Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

EC50 (48h) in aquatic invertebrates (Daphnia magna) = 48.9 mg/l.

ErC50 (7d) in aquatic plants (Lemna minor) = 50.3 mg/l.

Additional information

Justification for classification or non-classification

According to the CLP Regulation (EC 1272/2008), the threshold of classification of a substance for acute aquatic toxicity is 1 mg/l. This limit is compared with LC50 (96h) for fish, EC50 (48 h) for daphnia and EC50 (72 - 96 h) for algae or aquatic plants.

Available 48-hour test on fish could not be assessed due to the lack of details. Therefore, the classification process relied on data of toxicity to aquatic invertebrates and plants.

Toxicity on daphnia was assessed in a 48-hour study and acute immobilisation was seen in 50 % of daphnia exposed at concentration of 48.9 mg/l.

Toxicity on lemna was assessed in 7-day test and effects on growth rate of fronds and dry weight were reported with ErC50 = 50.3 mg/l and ErC50 = 251 mg/l, respectively.

No chronic toxicity data is available from long-term studies. In case of lack of chronic data, the potential for chronic toxicity is identified by appropriate combinations of acute toxicity data and lack of biodegradability. The threshold of classification is 100 mg/l.

Based on the results obtained with daphnia and lemna, classification for chronic aquatic toxicity was applied according to the CLP Regulation (EC 1272/2008).
