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), see table below.
Table4.2.2: Distribution modelling for STP
Fraction of emission directed to air by STP (%) |
Fraction of emission directed to water by STP (%) |
Fraction of emission directed to sludge by STP (%) |
Fraction of the emission degraded in STP (%) |

Triethoxy(2,4,4-trimethylpentyl)silane is not expected to undergo any significant biodegradation beyond that of the hydrolysis product ethanol, and is predicted to have moderate Henry’s Law constant and high log Kow/log Koc. Therefore, air and sludge are the main compartments to which it is expected to partition in a sewage treatment plant, with partition to water also being significant.
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.
