Description of key information

48-h EC50 >816 mg/L, D. magna, (read-across)

Key value for chemical safety assessment

Additional information

There are no data for the registered substance. However, a 48-hour EC50 value of >816 mg/l has been determined for the effects of the structurally analogous read-across substance, trimethoxypropylsilane (CAS 1067-25-0), on mobility of Daphnia magna. The result was obtained under static exposure conditions and it is likely that the test organisms were predominantly exposed to the hydrolysis products of the substance; propylsilanetriol and methanol.

An EC50 value of >100 mg/l has been obtained for propylsilanetriol using an appropriate calculation method (ECOSAR v.1.11).
