Description of key information

Log Kow (substance): 0.5 (QSAR)
Log Kow (silanol hydrolysis product): -2.6 (QSAR)

Key value for chemical safety assessment

Log Kow (Log Pow):
at the temperature of:
20 °C

Additional information

The requirement to test the substance for octanol-water partition coefficient is waived because in contact with water the substance very rapidly hydrolyses to form [3-(2,3-epoxypropoxy)propyl]silanetriol. The Log Kow of both the substance and the silanol hydrolysis product have been calculated using validated QSAR methods.
