Conclusion on classification
According to Regulation (EC) No.1272/2008 and amendments (CLP), the criteria for classification of a substance in category Acute 1 are defined on the basis of acute aquatic toxicity data only (EC50, EL50, LC50 or LL50); classification is required for values ≤ 1 mg/L. However according to Table 4.1.0 (Commission Regulation (EU) No 286/2011 of 10 March 2011), Classification categories for hazardous to the aquatic environment, (iii) Substances for which adequate chronic toxicity data are not available, and the substance is not rapidly degradable and/or the experimentally determined BCF ≥ 500 (or, if absent, the log K ow ≥ 4), classification as Category Chronic 2 is required if the following short-term results are obtained:
96 hr LC 50 (for fish) > 1 to ≤10 mg/l and/or
48 hr EC 50 (for crustacea) > 1 to ≤10 mg/l and/or
72 or 96 hr ErC 50 (for algae or other aquatic plants) > 1 to ≤10 mg/l
The following acute values were determined:
LC50(96h) = 2.55 mg/l (nominal) for Brachidanio rerio
EL50(48h) = 4.9 mg/l (WAF) for Daphnia magna
ErL50(72h) = 3.9 mg/l (WAF) for Pseudokirchneriella subcapitata
Therefore, the substance does not need to be classified for acute (short-term) aquatic hazard.
With this consistent short-term data, and the fact that no biodegradation observed, 0% (O2 consumption) in 28 days (OECD TG 301D), the substance must be classified as Aquat. Chron. Cat. 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.
