Description of key information
The experimental water solubility of Solvent Red 1 at 25°C was determined 3.3x10-4mg/l.
This value suggests that Solvent Red 1 is insoluble in water.
Key value for chemical safety assessment
- Water solubility:
- 0 mg/L
- at the temperature of:
- 25 °C
Additional information
The experimental water solubility of Solvent Red 1 at 25°C was determined 3.3x10-4mg/l.
Data from various authoritative databases also suggests that the experimental water solubility of the test chemical at 25°C is 3.3x10-4mg/l.
Thus, Solvent Red 1 can be considered to be insoluble in water.
