The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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).
