Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Applicant's summary and conclusion

Interpretation of results:
non explosive
Migrated information
Based on the information and review of the above substance, it is deemed not to be potentially explosive, based on the chemical structure and oxygen balance values.
Executive summary:

The explosive properties of the substance has been assessed by review of the functional groups of the chemical structure and oxygen balance. The substance is considered to contain no functional groups and an oxygen balance that would sustain explosive properties. It is therefore predicted that the substance does not possess explosive properties and it is therefore considered not scientically justified to conduct a full study.
