- Type of method:
- sieving
- Type of particle tested:
- primary particle
- Type of distribution:
- mass based distribution
- Remarks on result:
- not determinable because of methodological limitations
- Conclusions:
- Determination of the particel size was not possible. Sieving these globes immediately leads to destruction of the globes forming a hygroscopic solid but again no dusty matter could be observed. A continuation of the sieving was therefore not possible and the determination was aborted.
- Executive summary:
The determination of particle size was performed in a GLP-study using a dry sieve technique according to DIN ISO 4497 and a laser diffraction method (OECD 110).
The sample consisted of small hard globes which are easily pourable. Shaking these pellets in the original glass bottles does not destroy the globes and no particulate matter is virtually detectable in the original bottle. However,
sieving these globes immediately leads to destruction of the globes forming a hygroscopic solid but again no dusty matter could be observed. A continuation of the sieving was therefore not possible and the determination was aborted. The determination of the particle size distribution by laser diffraction was not performed in this study.

Description of key information
Dry sieve tests were performed in GLP-studies according DIN ISO 4497 using two sieves with a mesh size of 1 mm and 100 µm respectively of samples of different suppliers. The particle size in any case show that most of the particles have sizes bigger than 1 mm (< 90 %). The amount smaller than 100 µm was for each sample very low (> 0.01 %).
In one case the particle size distribution could not be done because sieving these globes immediately leads to destruction of the globes forming a hygroscopic solid but again no dusty matter could be observed.
