Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Hydrolysis half-life at pH 4, 7 and 9: very rapid, based on read-across substance trichloromethylsilane
Key value for chemical safety assessment
Additional information
No hydrolysis study is available for the test substance. However, a reliable study conducted according to OECD 111 is available for the related substance trichloro(methyl)silane. This substance is fully hydrolysed in less than a minute at pH 4, 7 and 9 and 1.5°C. This is also the case for other chlorosilanes for which measured data is available. Therefore, it can be concluded that the submission substance will hydrolyse rapidly under environmentally relevant conditions and no further testing is necessary.
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.
