Description of key information
Additional information
The study was carried out with two replicates, using a sieving methodology. Samples (10.010 g for replicate 1 and 10.012 g for replicate 2) of the test item were transferred to a sieve system (after removal of fine powder), where the particles encountered a series of 4 sieves with decreasing mesh sizes. The mesh sizes of the sieves were 18, 35, 60, 140 mesh and container. After shaking for 20 minutes, the particles retained in each of the sieves were collected, and weighed. These data were used to determine the granulometric distribution of the substance, expressed as a particle size distribution by mass.

The quantity of fine powder (< 0.053 mm) removed from the sample before final sieving was equivalent to 96%.
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.
