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 3.7), see table below. Due to the moderately rapid hydrolysis of the registered substance, the distribution calculation is done for both the parent substance and the hydrolysis products, (3-thiocyanatopropyl)silanetriol and ethanol (CAS 64-17-5; EC No. 200-578-6).

Triethoxy(3-thiocyanatopropyl)silane (CAS 34708-08-2; EC No. 252-161 -3) is not expected to undergo any significant biodegradation and is predicted to have 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.
(3-Thiocyanatopropyl)silanetriol is predicted to have very low Henry's Law constant, 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.
