Description of key information
The distribution in a sewage treatment plant (STP) has been estimated using the SimpleTreat model (implemented in EUSES 2.1.2), see table below. The distribution calculation is done for the parent substance, 4,4,7,7-tetraethoxy-3,8-dioxa-4,7-disiladecane.

4,4,7,7-tetraethoxy-3,8-dioxa-4,7-disiladecane hydrolyses moderately to 1,1,1,4,4,4-hexahydroxy-1,4-silabutane and ethanol.
Ethanol is readily biodegradable. 1,1,1,4,4,4-Hexahydroxy-1,4-silabutane 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 4,4,7,7-tetraethoxy-3,8-dioxa-4,7-disiladecane is expected to partition in a sewage treatment plant. Water is also likely to be the main compartment to which 4,4,7,7-tetraethoxy-3,8-dioxa-4,7-disiladecane will partition in the wider environment.
Additional information
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.
