The resultant DSC trace showed two small exothermic events, however, their combined magnitude was 216 J/g which is significantly less than the value of 800 J/g which is considered to be of concern.

Interpretation of results:
GHS criteria not met
Conclusions:
After a theoretical assessment and a DSC screening test, Incozol LV is not considered to be an explosive.
Executive summary:

A theoretical assessment and a DSC screening test were conducted to evaluate the explosive properties of the test item. Incozol LV has a molecular formula C19H36N2O5. The test item contains no phosophores (bond groupings known to confer explosibility), and no auxoploses (explosion enhancing groups). (Reference: Bretherick's Handbook of Reactive Chemical Hazards -Butterworth- Heinemann 1990). The oxygen balance was calculated as -219.06 % which is below the value of -200 % which is used as a figure below which there is not considered to be an explosive hazard. In addition to the above theoretical considerations, differential scanning calorimetery (DSC) was used to look at the thermal stability of the test material up to 600 °C. The test material (1.41 mg) was placed into a sealed high pressure gold DSC pan and was subjected to a programmed temperature rise of 20 °C/min from 25 °C to 600 °C.

Additional information

Justification for classification or non-classification

Based on the structure of the molecule and the DSC screening test Incozol LV was not classified as explosive according to Regulation (EC) No 1272/2008 (CLP), as amended for the fifteenth time in Regulation (EU) 2020/1182.
