Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The PNEC for waste-water treatment is 32 mg/L based on the NOEC of 320 mg/L obtained in the activated sludge respiration inhibition test and an assessment factor of 10. No long-term studies on aquatic organisms are available and thus PNECs for aqueous environment were derived by the assessment method based on acute aquatic toxicity data. PNEC for sediment was derived therefrom by applying the partitioning method. PNEC for soil was derived from the acute Erathworm test in which an LC50 (14-days) was found to be greater than 1000 mg/kg and an assessment factor of 1000. The substance has a low potential for bioaccumulation and this hazards for predators via the food chain are not anticipated.
Conclusion on classification
Based on the available data on the aquatic toxicity of the substance (96h-LC50 for fish >1000 mg/L; 48h-EC50 for daphnids > 100 mg/L; 72h-EC50 for algae = 184.5 mg/L and the chronic value of the algae being the most sensitive species >10 mg/L (EC10=50.6 mg/L)), the substance has not to be classified for environmental hazard in accordance with Commission Regulation (EU) No 286/2011 of 10 March 2011 (2nd Amendment of CLP Regulation (EC) No 1272/2008).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
