Additional information
Conclusion on classification
Acute aquatic toxicity data are available for three trophic levels (fish, aquatic invertebrates and algae). The lowest acute toxicity value is a 96 -h LC50 of 38 mg/L in fish (O. mykiss). Since the lowest acute toxicity value is > 1 mg/L, the substance does not need to be classified as acute aquatic toxic according to EU CLP (EC no. 1272/2008 and its amendments: Table 4.1.0; a). A chronic aquatic endpoint is available only for freshwater algae (P. subcapitata) in which a 72 -h NOErC of 115 mg/L was determined. The lowest acute toxicity value falls > 10 to ≤ 100 mg/L. Additionally, the substance is not readily biodegradable. Based on all these data, the substance needs to be classified as Chronic Toxicity Category 3, H412 (harmful to aquatic life with long lasting effects) according to the CLP Regulations (EC) No 1272/2008.
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.
