Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

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.

Additional information

Conclusion on classification

The results from aquatic toxicity studies are as follow:

- Short-term toxicity to fish. Key study: LC50 (96h) = 1011.11 mg/L (based on mortality) (read-across from supporting substance butanone oxime).

- Long-term toxicity to fish. Key study: LC50 (14d) > 119.94 mg/L (based on mortality) and NOEC (14d) = 59.97 mg/L (read-across from supporting substance butanone oxime).

- Short-term toxicity to aquatic invertebrates: Key study: EC50 (48h) = 241.08 mg/L (based on mobility) (read-across from supporting substance butanone oxime).

- Long-term toxicity to aquatic invertebrates: Key study: LC50 (21d) > 119.94 mg/L (based on parental mortality), EC50 (21d) > 119.94 mg/L (based on reproduction) and NOEC (21d) >= 119.94 mg/L (based on reproduction) (read-across from supporting substance butanone oxime).

- Toxicity to aquatic algae: Key study: EC50 (72h) = 19.19 mg/L and NOEC (72h) = 3.12 mg/L (based on growth rate) (read-across from analogue substance butanone oxime)

Based on the results from the aquatic toxicity tests, the substance the substance butan-2-one O,O',O''-(vinylsilanetriyl)oxime is not classified for aquatic toxicity according to CLP Regulation (EC) No. 1272/2008.
