- Conclusions:
- The mass median diameter of FAT 40224/C is 13.1 µm.
- Executive summary:
In a GLP-compliant study with FAT 40224/C, the mass median diameter of the test substance was determined according to OECD guideline 110. The test was performed on a CILAS Granulometer Model 715 and the technique is based on the principle of light diffraction. The mass median diameter of the test substance was determined to be 13.1 µm.
