Pre-testing
| weight of test item [mg] | volume of water added [mL] | sample size [mg/L] | observation |
| 101.27 | 10 | 10127 |
undissolved after rolling overnight; test item floats as a drop on the surface |
| 109.79 | 100 | 1097.9 | undissolved after rolling overnight; test item floats as a drop on the surface |
| 21.63 | 200 | 108.15 | undissolved after rolling overnight; test item floats as a drop on the surface |
| 9.35 | 1000 | 9.35 | undissolved after rolling overnight; test item floats as a drop on the surface |
The water solubility was estimated to be < 9.35 mg/L.
TOC
The carbon content of test item was determined to 76.09 g/100g
| corresponding dissolved test item [mg/L] # | dissolved fraction [%] § | |
Mean value of single values for sample size 1 g/L |
0.86 ± 0.13 | 0.08 |
| Mean value of single value for sample size 5 g/L | 0.86±0.11 | 0.02 |
| Mean value of single values (1g/L and 5g/L) | 0.86±0.11 |
# calculated from the TOC of the test solutions and the content of C of the test item
§ 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).
