Description of key information

The substance contains approximately 100 % of particles with a particle size smaller than 3.4 mm, and approximately 4 % of particles are smaller than 1 mm (only 0.07% < 500 µm).

Additional information

The particle size distribution was determined by a sieving method: bead distribution test for amides.
