Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Low potential for adsorption. Log Koc for silanol hydrolysis product = 1.8 (predicted).
Key value for chemical safety assessment
Additional information
The substance hydrolyses very rapidly to substances which have low log Kowvalues (<3) and thus have low potential for adsorption.
For environmental exposure assessment, adsorption is predicted using the ‘non-hydrophobics’ log Kow-based prediction method for log Kocdeveloped by Sabljić and Güsten (1995) for the European Commission, and recommended in EU Guidance.
The relevant equation is:
Log Koc= 0.52 log Kow+ 1.02
Therefore, log Kocfor silanol hydrolysis product = 1.8.
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.
