D90 = 106.783 µm - Executive summary:
Method:
Particle size distribution was analysed using the Mastersizer 2000 tool. Particles size was measured by the laser diffraction technique, which measures the intensity of light scattered as a laser beam passes through a dispersed particulate sample. This data is then analysed to calculate the size of the particles that created the scattering pattern.
Result:
Analysis carried out after 2 minutes of ultrasonic treatment:
D10 = 5.514 µm
D50 = 35.807 µm
D90 = 106.783 µm

Additional information
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.
