Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 16.8 mg/L based on the EC50 greater of 168 mg/L obtained in the activated sludge respiration inhibition test and an assessment factor of 100.

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 lowest short-term result from a freshwater Daphnia test that provided a 48 -h EC50 equal to 3.7 mg/L and therefore the substance is classified as acute(short term) aquatic category 2 environmental hazard according to UN-GHS.

As the most sensitive aquatic species was Daphnia (EC50: 3.7 mg/L) this endpoint has been used for the chronic aquatic classification. The substance is considered not to be rapidly degradable. The EC50 is based on is classified as an Aquatic Chronic Cat 2 according to UN-GHS.
