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 3.4), see table below. Due to the rapid hydrolysis of the registered substance, the distribution calculation is done for the hydrolysis products, [3-(2,3-epoxypropoxy)propyl]silanetriol and methanol.

[3-(2,3-Epoxypropoxy)propyl]silanetriol 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 [3-(2,3-epoxypropoxy)propyl]silanetriol 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.
