Description of key information

The particle size distribution was determined according to CIPAC MT 187: Particle Size Analysis by Laser Diffraction and ISO 13320-1: Particle Size Analysis – Laser Diffraction Methods. The median particle size of the substance is found to be 27.007 μm. This value is considered to represent the MMAD relevant for acute inhalation toxicity.
