Multimodal distribution with a small shoulder at 1µm and a maximum at about 15µm.

Conclusions:
The median particle size D50 of the test item deduced from the particle size distributions was 13.3 µm.
The particle size D10 of the test item deduced from the particle size distributions was 5.3 µm.
The particle size D90 of the test item deduced from the particle size distributions was 25.8 µm. Small proportion (0.5%) has a particle size diameter <= 1 µm.

Description of key information

Determination of particle size distribution by laser diffraction.Particle size distribution is multimodal with a small shoulder at 1µm, maximum at 15µm, median diameter L50=13.3µm particle size distribution is 1µm 0.5% and 10µm 32.7%.
