Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Acute hazard category

There are adequate short-term studies available covering three trophic levels, i.e. algae, daphnia and fish. According to Regulation (EC) No 2008/1272, the submission substance does not need to be classified for aquatic acute hazards, because available EC50 values are > 1 mg/L, i.e. the most sensitive EC50 value is 48h-EC50 (Daphnia magna, immobilisation) = 1.05 mg/L.

 

Chronic hazard category

There is one adequate long-term toxicity effect concentration available, i.e. for algae. The derived effect concentration is 72h-NOEC (Selenastrum capricornutum, growth rate) = 0.66 mg/L. The submission substance is not rapidly biodegradable. Following the classification system of Regulation (EC) No 2008/1272, the submission substance must be classified for aquatic hazard category chronic 2, based on both acute derived effect concentrations and chronic effect concentrations (i.e. 1 mg/L < EC50 < 10 mg/L, 0.1 mg/L < NOEC < 1 mg/L, not rapidly biodegradable).

In conclusion, the submission substance is classified for aquatic hazard Category Chronic 2, 'toxic to aquatic life with long-lasting effects' (H411).
