Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key data environmental classification

* Short term toxicity testing on fish: 96-h LC50/NOEC for freshwater fish: >30.85 mg/L

* Short term toxicity testing on aquatic invertebrates: 48-h EC50 for Daphnia magna: 30.85 mg/L

* Short term toxicity testing on algae: 72-h ErC50 for Raphidocelis subcapitata: 33.66 mg/L

* Effect on microorganisms: 3-h EC50 for activated sludge respiration inhibition: >1000 mg/L

Therefore, the substance is classified as Category Chronic 3 based on effect concentrations of >10 to < 100 mg/L.

Results from short-term testing of toxicity to aquatic organisms were used for PNEC derivation and classification of the substance. Testing of long-term toxicity to aquatic organisms is not indicated due to exposure considerations.
