Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- 25 October 2011
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Data are sufficient and scientifically acceptable.
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Method used was laser diffraction. The technique of laser diffraction is based on the principle that particles passing through a laser beam will scatter light at an angle that is directly related to their size: large particles scatter at low angles, whereas small particles scatter at high angles. The method is standardized [ISO 13320-1: 1999 Particle size analysis - Laser diffraction methods - Part 1: General principles].
- GLP compliance:
- not specified
- Type of method:
- Laser scattering/diffraction
- Type of particle tested:
- primary particle
- Type of distribution:
- volumetric distribution
- Key result
- Percentile:
- D50
- Mean:
- >= 1 - <= 5 µm
- Remarks on result:
- other: volume median diameter
- Conclusions:
- The median particle size (x50) value is determined by customers' requirements; it is < 10 microns and the typical range is 1 to 5 microns.
- Executive summary:
The particle size distribution was analysed using laser diffraction. The method is standardized [ISO 13320-1: 1999 Particle size analysis - Laser diffraction methods - Part 1: General principles].
The median particle size (x50) value is determined by customers' requirements; it is < 10 microns and the typical range is 1 to 5 microns.
