Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Study reports have been available for consideration in respect of acute tests with fish, invertebrates, algae, micro-organism and daphnia reproduction test.

A PNECaquatic of 0.016 mg/l has been derived from 0.8 mg/l (21 d-NOEC) for effects on Daphnia reproduction test (the lowest long-term NOEC for two long-term results from species representing two trophic levels (Daphnia and algae)) by an assessment factor of 50.

No measured data are currently available for marine organisms therefore the marine PNEC is derived from data obtained for freshwater species (21 d-NOEC=0.8 mg/l), applying an assessment factor of 500 to give PNECseawater = 0.0016 mg/l.

The intermittent releases PNEC is derived from lowest value obtained for freshwater species (EC50 = 100 mg/l), applying an assessment factor of 100 to give PNECwater,intermittent = 1 mg/l.

The PNEC for waste-water treatment is 10 mg/l based on the EC50 of 100 mg/l and an assessment factor of 10.

PNECs for sediment, marine sediment and soil have been derived using the partitioning method.

Below table is the summary of the value of PNEC in each compartment.

Conclusion on classification

From the available information, the lowest short-term EC/L50 from each of three trophic levels (fish, Daphnia and algae) was above 100 mg/l. Therefore, it is not classified for acute aquatic toxicity according to CLP (Regulation (EC) No 1272/2008) or DSD (Directive 67/548/EEC).

While its classified as Chronic Aquatic Toxicity Cat. 3 (H412: Harmful to aquatic life with long lasting effects). EU ECHA ATP11 harmonized classification is approved as Chronic Aquatic Toxicity Cat. 3

The substance is classified as R52/53 due to the effects seen with Scenedesmus subspicatus (EC50 of 89.9 mg/l) and the lack of biodegradability.
