Description of key information

Water solubility (substance): 0.85 g/l at 20°C 
Water solubility (hydrolysis product): 1,000,000 mg/L at 20°C

Key value for chemical safety assessment

Water solubility:
0.85 g/L
at the temperature of:
20 °C

Additional information

The water solubilities for the test substance ranging from 0.86 to 0.83 g/L at 19.5°C; the mean value is 0.85 g/L at 20°C and this value will be used for risk assessment. These results were obtained using an appropriate EU test method and therefore are considered to be reliable and assigned as key study. The water solubility of the silanol hydrolysis product has been calculated using an appropriate predictive method.
