Additional information
Conclusion on classification
The substance has reliable short-term E(L)C50 values of >100 mg/l in fish, 314 mg/l in invertebrates and 611 mg/l in algae. It has reliable ErC10 and NOEC values of 136 and 75 mg/l in algae. It has a reliable long-term NOEC of 28 mg/l in Daphnia, based on read-across from a structural analogue.
The substance hydrolyses very rapidly in water (half-life 61.5 min at pH 7 and 25°C), and the silanol hydrolysis product, vinylsilanetriol, is not readily biodegradable but has a log Kow <3. The non-silanol hydrolysis product, 2 -methoxyethanol, is readily biodegradable.
These data are consistent with the following classification under Regulation (EC) No 1272/2008 (as amended) (CLP):
Acute toxicity: Not classified.
Chronic toxicity: Not classified.
