Key result
Operating temp.:
>= 65 - <= 90 °C
Test substance stable to sunlight:
not determined
Test substance stable to metals / metal ions:
not determined

The DSC-measurement in closed glass crucibles with the test item showed an endothermal effect in the temperature range of 65 - 90 °C. No further endothermic or exothermic effects were observed up to the final temeprature of 200 °C.

 

 

Conclusions:
The test item was considered to be thermal stable at room temperature.
Executive summary:

A study was conducted according to OECD TG 113 to determine the thermal stability of the test item using DSC measurement. The test item was weighed into a closed glass crucible under nitrogen. For the test on thermal stability, the crucibles were heated up from ambient temperature to 200 °C with a heating rate of 3 K/min. The DSC-measurement in closed glass crucibles with the test item showed an endothermal effect in the temperature range of 65 - 90 °C According to the OECD TG 113 criteria, the test item was considered to be thermal stable at room temperature as no decomposition or chemical transformation was found below 150 °C.
