Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Hydrolysis: hydrolytically stable at pH 5, 7 and 9 (OECD 111)

Simulation tests: not rapidly biodegradable

 

Bioaccumulation

Log Kow: -1.36 at 23 °C (OECD 107, shake-flask method)

 

Aquatic acute toxicity (freshwater)

For fish: 96 h, LC50 (Oncorhynchus mykiss, OECD 203): > 100 mg test item/L (nominal)

For aquatic invertebrates: 48 h, EC50 (Daphnia magna, OECD 202): > 100 mg test item/L (nominal)

For algae: 72 h, ErC50 (Pseudokirchneriella subcapitata, OECD 201): 29.8 mg a.i./L (mean measured)

For aquatic plants: 7 d, EC50 (Lemna gibba, EPA OPPS 850.4400): 0.110 mg a.i./L (mean measured)

 

Aquatic acute toxicity (marine water)

For fish: 96 h, LC50 (Cyprinodon variegatus, OECD 203): > 100 mg a.i./L (nominal)

For aquatic invertebrates: 48 h, EC50 (Americamysis bahia, EPA OPP 72-3): 1.1 mg a.i./L (nominal)

For algae/aquatic plant: 72 h, ErC50 (Skeletonema costatum, OECD 201): 15.7 mg a.i./L (mean measured)

 

Aquatic chronic toxicity (freshwater)

For fish: 21 d, NOEC (Pimephales promelas, OECD 210): 0.58 mg a.i./L (measured)

For aquatic invertebrates: 21 d, NOEC (Daphnia magna, OECD 211): 12.8 mg a.i./L (measured)

For algae: 72 h, NOErC (Pseudokirchneriella subcapitata, OECD 201): 6.4 mg a.i./L (mean measured)

For aquatic plants: 7 d, NOEC (Lemna gibba, OPPTS 850.4400): 0.00957 mg a.i./L (mean measured)

Aquatic chronic toxicity (marine water)

For fish: no data available

For aquatic invertebrates: no data available

For algae/aquatic plant: 72 h, NOErC (Skeletonema costatum, OECD 201): 6.4 mg a.i./L (mean measured)

 

Based on the data above the substance is not rapidly degradable. Aquatic plants turned out to be the most sensitive species (EC50 (7 d) 0.110 mg a.i./L; NOEC (7 d) 0.00957 mg a.i./L). This study investigates both, the acute and chronic effects. Thus, the test item has to be classified as Acute Cat. 1 (H400) and Chronic Cat. 1 (H410) according to Regulation (EC) No. 1272/2008 (CLP) and following amendments (ATPs). In conclusion the substance is labelled as Chronic Cat. 1 (H410).

M-factor for acute aquatic toxicity: 1

M-factor for chronic aquatic toxicity: 10
