Specific details on test material used for the study:
Batch number: 3210640070
Key result
Water solubility:
ca. 10 g/L
Conc. based on:
test mat.
Temp.:
20 °C
Remarks on result:
other: The test material is completely soluble (100%) at 10 g/L.
Water solubility:
ca. 100 g/L
Conc. based on:
test mat.
Temp.:
20 °C
Remarks on result:
other: The test material has found to be 99.4% soluble at about 100 g/L.
Water solubility:
ca. 300 g/L
Conc. based on:
test mat.
Temp.:
20 °C
Remarks on result:
other: The test material has found to be 85% soluble at about 300 g/L.

Conclusions:
The test material is completely soluble up to 0.01 g/mL. Increasing the amount of test matrial in water, the solubility varies: about 15% of test material appears to be almost insoluble at 0.3 g/mL.
Executive summary:

The test method OECD 105 was used to perform the analysis using a modified version of flask method indicated in OECD 105 in order to check the extent of the solubility of the whole test material. In particular, test material amounts were weighted in 10 mL of water; the solution was shaken, then it was filtered on a buckner filter and residue of unsoluble part was put in an oven in order to check the weigth. The test material is completely soluble up to 0.01 g/mL. Increasing the amount of test item in water, solubility varies: about 15% of test item appears to be almost insoluble at 0.3 g/mL.

Description of key information
