Results and discussion

Any other information on results incl. tables

Ca. 10 % [w/w] of the test substance were found to have a diameter of > 250 µm. This fraction was separated by sieving prior to the measurement.

For the remaining fraction a median diameter of 60 µm was determined. Ca. 5 % thereof had a diameter < 10 µm.

Applicant's summary and conclusion

Conclusions:
Ca. 10 % [w/w] of the test substance were found to have a diameter of > 250 µm.
For the remaining fraction a median diameter of 60 µm was determined. Ca. 5 % thereof had a diameter < 10 µm.
