- Conclusions:
- The particle size distribution of the substance was determined using laser diffractioni methods according to ISO 13320: 2009.
Particle size distribution of the substance: D10= 1.23 µm, D50= 16.1 µm and D90= 161 µm.
The particle size distribution range of the sample is 0.113 µm- 859 µm.

Description of key information
Particles is dispersed by Nitrogen (dry dispersion), tested by high precision potical sensor under specific wavelength (632.8 nm) of He-Ne laser light source, according to laser diffraction and scattering theory (Mie theory). And the particle size distribution of the substance was determined using laser diffractioni methods in a GLP study according to ISO 13320: 2009.
Particle size distribution of the substance: D10= 1.23 µm, D50= 16.1 µm and D90= 161 µm.
The particle size distribution range of the sample is 0.113 µm- 859 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.
