- Conclusions:
- The tap density of bisguanidinium phosphate was found to be 0.67 g/mL.
The particle size distribution of the test item was found to be in the range of 250 to 4000 μm. Practically no particles in the range of < 63 μm were found. - Executive summary:
Machine sieving test was carried out using the following test sieves 4, 2, 1 mm, 500, 250, 100, 63 and 45 μm according to CIPAC MT 59, 170 and 169 and based on GLP-conditions.
The particle size distribution was found to be between 250 μm and 4000 μm.
