Reactive Groups
The appraisal of the molecular structure indicates no risk of rapid decomposition. MEXORYL SBU does not contain any of the structural features mentioned in the UN Recommendations. The occurrence of other chemical groups associated with explosive properties as described in the literature[1]was also considered. No such groups were present.
Oxygen Balance
The oxygen balance is not considered relevant for the evaluation of the explosive properties of this substance as it is not adequately characterized by taking into account carbon, hydrogen and oxygen only and omitting nitrogen.
Calometric Tests
The exothermic decomposition energy was determined using Differential Scanning Calorimetry in a closed, gold plated high pressure vessel (DSC). The result is shown in attached Figure1. The calorimetric test is of special importance for the evaluation of compounds containing chemical groups associated with explosive properties. Several small exothermic heat effects could be detected. The total decomposition energy (ΔHDec determined between room temperature and 500 °C) was found to be about 171 J/g thus being far below the UN limit of 500 J/g. The onset point of the first exothermic peak was at about 116°C.

Applicant's summary and conclusion
- Interpretation of results:
- non explosive
- Remarks:
- Migrated information
- Conclusions:
- Based on the chemical structure of the test material the result for the explosive properties has been predicted negative.
- Executive summary:
- Applying the internationally recognised UN Recommendation criteria, MEXORYL SBU is not to be classified as explosive material and no experimental determination according to the EC test guideline A.14 has to be performed.
Thus it can be concluded beyond a reasonable doubt, that MEXORYL SBU is not a potential explosive and does not have a potential for rapid energy release. Nevertheless, this judgment is in respect to classification; it does not necessarily mean that any processing hazards can be discounted.
