non-classification

Examination of the structural formula for dilithium tetraborate indicated that there are no chemical groups associated with explosive properties. As the UVCB-Reaction products of boric acid and lithium hydroxide contains the same functional groups as dilithium tetraborate it is expected to non-explosive too. In addition, the substance is inorganic and the oxygen balance is therefore not applicable. Based on this combination of factors, it is beyond reasonable doubt that the material will not exhibit explosive properties. No classification is therefore required.
