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

Additional information

Data for short-term toxicity to fish, Daphnia and algae have been read-across from the structurally similar substances trimethylsilanol (CAS 1066-40-6), in which the vinyl group (-CH=CH2) is replaced by a methyl group (-CH3), and trimethoxy(vinyl)silane (CAS 2768-02-7), which contains the vinyl group and three methoxy groups. The L(E)C50 results for fish, Daphnia and algae are 271 mg/l, 124 mg/l and >684 mg/l respectively. These data suggest that the most susceptible trophic level is aquatic invertebrates.

Data waivers are applicable to long-term aquatic toxicity data.

A 3hr ASRI EC10 value of >100 mg/l (loading rate) (OECD 209) has been read across from a structurally-related substance for the toxicity to microorganisms endpoint.
