Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusion on classification

Classification related key information:

 

Biodegradation in water: Not readily biodegradable (11.3 % after 28d)

Bioaccumulation: Log Kow = 2.73

 

Aquatic acute toxicity:

- to Fish: LC50 (96 h) = 9.7 mg/L (meas. TWA) for Oncorhynchus mykiss (OECD 203)

- to aquatic invertebrates: EC50 (48 h) = 3.403 mg/L (measured) for Daphnia magna (OECD 202)

- to algae: ECr50 (72 h) = 5.59 mg/L (meas. TWA) for Raphidocelis subcapitata (OECD 201)

 

Aquatic chronic toxicity:

- to Fish: NOEC (35 d) ≥0.11 mg/L (meas. TWA) for Danio rerio (OECD 210)

- to aquatic invertebrates NOEC (21d) = 0.45 mg/L (meas. TWA) for Daphnia magna (OECD 211)

- to Algae: NOEC (72h) = 1.61 mg/L (meas. TWA) for Raphidocelis subcapitata (OECD 201)

 

CLP:

According to the data listed above the test substance is not rapidly biodegradable (11.3 % after 28 d) and has a low potential to bioaccumulate (log Kow < 3). The most sensitive acute effect was obtained for Daphnia magna with an EC50 (48 h) of 3.403 mg/L. The most sensitive chronic effect was the reported NOEC (21d) of 0.45 mg/L in a chronic toxicity study with Daphnia magna. Based on the available data the substance needs to be classified and labelled as Aquatic Chronic 2.
