Description of key information

The test item has a median particle size D50 = 41.7 µm, which was determined by laser diffraction measurement according to OECD Guideline 110 (1981), OPPTS 830.7520 (1996) and ISO 13320 (2009). The D10 and the D90 were found to be 6.5 µm and 185.8 µm, respectively, and the volume weighted mean was 107.719 µm.
