EC A.14 (Statement):

Using C40H48O12S4as molecular formula and 849.06 g/mol as molecular weight, the oxygen balance for this major component was calculated to be –188 %.Using C80H96O24S8as molecular formula and 1698.12 g/mol as molecular weight, the oxygen balance for this minor component was calculated to be –188 %. The oxygen balance is for both components > –200% and therefore within the region where there may be a potential for explodability. However, the molecular structures of the test substance do not contain any
chemically instable or highly energetic groups that might lead to an explosion. There are no plosophores (bond
groupings known to give explosive properties) or auxoploses (explosive enhancing groups) present in the structure. The
relatively high oxygen balance (-188%) is considered due to the presence of a sulfonyl group in the molecule. Overall
consideration of the properties does not suggest a risk of explodability.

Applicant's summary and conclusion

Conclusions:
The test substance is not explosive.
