Reference
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

Percentile:
D90
Mean:
ca. 368 µm
St. dev.:

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.
