Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Biodegradation

Readily biodegradable: 85.2% within 28 d (OECD 301B)

Bioaccumulation

The potential for bioaccumulation is expected to be low.

Aquatic acute toxicity

Fish

LC50 (96h) > 0.43 mg/L for D. rerio (OECD 203)

Aquatic invertebrates

EC50 (48h) = 0.43 mg/L for Daphnia magna (OECD 202)

Algae

ErC50 (72h) > 4.4 mg/L for Desmodesmus subspicatus (OECD 201)

Aquatic chronic toxicity

Algae

NOErC = 0.91 mg/L for Desmodesmus subspicatus (OECD 201)

Aquatic invertebrates

NOEC (21d) ≥ 0.183 mg/L for Daphnia magna (OECD 211)

CLP

Based on the available data listed above, the most sensitive acute effect concentration was obtained for Daphnia magna, with an EC50 (48 h) of 0.43 mg/L (measured). Thus, the substance needs to be classified as environmental hazard Category Acute 1, according to the Regulation (EC) No 1272/2008 (CLP) and following amendments (ATPs).

M-factor for acute aquatic toxicity: 1

The long-term results (NOEC) for aquatic invertebrates and algae are between 0.1 mg/L and 1 mg/L. In addition, the substance is readily biodegradable and has a low potential for bioaccumulation. Thus, the substance is classified and labelled as long-term aquatic hazard Category Chronic 3, according to Regulation (EC) No. 1272/2008 (CLP) and following amendments (ATPs).

M-factor for chronic aquatic toxicity: not applicable.
