Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

Conclusion on classification

Environmental fate and pathways

Readily biodegradable: 85.2% in 28 d (OECD 301 B); read-across

Bioaccumulation: The potential for bioaccumulation is expected to be low.

Aquatic acute toxicity

Fish

LC50 (96 h) = 14.4 mg/L (nominal, Danio rerio, OECD 203)

Aquatic invertebrates

EC50 (48 h) = 10.0 mg/L (nominal, Daphnia magna, OECD 202)

Algae

ErC50 (72 h) = 13.47 mg/L (nominal, OECD 201, P. subcapitata); read-across

Aquatic chronic toxicity

Algae

ErC10 (72 h) = 4.448 mg/L (nominal, OECD 201, P. subcapitata); read-across

CLP

Based on the available data listed above, the most sensitive acute effect concentration was obtained for Daphnia magna, with an EC50 (48 h) = 10.0 mg/L (nominal ). 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 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 needs not to be assessed based on acute toxicity data. Therefore, the substance does not need to be classified for chronic aquatic toxicity according to the consolidated version of Regulation (EC) No 1272/2008 (CLP) and following amendments (ATPs).
