The particle size distribution showed a bimodal distribution with maxima at approx. 1 µm and approx. 9 µm, respectively.

Conclusions:
The median particle size L50 of the test item deduced from the particle size distributions was 6.9 µm.
The partcile size L10 of the test item deduced from the particle size distributions was 0.8 µm.
The particle size L90 of the test item deduced from the particle size distributions was 23.0 µm.

Description of key information

L50 = 6.9 μm

Additional information

The particle size distributions of the test item was determined by laser diffraction (light scattering) according to OECD guideline 110.

The median particle size L50 of the test item deduced from the particle size distributions was 6.9 µm.

The partcile size L10 of the test item deduced from the particle size distributions was 0.8 µm.

The particle size L90 of the test item deduced from the particle size distributions was 23.0 µm.
