Description of key information

Average particle size of the test substance = 39.609 µm (D10 = 2.119 µm, D50 = 15.735 µm, D90 = 107.745 µm) [by laser diffraction (dry method), no guideline followed]
According to the results, the inhalation of particles has to be regarded:
- ~ 89% are <100 µm (inhalable fraction)
- ~ 40% are <10 µm (thoracic fraction)
- ~19% are < 4µm (respirable fraction)
