Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Hydrolysis is expected to contribute significantly to the overall degradation of [3-(trimethoxysilyl)propyl]urea (CAS 23843-64-3) in aquatic systems. The half-life at 20-25 °C and pH 7 is 2.8 h. Due to low volatility of [3-(trimethoxysilyl)propyl]urea and its silanol hydrolysis product (2.8E-02 Pa and 4.1E-07 Pa at 25°C, respectively), the substance does not tend to enter the atmospheric compartment. Therefore, indirect photodegradation is not an important degradation pathway.
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.
