§ dissolved fraction of test item relating to sample size

As no significant difference was found between different amounts of surplus (sample sizes 1 g/L and 5 g/L), it can be assumed that the water solubility determined shows the saturation concentration of the test item at 20 °C and that there are no significant fractions of by-products with higher water solubilities present in the test item.

Description of key information

0.9 mg/L at 20°C

Key value for chemical safety assessment

Water solubility:
0.9 mg/L
at the temperature of:
20 °C

Additional information

The water solubility of the test item was determined via TOC measurements in the water phases of the flask method applying two different sample sizes. At 20.0 °C a solubility of 0.9 mg/L was found (BASF SE 15L00500).
