Conclusion on classification
Classification
"Dangerous Substance Directive (67/548/EEC)
The available studies are considered reliable and suitable for classification purposes under 67/548/EEC. As a result the substance is considered not to be classified for acute or chronic aquatic toxicity under Directive 67/548/EEC, as amended for the 31st time in Directive 2009/2/EG."
"Classification, Labelling, and Packaging Regulation (EC) No. 1272/2008
The available experimental test data are reliable and suitable for classification purposes under Regulation 1272/2008. As a result the substance is considered not to be classified for acute or chronic aquatic toxicity under Regulation (EC) No. 1272/2008, as amended for the sixth time in Directive EC 605/2014."
Overview of results used for Classification and Labelling:
Fish, short-term/ prolonged toxicity study, freshwater: LC50 = 100 mg/L; NOEC = 100 mg/L
Daphnia magna, short-term, freshwater: EC50 = 362 mg/L
Daphnia magna, long-term, freshwater: NOEC = 55.6 mg/L
Algae (Pseudokirchneriella subcapitata), long-term, freshwater, growth rate (24 - 72h), ErC50: 9.84 mg/L and NOEC: 3.10 mg/L
Algae (Pseudokirchneriella subcapitata), long-term, freshwater, growth rate (0 - 24h), NOEC: > 1 - 10 mg/L (assumption)
