Description of key information
Additional information
The distribution in a sewage treatment plant (STP) has been estimated using the SimpleTreat model (implemented in EUSES 2.1.2/Chesar 3.5), see table below. Although, the submission substance hydrolyses rapidly in contact with water, the distribution calculation is done for all assessment entities.

Tris(2-methoxyethoxy)vinylsilane hydrolyses rapidly to form vinylsilanetriol and 2-methoxyethanol. 2-Methoxyethanol is readily biodegradable. Vinylsilanetriol is not expected to undergo any significant biodegradation, and is predicted to have low Henry’s Law constant and low log Kow/log Koc. Distribution modelling for STP indicates that water is the main compartment to which it is expected to partition in a sewage treatment plant. Water is also likely to be the main compartment to which vinylsilanetriol will partition in the wider environment.
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.
