Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Short-term aquatic toxicity data are available for three trophic levels (fish, invertebrates and algae) for fresh- and saltwater species. The lowest acute effect values for fish (Cyprinodon variegatus), aquatic invertebrates (Crassostrea virginica) and algae (Navicula pelliculosa) are 0.028 mg/L, 0.0075 mg/L and 0.013 mg/L, respectively. As the lowest value is below 0.01 mg/L, the substance needs to be classified as Aquatic Acute 1 (H400), with an M-factor of 100, in accordance with EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation No. 1272/2008.

Long-term aquatic toxicity data are available for three trophic levels (fish, invertebrates and algae) for fresh- and saltwater species. The lowest chronic effect values for fish (Pimephales promelas), invertebrates (Americamysis bahia) and algae (Navicula pelliculosa) are 0.0014 mg/L, 0.0004 mg/L and 0.0035 mg/L, respectively. Regarding the adequate chronic aquatic toxicity data (lowest value ≤ 0.001 mg/L) and the substance being not readily biodegradable, the substance needs to be classified as Aquatic Chronic 1 (H410) with an M-factor of 100, 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) and Aquatic Chronic 1 (H410), with an M-factor of 100 for both acute and chronic hazard, in accordance with EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation No. 1272/2008.
