- Conclusions:
- The particle size distribution of test substance was measured to be MMD=16.7 µm
- Executive summary:
In this EC guideline study conducted to GLP standards, the test material (EC 438-340-0) was determined to have a particle size distribution of MMD=16.7 µm.
Reference
A solubility test showed, that the test item is both: sparingly soluble and well dispersible in water containing 0.2 g/l sympatens SHO/400. For the particle size distribution measurement the test item was dispersed two times in pre-saturated water
The particle size distribution was found to range from
approximately 0.3 µm to 100 µm.
The mass median diameter was determined to be 16.7 µm.
Description of key information
Study conducted to recognised testing guidelines with GLP.
Additional information
MMD= 16.7µm
D10= 1.5µm
D90= 40µm
Particle size distribution ranges from approx. 0.3 to 100µm.
