Additional information
Conclusion on classification
Valid short-term toxicity studies were performed on fish, invertebrates and algae. EC50 was determined to be higher than 100 mg/L for all three trophic levels. Therefore, the substance, according to CLP criteria, does not need to be classified for acute aquatic toxicity (short-term EC50 >> 1 mg/L).
EC10 on algae after 72 hours, which can be considered a subchronic exposure time, was determined to be 89 mg/L. Taking into account this value and the short-term EC50 > 100 mg/L for all trophic levels, it can be concluded that the substance, according to CLP criteria, does not need to be classified for chronic aquatic toxicity.
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.
