Description of key information
The particle size distribution is determined with a Laser Diffraction Particle Size Analyser. The mean and median are 388.3 µm and 479.1 µm resp.
Additional information
The particle size has a mean of 388.3 µm and a median of 479.1 µm. However, it should be noted that the particle size distribution depends on the production process and could be subject to large variation.
Less than 10% of the product has a particle of 100 µm, meaning that less than 10% accounts for the inhalable fraction. Particles are irregular shaped.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
