Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Bioaccumulation: aquatic/sediment: Low potential for bioaccumulation

Key value for chemical safety assessment

Additional information

The substance hydrolyses very rapidly (half-life 11.3 minutes at pH 7 and 25°C) to form dimethylsilanol. Dimethylsilanol has a low log Kow value (0.6) and thus has a low potential for bioaccumulation. The ultimate hydrolysis product dimethylsilanediol also has a low log Kow (-0.38); therefore, in accordance with Column 2 of REACH Annex IX, the bioaccumulation in aquatic species study does not need to be conducted.
