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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 based on low log Kow values (< 3)
For environmental exposure assessment: methylsilanetriol Log Koc = -0.23 (TGD, non-hydrophobics log Kow prediction method)
Key value for chemical safety assessment
- Koc at 20 °C:
- 0.589
Additional information
The parent substance Dimethoxymethylsilane (CAS 16881 -77-9) and its hydrolysis products have low log Kow values (<3) and thus have low potential for adsorption. Therefore, in accordance with Column 2 of REACH Annex VIII, the adsorption/desorption screening test does not need to be conducted, and also there is no need for further information on adsorption/desorption.
For the environmental exposure assessment, adsorption has been estimated based on the log Kow using the TGD (Technical Guidance Document) non-hydrophobics equation. The log Koc of the silanol hydrolysis product was calculated to be -0.23.
[LogKoc: -0.23]
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.
