Additional information
Aquatic toxicity (based on a read-across discussed under 6.1)
The following values have been obtained through GLP compliant studies conducted in accordance with recent guidelines. The studies were conclusive and the results are valid.
Short-term toxicity to fish: LC50(96h) > 100 mg/L, Rufli 1995
Short-term toxicity to aquatic invertebrates: EC50(48h) > 100 mg/L, Neumann 1996
Toxicity to aquatic algae and cyanobacteria: EC50(72h) = 331 mg/L, Memmert 1996
Toxicity to activated sludge: EC50(3h) > 100 mg/L, Grade 1996
One of the most conservative value LC50(96h)> 100 mg/L (fish) is carried forward for the purpose of risk assessment, classification and labelling.
Conclusion on classification
Acute aquatic toxicity
The lowest available effect level, LC50(96h) > 100 mg/L for Oncorhynchus mykiss (fish), does not trigger classification as Hazardous to the aquatic environment according to CLP Regulation (EC) No 1272/2008, Annex I, Part 4, 4.1.2.6.
The conclusion given above only takes into consideration the properties of the constituent in this mono constituent substance. As indicated in the composition under section 1.2 one of the impurities is relevant for classification and labelling of the substance. This is finally included in the Classification and Labelling section 2 where necessary based on the typical concentration value given and the harmonized classification and labelling that is available for this impurity under CLP/GHS.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
