Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

- 69 mg/L
- EC10 or NOEC for freshwater algae:
- 10 mg/L
Additional information
The influence of the reaction mass containing six benzylated amine silanes on the growth of the green algal species Scenedesmus subspicatus was investigated in a 72-hour static test according to the OECD guideline 201 and GLP (2004). The nominal test concentrations used were 0.32, 1.0, 3.2, 10, 32 and 100 mg/L and a control. A 72-hour EC50 of 69 mg/L and a NOEC of approximately 10 mg/L (nominal) were determined for reaction mass containing six benzylated amine silanes on growth rate of Scenedesmus subspicatus. Since the substance degrades fast to its hydrolysis products, it is very likely that the test organisms were exposed to both the parent substance and its hydrolysis products.
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.
