- Conclusions:
- The median particle size D50 of the test item propyl gallate is 232 μm.
- Executive summary:
The particle size distribution of the test item is:
D10: 31.6 µm
D50: 232 µm
D90: 507 µm
Reference
From this pattern the particle size distribution of the test item was calculated by using characteristic values:
D10: 10 Vol.-% of the particles have a smaller diameter than 31.6 µm
D50: 50 Vol.-% of the particles have a smaller diameter than 232 µm
D90: 90 Vol.-% of the particles have a smaller diameter than 507 µm
Description of key information
The particle size distribution of the test item is:
D10: 31.6 µm
D50: 232 µm
D90: 507 µm
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
