Additional information
Conclusion on classification
The results from the aquatic toxicity studies are as follows:
LC50 (96 h) fish = 16 mg/L.
EC50 (48 h) Daphnia = 14.7 mg/L.
ErC50 (72 h) algae = 6.9 mg/L.
EC50 microorganisms was determined to be greater than 1000 mg/L.
Based on the results from the aquatic toxicity (lowest value 6.9 mg/L) and since the substance is inherently biodegradable and has a BCF < 500, the substance is classified as follows:
- according to Directive 67/548/EEC the substance is classified as R51/53.
- according to the CLP Regulation 1272/2008 the substance is classified as Aquatic Chronic 2 (Hazard statement: H411)
Based on the lowest L(E)C50 value (6.9 mg/L), the substance does not match the criteria for classification for acute aquatic hazard.
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.
