Additional information
Conclusion on classification
There was a moderate toxicity to aquatic organisms observed in short term tests with fish, daphnia and algae. The toxicity (EC50) was in the range of 10 to 100 mg/L, the log Pow is 2.3 and the substance is not readily biodegradable. The EC10(72h) for algae was determined to be 1.4 mg/L. These data are reliable and conclusive. No further data on chronic aquatic toxicity studies and for the evidence of rapid degradation are available.
The criteria for classification for hazards to the aquatic environment according to Regulation (EC) No 1272/2008 are fulfilled. Accordingly, the substance is to be classified as Aquatic Chronic 3 "Harmful to aquatic life with long lasting effect" (H412).
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
