Applicant's summary and conclusion
- Conclusions:
- The particle size distribution (granulometry) of Morin by sieve analysis method was found to be in the range of 80 micrometer to 500 micrometer. The majority of the particles were found to be more than 200 micrometer and less than 500 micrometer in size (82 %).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
