Details on results:

The water solubility of the test substance at room temperature was estimated to be < 1 g/L by visual judgement in the preliminary test. The saturation concentration of the test substance was analytically estimated by a simplified flask method in the preliminary test at 20 °C to be in the range of the quantification limit for the DOC-measurements (1 mg DOC/L).

Conclusions:

Interpretation of results: slightly soluble (0.1-100 mg/L)
The water solubility of the test substance was estimated to be in the range of 1 mg/L (quantification limit of the DOC measurements) at 20 °C +/- 1 °C. Thus, the test substance was considered to be slightly soluble or insoluble.

Executive summary:

The water solubility of the test substance was determined according to EU method A.6, OECD Guideline 105, and EPA OPPTS 830.7840, EPA OPPTS 830.7860 guideline and DIN EN 1484 guideline. Because of the low solubility of the test substance in water and the low sensitivity of the analytical method available the experimental determination of the water solubility of the test substance was technically not feasible.

Therefore, the water solubility of the test substance was estimated to be in the range of 1 mg/L (quantification limit of the DOC measurements) at 20 °C +/- 1 °C. Thus, the test substance was considered to be slightly soluble or insoluble.
