Description of key information

The octanol solubility of C.I. Direct Blue 264 was determined at 20 °C using HPLC-analysis. 500 mg/mL and 5000 mg/mL concentrations of C.I. Direct Blue 264  were prepared and stirred at 20 °C. After 34 days of stirring, the saturation equilibrium was still not reached. 
As a conclusion the solubility of C.I. Direct Blue 264 is depending on time and on the initial weight. Therefore a solubility range of 23-191 mg/L can be concluded.

Key value for chemical safety assessment

Solubility in organic solvents at 20°C:
191 mg/L
