Description of key information

log Kow  [(1,1,3,3-tetramethyldisiloxane-1,3-diyl)dipropane-1,3-diyl dimethacrylate]: 8.1 at 20°C (QSAR)

log Kow [3-[hydroxy(dimethyl)silyl]propyl methacrylate]: 2.6 at 20°C (QSAR)

Key value for chemical safety assessment

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

Additional information

A predicted log Kow of 8.1 at 20°C was determined for the substance using a validated QSAR estimation method. The result is considered to be reliable.

In contact with water, the substance hydrolyses slowly to form 3-[hydroxy(dimethyl)silyl]propyl methacrylate. The silanol hydrolysis product has a predicted log Kow of 2.6 at 20°C using validated QSAR estimation method.
