Executive summary:

The particle size of test item was determined in a study conducted according to the guidelines CIPAC MT 187 and ISO 13320 -1. Lased diffraction method was used for this purpose. Based on the findings of the study, D10, D50 and D90 for the test substance were determined to be 7.501, 156.108 and 572.166 μm, respectively. Hence, the median particle size (D50) was determined to be 156.108 μm.

Conclusion

D50: 156.108 μm
