Reference
Preliminary estimation
| Mass of sample (mg) | Volume of water in which sample dissolves (ml) | Estimated solubility (g/L) |
| 1000 | 1 | >1000 |
Description of key information
In a GLP-compliant study according to a preliminary test as specified in test method EU A.6, the sample was completely miscible with water with an estimated solubility of >1000 g/L at 20°C; therefore, no further testing was required (K1; Younis, 2017).
Key value for chemical safety assessment
- Water solubility:
- 1 000 g/L
- at the temperature of:
- 20 °C
Additional information
The sample is completely miscible with water with an estimated solubility of >1000 g/L at 20°C
