Conclusions:
Under the conditions of the study the D10, D50, D90 and D99 of the test material was determined to be 0.441 µm, 0.654 µm, 1.182 µm and 1.949 µm, respectively.
Executive summary:

The particle size of the test material was analysed using a Laser Diffraction Particle Size Analyser (Shimadzu, SALD-2000J).

Under the conditions of the study the D10, D50, D90 and D99 of the test material was determined to be 0.441 µm, 0.654 µm, 1.182 µm and 1.949 µm, respectively.

The substance is not considered to be a nano material.
