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. Due to the rapid hydrolysis of the parent substance, the distribution calculation is done for the silanol hydrolysis product

3-(Trimethoxysilyl)propiononitrile hydrolyses rapidly in contact with water to form 3-(trihydroxysilyl)propiononitrile and methanol. 3-(Trihydroxysilyl)propiononitrile is not expected to undergo any significant biodegradation, has low Henry’s Law constant and low log Kow/log Koc. Therefore, water is the main compartment to which it is expected to partition in a sewage treatment plant.
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.
