Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
log Kow [3-(chlorodimethylsilyl)propyl methacrylate]: not relevant
log Kow
[3-[hydroxy(dimethyl)silyl]propyl methacrylate]: 2.6 at 20°C (QSAR)
Key value for chemical safety assessment
Additional information
The requirement to conduct an n-octanol/water partition coefficient for 3-(chlorodimethylsilyl)propyl methacrylate is waived because in contact with water, the substance hydrolyses very rapidly to form 3-[hydroxy(dimethyl)silyl]propyl methacrylate and hydrochloric acid.
The silanol hydrolysis product, 3-[hydroxy(dimethyl)silyl]propyl methacrylate has a predicted log Kow value of 2.6 at 20°C using a validated QSAR estimation method.
Log Kow is not relevant for the non-silanol hydrolysis product, hydrochloric acid, as it is inorganic.
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.
