Description of key information

Average 42.71% of all particles were sized 500 µm. 99.13% of all particles were between 180 and 710 µm. Particles above 710 nm accounted for 1.33%. Particles below 180 µm accounted for < 0.54%.  Inhalable coarse and fine particles (< 10 µm) account for < 0.06 %.

Additional information

The particle size of the substance was determined by dry sieving according to ISO 2591-1 using test sieves of woven wire cloth and perforated metal plate. OECD 110 is not applicable since the substance in soluble in water above 10 g/L at ambient temperature.
