Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key information for classification

Degradation

Biodegradation: not readily biodegradable (1% degradation after 28 d (O2 consumption, OECD 301F)

Simulation tests: not rapidly biodegradable

 

Bioaccumulation

BCF (fish, Lepomis macrochirus): < 2 (OECD 305, lipid normalized steady state as well as growth and lipid corrected kinetic BCF)

 

Aquatic acute toxicity

For fish: 96 h, LC50 (Oncorhynchus mykiss, OECD 203): > 10 mg a.i./L (nominal)

For aquatic invertebrates: 48 h, EC50 (Daphnia magna, OECD 202): 0.1733 mg a.i./L (nominal)

For algae/aquatic plant: 72 h, ErC50 (Navicula pelliculosa, OECD 201): > 3.19 mg a.i./L (measured)

 

Aquatic chronic toxicity

For fish: 33 d, NOEC (Pimephales promelas, OECD 210): 2.5 mg a.i./L (nominal)

For aquatic invertebrates: 28 d, EC10 (Chironomus riparius, OECD 219): 0.00071 mg a.i./L

For algae/aquatic plant: 72 h, NOErC (Navicula pelliculosa, OECD 201): 0.285 mg a.i./L (measured)

 

Based on the data above, the acute aquatic toxicity EC50 (48 h) for Daphnia magna is < 1 mg/L. Thus, the substance needs to be classified as environmental hazard Acute Cat. 1 (H400) according to the consolidated version of Regulation (EC) No 1272/2008 (CLP) including all further amendments (ATPs).

M-factor for acute aquatic toxicity: 1

 

The test item is considered to be not rapidly degradable. Valid chronic toxicity data are available for fish, invertebrates and algae – the lowest EC10 (28 d) is 0.00071 mg/L for Chironomus riparius. Thus, the substance needs to be classified and labelled as long-term aquatic hazard Chronic Cat. 1 (H410) according to the consolidated version of Regulation (EC) No 1272/2008 (CLP) including all further amendments (ATPs).

M-factor for chronic aquatic toxicity: 100
