Additional information
Conclusion on classification
The results from the aquatic toxicity studies are as follows:
LC50 (96 h) fish = 11.3 mg/l (nominal concentration) with 95% confidence limits of 8 -16 mg/l.
EC50 (48 h) Daphnia = 21.1 mg/l (nominal concentration) with 95% confidence limits of 18.4 – 24.3 mg/l.
ErC50 (72 h) algae = 80.6 mg/l (nominal concentration) with 95% confidence limits 78.9-82.3 mg/l.
EC50 microorganisms was determined to be greater than 1000 mg/l.
Based on the results from the aquatic toxicity (values in the range 10 -100 mg/l) and since the substance is not readily biodegradable and has a log Pow of 4, the substance is classified as follows:
- according to Directive 67/548/EEC the substance is classified as R52/53.
- according to the CLP Regulation 1272/2008 the substance is classified as Chronic Category 3.
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.
