Applicant's summary and conclusion

Interpretation of results:
other: no oxidising properties
Migrated information
Based on the information and review of the above substance, it is deemed not to be potentially oxidising, based on the chemical structure and oxygen balance
Executive summary:

The oxidising 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 oxidising properties. It is therefore predicted that the substance does not possess oxidising properties and it is therefore considered not scientically justified to conduct a full study.
