Applicant's summary and conclusion
- Conclusions:
- Majority of the particles were found to be in the size 150 (28.16%) - 850 (24.73%) micrometer in size.
- Executive summary:
The particle size distribution (granulometry) of 5-hydroxyisopthalic acid by the sieve analysis method was found to be in the range of 75 micrometer to 850 micrometer. Majority of the particles were found to be in the size 150 (28.16%) - 850 (24.73%) micrometer in size.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
