Description of key information

Log Kow (tris(2-methoxyethoxy)vinylsilane): 0.3 at 20°C (QSAR)
Log Kow (vinylsilanetriol): -2.0 at 20°C (QSAR)
Log Kow (2-methoxyethanol): -0.77

Key value for chemical safety assessment

Additional information

No measured data are available for the partition coefficient of the substance and therefore a partition coefficient of 0.3 has been calculated using a validated QSAR. The substance hydrolyses rapidly in contact with water and, therefore, the partition coefficient of the silanol hydrolysis product has been calculated as -2.0. These results are considered reliable. The partition coefficient of the hydrolysis product 2 -methoxyethanol is reported in a secondary source as -0.77.
