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:
- May 2018
- Reliability:
- 1 (reliable without restriction)
- 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
- Deviations:
- not specified
- GLP compliance:
- not specified
- Type of method:
- Laser scattering/diffraction
- Type of particle tested:
- primary particle
- Type of distribution:
- volumetric distribution
- Mass median aerodynamic diameter:
- >= 0.02 - <= 2 000 µm
- Key result
- Percentile:
- D50
- Mean:
- ca. 275 µm
- St. dev.:
- 10
- Conclusions:
- The particles of the test item cyclohexylamine benzoate have a median particle size D50=275 µm.
- Executive summary:
As measuring device, a Malvern Mastersizer 2000 was used. The powder was brought via a powder dispersing cell Scirocco 2000 into the laser light beam and the diffraction pattern was determined. From the diffraction pattern the particle size distribution was calculated.
The particles of the test item cyclohexylamine benzoate have a median particle size D50=275 µm.
