- Executive summary:
A study was conducted to determine the water solubility of the test substance according to EU Method A.6 and OECD Guideline 105. The water solubility was determined by the flask method. The test substance was miscible with water in any proportion. With increasing amount of test substance a gel was formed. Under the study conditions, the water solubility of the test substance at 20°C was >740 g/L (Frischmann, 2013).
Reference
When 14.6 g of test substance was mixed with 5 mL of water, a gel with a total weight of approximately 19.6 g was formed. This was equivalent to 74% (w/w) of test substance in solution/gel. As the density of the water would significantly increase with addition of the test substance, it could be concluded that water solubility was about 740 g/L, resulting in a gel.
Due to the fact , that the formation of the gel is a continuous process and no discrete point could be identified at which dissolution in water switches to gelling, the water solubility could be approximated at >740 g/L.
Description of key information
The water solubility was determined according to OECD Guideline 105 and EU Method A.6 (Frischmann, 2013).
Key value for chemical safety assessment
- Water solubility:
- 740 g/L
- at the temperature of:
- 20 °C
