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.

Description of key information
