- Conclusions:
- The median particle size D50 was determined to be 233 µm.
- Executive summary:
The particle size distribution of the test item was investigated in a study conducted according to ISO 13320 (Particle size analysis - Laser diffraction methods), OECD Guideline 110 (Particle Size Distribution / Fibre Length and Diameter Distributions - Method A: Particle Size Distribution (effective hydrodynamic radius), and EPA OPPTS 830.7520 (Particle Size, Fiber Length, and Diameter Distribution) via laser diffraction. The median particle size D50 was determined to be 233 µm.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
