Additional information
Conclusion on classification
Environmental fate and pathway
Readily biodegradable
85.2% within 28 d (OECD 301B); read across
Bioaccumulation
The potential for bioaccumulation is expected to be low.
Aquatic acute toxicity
Fish
LC50 (96 h) = 4.256 mg a.i./L (geom. mean measured, OECD 236, D. rerio)
Aquatic invertebrates
EC50 (48 h) = 2.9 mg/L (arith. mean meas., OECD 202, D. magna)
Algae
ErC50 (72 h) = 13.47 mg/L (nominal, OECD 201, P. subcapitata)
Aquatic chronic toxicity
Algae
ErC10 (72 h) = 4.448 mg/L (nominal, OECD 201, P. subcapitata)
CLP
Based on the available data listed above, the most sensitive acute effect concentration was obtained for aquatic invertebrates, with an EC50 (48 h) of 2.9 mg/L (arithm. mean meas.). Thus, the substance does not need to be classified for acute aquatic toxicity according to the consolidated version of Regulation (EC) No 1272/2008 (CLP) and following amendments (ATPs).
The ErC10 (72 h) = 4.448 mg/L (nominal) for algae is the only chronic aquatic effect concentration available. In addition, the substance is readily biodegradable and the potential for bioaccumulation is expected to be low. Thus, the substance does not need to be classified for chronic aquatic toxicity according to the Regulation (EC) No 1272/2008 (CLP) and following amendments (ATPs).
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).
