Applicant's summary and conclusion

Conclusions:
The results of the laser diffraction test conducted to determine the particle size of 3,4,5- Trimethoxycinnamic Acid are summarised below. The analysis was conducted using the small volume (wet) module (SVM) with water as the dispersant.

Volume weighted mean: 209 µm
Mode 418 µm
MMAD (mass median aerodynamic diameter) 118 µm
d10 - 10 % of material is < 11.2 µm
d50 - 50 % of material is < 112 µm
d90 - 90 % of material is < 560 µm
volume of sample < 10.00 μm 9.00 %
