Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Once released into the aquatic compartment, methyldiacetoxyisopropoxy silane (CAS No. 329039-38-5) will hydrolyze rapidly (DT50 < 4 h) mainly into methylsilanetriol, acetic acid and isopropanol. Based on the log Pow values of methyldiacetoxyisopropoxy silane and degradation products, all below 3, a low potential for adsorption to soil and sediment particles is expected. In view of its vapour pressure value (199 Pa), this substance can be considered as volatile. Nevertheless, due to its susceptibility to undergo indirect photodegradation (by reaction with OH-radicals) in air, accumulation in air and transport through the atmosphere into other environmental compartments is not expected to occur to a significant degree (DT50= 31 h).
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.
