Description of key information

Long-term sediment toxicity studies are not required for Annex IX substances under REACH Regulation (EC) No 1907/2006.

Furthermore, the registered substance hydrolyses rapidly and its silanol hydrolysis product has a log D (pH 7) of -3.91 (QSAR) and a log Koc of 1.19 at pH 7 (QSAR).

Therefore, partitioning to the sediment compartment is expected to be minimal.
