Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- 1 February 2016 - 12 February 2016
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 110 (Particle Size Distribution / Fibre Length and Diameter Distributions) - Method B: Fibre Length and Diameter Distributions
- Version / remarks:
- Since the material is water soluble and of non-fibrous nature, the OECD guideline was not applicable. The magnesium methanolate samples are measured as dry powder in an aerosol beam.
- Deviations:
- yes
- Remarks:
- The magnesium methanolate samples are measured as dry powder in an aerosol beam.
- Principles of method if other than guideline:
- The magnesium methanolate samples are measured as dry powder in an aerosol beam.
- GLP compliance:
- no
- Type of method:
- Laser scattering/diffraction
- Type of particle tested:
- other: granular
- Key result
- Percentile:
- D10
- Mean:
- ca. 25.8 µm
- St. dev.:
- 1
- Key result
- Percentile:
- D50
- Mean:
- ca. 135 µm
- St. dev.:
- 1
- Key result
- Percentile:
- D90
- Mean:
- ca. 368 µm
- St. dev.:
- 1
- Conclusions:
- The range from D50 (X50) = 20 - 200 μm range is typical for magnesium methanolate.
The particle size distribution (volume distribution) of the test item was measured by laser diffraction.
The average of three measurements is:
d10: 25.8 μm
d50: 134.5 μm
d90: 368.2 μm
The sample is not at the nanoscale.

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.
