Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 4 mg/L based on the EC50 of 400 mg/L obtained in the activated sludge respiration inhibition test and an assessment factor of 100. 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. PNECs for sediment and soil were derived therefrom by applying the partitioning method. The substance has a low potential for bioaccumulation and this hazards for predators via the food chain are not anticipated.

Conclusion on classification

The substance was tested for three trophic levels in the aquatic environment using acute test design and the most sensitive species was Lemna gibba showing a ErC50 >100 mg/L. The substance is considered non-biodegradable, this substance will not be classified for chronic or acute aquatic toxicity hazards for CLP and DSD (regulation EC No 1272/2008 and Directive 67/548/EEC).
