Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The results of the ready biodegradability study showed that methyldiacetoxyisopropoxy silane (CAS No. 329039-38-5) is only moderately biodegradable (59% biodegradation after 28 days). Considering the rapid hydrolysis of the substance in water, this biodegradation value rather accounts for the biodegradation of the transformation products. Two of the main degradation products, isopropanol and acetic acid are known to be readily biodegradable (OECD SIDS, 1997; HSDB, 2011) and therefore not persistent in the environment. Therefore, methylsilanetriol (hydrolysis product) is expected to show low to moderate potential for biodegradation.
No further data regarding biodegradation in water, sediment or soil systems are available. However, these are not part of the mandatory information requirements set in Annexes VII and VIII of Regulation (EC) No. 1907/2006.
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.
