Applicant's summary and conclusion
- Conclusions:
- From the experimental data obtained with the sieve test according to CIPAC method MT 170, it can be concluded that over 61% of the sample of Amorphophallus Campanulatus Dry Purified Extract presents a particle size greater than 0.125 mm and no sample was found under the 0.045 mm sieve after 45 minutes.
