Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The submission substance hydrolyses very rapidly (half-lives of =0.2 minutes at pH 4 and pH 9, =0.3 minutes at pH 7 and 2°C) and within the timescale of a ready biodegradation study to methanol and (poly)silicic acid with silanetriol as an intermediate hydrolysis product.
Methanol is readily biodegradable (OECD 2004).
Silanetriol and (poly)silicic acid are inorganic, therefore in accordance with Column 2 of REACH Annex VII, there is no need to conduct the ready biodegradation study.
Key value for chemical safety assessment
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
