- Executive summary:
A study was conducted to determine the particle size distribution of the test item according to OECD Test Guideline 110. Laser diffraction was used for this purpose. The test item was tested as a liquid dispersion in distilled water. The particle size distribution was determined in two test series. The mean D10, D50 and D90 percentile were determined as L10= 18.4 µm, L50= 56.6 µm and L90= 148 µm, respectively.
Reference
The median particle size L50(D (v, 0.5): 50 % of particle volume or particle mass with lower particle diameter) deduced from these distributions were:
1. test series: L50= 55.340 µm
2. test series: L50= 57.959 µm
The average of the median particle size L50was:
L50= 56.6 µm (SD: 1.9)
The particle size L10(D (v, 0.1): 10 % of particle volume or particle mass with lower particle diameter) deduced from these distributions were:
1. test series: L10= 17.989 µm
2. test series: L10= 18.802 µm
The average of the particle size L10was
L10= 18.4 µm (SD: 0.6)
The particle size L90(D (v, 0.9): 90 % of particle volume or particle mass with lower particle diameter) deduced from these distributions were:
1. test series: L90= 141.845 µm
2. test series: L90= 154.468 µm
The average of the particle size L90was:
L90= 148 µm (SD: 8.9)
The particle size distribution showed a monomodal distribution.
Description of key information
The mean D10, D50 and D90 percentile were determined as L10= 18.4 µm, L50= 56.6 µm and L90= 148 µm, respectively (reference 4.5-1).
