Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Log Kow of the substance: -2.3
Log Kow of the silanol hydrolysis products: -2.95
Log Kow of the amino alcohol hydrolysis product: -2.5

Key value for chemical safety assessment

Log Kow (Log Pow):
-2.3
at the temperature of:
25 °C

Additional information

The low solubility of the substance in water and octanol and its instability and possible forming of condensation products in water makes measurement of the octanol-water partition coefficient difficult. The Log Kow of the substance and its silanol hydrolysis product have been estimated using appropriate QSAR methods.
