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:
- 21 JUL 2020 to 14 AUG 2020
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- ISO 13320 (Particle size analysis - Laser diffraction methods)
- Deviations:
- not applicable
- GLP compliance:
- no
- Type of method:
- Laser scattering/diffraction
- Type of particle tested:
- primary particle
- Type of distribution:
- volumetric distribution
- Percentile:
- D10
- Mean:
- ca. 17 - ca. 23.2 µm
- Remarks on result:
- other: not more information available
- Percentile:
- D50
- Mean:
- ca. 50.6 - ca. 60.5 µm
- Remarks on result:
- other: not more information available
- Percentile:
- D90
- Mean:
- ca. 103 - ca. 123 µm
- Remarks on result:
- other: not more information available
- Conclusions:
- The particles have a size for d10 with 17-23.2 µm, for d50 with 50.6-60.5 µm and for d90 with 103-123 µm.
- Executive summary:
The particle size distribution of the test item was assessed by the sponsor in an in-house non-GLP test via laser diffraction with a Malvern device. The procedure is similar to ISO 13320. It was observed, that the particles have the following sizes and are not existing as nanomaterial:
d10: 17-23.2 µm
d50: 50.6-60.5 µm
d90: 103-123 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.
