Overall concentration:         ≤ 2.13 x 10^-5 g/L at 20.0 ± 0.5 ºC

Conclusions:
Interpretation of results (migrated information): insoluble (< 0.1 mg/L).
Under the conditions of the study, the water solubility of the test material was determined to be less than or equal to 2.13 x 10^-5 g/L at 20.0 ± 0.5 °C. This result classifies the test material as insoluble.
Executive summary:

The water solubility of the test material was determined in accordance with the standardised guidelines EU Method A.6 and OECD 105 using the shake flask method. Under the conditions of the study, the water solubility of the test material was determined to be less than or equal to 2.13 x 10^-5 g/L at 20.0 ± 0.5 °C. This result classifies the test material as insoluble.
