Description of key information

Water solubility (diphenylsilanediol): Water solubility (diphenylsilanediol): Above approximately 25 - 100 mg/l condensation reactions can occur over time limiting the concentration dissolved in water. The calculated solubility is 510 mg/l at 20°C (QSAR).

Key value for chemical safety assessment

Water solubility:
510 mg/L
at the temperature of:
20 °C

Additional information

The water solubility of the substance has been calculated using a validated QSAR method to be 510 mg/l at 20°C. The result is considered to be reliable and used as key study. The key value is supported by a measured water solubility value of approximately 400 mg/l using a preliminary/screening method in accordance with an acceptable scientific method.

The substance may undergo condensation reactions in water; these become important above approximately 25 - 100 mg/l and can limit the concentration dissolved in water. For details, see the overall physicochemical properties discussion.
