Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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
- Study period:
- November 30, 2015
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with generally accepted scientific standards and described in sufficient detail
- Principles of method if other than guideline:
- Laser light scattering. The particle size distribution was analysed 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 analysed 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. 20.754 µm
- St. dev.:
- 0
- Remarks on result:
- other: St. Dev. not reported.
- Percentile:
- D50
- Mean:
- ca. 59.452 µm
- St. dev.:
- 0
- Remarks on result:
- other: St. Dev. not reported.
- Percentile:
- D90
- Mean:
- ca. 128.23 µm
- St. dev.:
- 0
- Remarks on result:
- other: St. Dev. not reported.
- Conclusions:
- D10 = 20.754 µm
D50 = 59.452 µm
D90 = 128.230 µm - Executive summary:

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.
