Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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)
Type of information:
experimental study
Adequacy of study:
key study
Study period:
14 February - 24 June 2003
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
other: according to TNO-PML Standard Operation Procedure Q 222-W-014, 'Working with the Malvern Particle Size Analyser', Version 3
equivalent or similar to guideline
ISO 13320 (Particle size analysis - Laser diffraction methods)
Version / remarks:
November 1999
GLP compliance:
yes (incl. QA statement)
Type of method:
Laser scattering/diffraction
Type of distribution:
volumetric distribution
Key result
< 1.2 µm
Remarks on result:
other: The particle size distribution of the test substance is largely < 1.2 μm.
The test substance consists largely of agglomerates. Sonication was applied to disperse the agglomerates. This resulted in primary particles which were largely smaller than 1.2 µm, the detection limit of the analyser used. 

Description of key information

The particle size distribution of the test substance is largely < 1.2 μm (laser diffraction method).
