Particle size distribution (Granulometry)
Administrative data
Link to relevant study record(s)
- Endpoint:
- particle size distribution (granulometry)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with generally accepted scientific standards and described in sufficient detail
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Laser light scattering. The test was performed according to the SOP - STR 071 Ed. 01 (Hydro 2000S-A) protocol.
The particle size distribution was analyzed using the Mastersizer 2000 tool, which uses the technique of laser diffraction to measure the size of particles. It measures the intensity of light scattered as a laser beam passes through a dispersed particulate sample. This data is then analyzed to calculate the size of the particles that created the scattering pattern. - GLP compliance:
- no
- Type of method:
- Laser scattering/diffraction
- Type of distribution:
- volumetric distribution
- Percentile:
- D10
- Mean:
- ca. 4.452 µm
- St. dev.:
- 0

- Conclusions:
- The test was performed according to the SOP - STR 071 Ed. 01 (Hydro 2000S-A) protocol. Results are reported below:

Methods
The substance has been tested for granulometry by the volumetric distribution.
The particle size distribution was analyzed using the Mastersizer 2000 tool, which uses the technique of laser diffraction to measure the size of particles. It measures the intensity of light scattered as a laser beam passes through a dispersed particulate sample. This data is then analyzed to calculate the size of the particles that created the scattering pattern.
Results
D10 = 4.452 µm
D50 = 13.788 µm
D90 = 31.212 µm
Reference
The analysis has been run after 2 minutes of sonification.

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.
