Additional information

The key study was performed in accordance with OECD Guideline No. 105 and EC Method A6: Flask method. The test was performed with reduced shaking and equilibration periods as it is known that the functional groups within the test item structure are known to be hydrolytically unstable. The main components of the test item absorbed strongly to the HLPC column.

The liquid test item very easily dispersed in water to give a stable suspension, even though it was only shaken at a relatively slow 50 rpm which could not be cleaned up by centrifugation or filtration. Therefore, it was decided to take the result as a limit value. Furthermore, samples may have contained background extracts additional to those also in the sample blank. The final result was considered to be higher than the actual water solubility of the test item.

The water solubility of the substance is less than 4.93 mg/L at 20°C
