EC number: 239-311-3
CAS number: 15267-95-5
48-hour EC50of > 500 mg/l, OECD 202, RL1
Measured data was not available for
(chloromethyl)triethoxysilane (CAS No. 15267-95-5) therefore read across
from the comparable substances, triethoxy(methyl)silane (CAS No.
2031-67-6) was used to fill the data gap for invertebrates.
A 48-hour EC50value of >500 mg/l
and NOEC of ≥500 mg/l have been determined for the effects of the test
substance on mobility of Daphnia magna based on nominal
concentration of the substance. The study was conducted according to a
standard guideline (EU Method C.2 (Acute Toxicity for Daphnia)
and GLP and was selected as key study (Hazleton, 1994). However, it is
likely that the test organisms were primarily exposed to the hydrolysis
products of the substance.
