Description of key information
The particle size distribution is determined with laser diffraction according to the guidelines OECD 110 (1981), ISO 13320 (2009) and EPA OCSPP 830.7520 (1996).
The following average diameters (Vol-% of particles) are determined for
D10 = 271.2 µm
D50 = 880.4 µm (median diameter)
D90= 1487.8 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.
