Description of key information

Log Kow (substance): Not relevant
Log Kow (Silanol Hydrolysis product): -0.02 at 20°C (OECD 107)

Key value for chemical safety assessment

at the temperature of:
20 °C

Additional information

The requirement to test the substance for n-octanol-water partition coefficient is waived becasue in contact with water the substance hydolyses rapidly to form phenylsilanetriol and hydrogen chloride. A Log Kow value of -0.02 has been determined for the silanol hydrolysis product, phenysilanetriol in a guideline study according to GLP.
