- Conclusions:
- The particle size distribution of test substance was determined to be MMD= 16.8 µm
- Executive summary:
In this guideline (ECB/TM February 1996) study conducted to GLP standards, the test material (EC 444-860-9) was determined to have a particle size distribution of MMD= 16.8 µm.
Reference
The test was performed with two samples of the stock dispersion and each measured in duplicate by the laser scattering / diffraction.
Description of key information
Study conducted to recognised testing guidelines with GLP.
Additional information
The measurement was performed with two samples of the stock dispersion and each measured in duplicate by the laser scattering / diffraction.
MMD= 16.8 µm
D10= 4.9 µm
D90= 25.9 µm
