chloro(methyl)silanes and tetramethylsilane and trichlorosilane from the fractionated distillation of the reaction products of silicon and chloromethane

Endpoint summary

Additional information

No data are available for the toxicity of GLS-Silane to invertebrates or algae. Reliable acute aquatic toxicity tests results are however available from a read-across substances to invertebrates (Daphnia magna) and algae (Pseudokirchnerella subcapitata). LC50 or EC50 values were >100 mg/L. A NOEC of <6.3 mg/L was determined in an algal test for trimethyloxysilane, the read-across compound for trichlorosilane. Other NOEC values were 70 mg/L for trimethylsilanol and > 118mg/L for dimethylsilanediol.

Testing for other aquatic endpoints is waived in accordance with Art. 18 REACH because the chemical is an intermediate used under strictly controlled conditions.
