Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Biodegradation

Biodegradation: Readily biodegradable: 98.2% within 28 d (OECD 301A)

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

Aquatic acute toxicity

Fish

LC50 (96 h) = 95.8 mg/L (nominal) for D. rerio (OECD 203)

Aquatic invertebrates

EC50 (48 h) = 38.4 mg/L (nominal) for Daphnia magna (OECD 202)

Algae

ErC50 (72 h) = 79.0 mg/L (geometric mean measured) for Desmodesmus subspicatus (OECD 201); read across

Aquatic chronic toxicity

Algae

NOErC (72 h) = 9.2 mg/L (geometric mean measured) for Desmodesmus subspicatus (OECD 201); 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) = 38.4 mg/L (nominal). Thus, the substance does not need to be classified for acute aquatic toxicity according to the Regulation (EC) No 1272/2008 (CLP) and following amendments (ATPs).

The NOErC (72 h) = 9.2 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. 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).
