Description of key information

The water solubility of the test material was determined to be <0.005 mg/L at 20 °C in the key study.

Key value for chemical safety assessment

Additional information

The water solubility of the test material has been addressed by providing a key study in the form of a test report (Wenighofer and Fröschl, 2012) that was assigned a reliability score of 1, using the principles set out in Klimisch (1997). The water solubility was investigated in accordance with the standardised guidelines OECD 105 and EU Method A.6 using the flask shaking method.

Under the conditions of this study, the test material was found to have a water solubility of <0.005 mg/L in purified water at both 10 and 20 °C. It can therefore be described as insoluble.

 

Supporting information is provided in the form of a company report (Sunderkötter, 2012) that was assigned a reliability score of 2, using the principles set out in Klimisch (1997). The water solubility was investigated in accordance with the standardised guidelines OECD 105 and EU Method A.6. The mean solubility in water at 30.0 °C (loading rate 20 g/L, pH 6.2 – 6.6) is < 1 mg/L.

 

Further supporting information is provided in the form of handbook data. All three sources are peer reviewed data that, as such, can be awarded a reliability score of 2 in accordance with the criteria detailed in Klimisch (1997). 

Kirk (1997), Clayton (1981) and O’Neil (2006) all quoted the test material as being insoluble. No specific value for the solubility was provided and methods of determination are not included in handbook data.
