Additional information
Conclusion on classification
Classification
The environmental classification of T000625 is derived according to the CLP Regulation (EC) 1272/2008.
No toxicity of the substance in the range of its solubility has been recorded in any of the three acute studies. In all trophic levels no toxic effects occurred up to the limit of solubility in the respective test media. In the algal growth inhibition study, the 72h-NOErC and 72h-ErC10 for algae were determined to be 0.23 and 0.42 mg/L, respectively. Additionally, the substance does not rapidly biodegrade.
Following Annex I, table 4.1.0 of the CLP Regulation, the substance is classified as Aq. Chronic 2.
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.
