Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Acute data is available for three trophic levels. The acute values were determined to be 344, 64 and >171 µg/L for fish (Oncorhynchus mykiss), daphnids (Daphnia magna) and algae (Raphidocelis subcapitata), respectively. As the lowest acute value is in the range of 0.01 - 0.1 mg/L, the substance needs to be classified as Aquatic Acute 1 (H400), with an M-factor of 10 in accordance with EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation No. 1272/2008.

 

Long-term aquatic toxicity data are available only for aquatic algae (Raphidocelis subcapitata) for which an ErC10 of 34 µg/L was determined. Based on the chronic data and the substance’s non-readily biodegradability, the substance needs to be classified as as Aquatic Chronic 1 (H410), with an M-factor of 1. Therefore, based on long-term toxicity data, the substance is classified as Aquatic Chronic 1 (H410) in accordance with EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation No. 1272/2008.

As only one reliable long-term toxicity endpoint is available, chronic classification needs to be based on both chronic and acute data of which the most stringent outcome is used for the final classification. Regarding acute data (lowest acute value in the range of 0.01 - 0.1 mg/L), the substance being not readily biodegradable and a log Kow of 4.38 (no experimental BCF available) the substance needs to be classified as Aquatic Chronic 1, with an M-factor of 1. Therefore, based on short-term toxicity data, the substance is classified as Aquatic Chronic 1 (H410) in accordance with EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation No. 1272/2008.

 

In conclusion, the substance is classified as Aquatic Acute 1 (H400), with an M-factor of 10 and Aquatic Chronic 1 (H410), with an M-factor of 1, as in accordance with EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation No. 1272/2008.
