Method
Differential Scanning Calorimetry (DSC) according to the OECD Test Guidelines 102 and 103.
Results
During the test a loss of imbibition water was observed between 39 - 168 °C (onset at 47.2 °C, enthalpy = - 159.1 J/g), followed by an exothermic event between 304 and 422 °C (onset at 357.6 °C, enthalpy = 475.4 J/g).
Conclusion
The test item is a solid at 1013 hPa in a range of 25 °C and 304 °C.

- Laser light scattering. The test was performed according to the SOP 071 Ed.03 (Hydro 2000S-A) protocol.
The particle size distribution was analyzed using the Mastersizer 2000 tool, which uses the technique of laser diffraction to measure the size of particles. It measures the intensity of light scattered as a laser beam passes through a dispersed particulate sample. This data is then analyzed to calculate the size of the particles that created the scattering pattern. - GLP compliance:

- Conclusions:
- The test substance is a solid at 20 °C and 101325 Pa (MMD= 42.234 µm).
- Executive summary:
Method
The substance was tested for granulometry by the volumetric distribution. The particle size distribution was analyzed using the Mastersizer 2000 tool, which uses the technique of laser diffraction to measure the size of particles. It measures the intensity of light scattered as a laser beam passes through a dispersed particulate sample. This data is then analyzed to calculate the size of the particles that created the scattering pattern.
Results
MD10 = 18.375 µm
MD50 = 42.234 µm
MD90 = 82.680 µm
