Description of key information
The particle size determination is done by means of laser diffraction analysis.
The mass median diameter of the particles determined by laser diffraction analysis is 427,7 μm.
Additional information
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.
