Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusion on classification

The results from aquatic toxicity studies are as follow:

- Short-term toxicity to fish. Key study: LC50 (96h) = 696.76 mg/L (basis for effect: mortality) (read-across from the analogue substance acetone oxime).

- Short-term toxicity to aquatic invertebrates: Key study: EC50 (48h) = 678.76 mg/L (basis for effect: mobility) (read-across from the analogue substance acetone oxime)

- Toxicity to aquatic algae: Key study: EC50 (72h) = 315.36 mg/L and NOEC (72h) = 62.34 mg/L (basis for effect: growth rate) (read-across from the analogue substance acetone oxime).

- Toxicity to microorganisms:Key study: EC50 (3h) > 239.78 mg/L (activated sludge, basis for effect: respiration rate) (read-across from the analogue substance Wasox-VMAC2).Key study: EC50 (3h) > 248.06 mg/L (activated sludge, basis for effect: respiration rate) (read-across from the analogue substance Wasox-MMAC2).

Based on the results from the aquatic toxicity tests, the substance the substance EAC3 is not classified for aquatic toxicity according to CLP Regulation (EC) No. 1272/2008.
