Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Short-term aquatic toxicity data are available for three trophic levels (fish, invertebrates and algae). The acute effect values for fish (Danio rerio), invertebrates (Daphnia magna) and algae (Raphidocelis subcapitata) are 8.8 mg/L, 6.5 mg/L and 5.6 mg/L, respectively. Since the lowest acute toxicity value is > 1 mg/L, the substance does not need to be classified for aquatic acute hazard according to EU CLP (EC no. 1272/2008 and its amendments: Table 4.1.0; a).

Chronic toxicity data are available for algae. The algae 72-h ErC10 value is 3.5 mg/L. According to CLP Figure 4.1.1, the chronic classification has to be determined based on the chronic values for algae according to Table 4.1.0 (b) i, as well as the acute value for fish and invertebrates according to Table 4.1.0 (b) iii, and the most stringent outcome should be leading:

- The substance is not readily biodegradable and the lowest chronic toxicity value (algae) is > 1 mg/L. Based on this information, the substance does not need to be classified for aquatic chronic hazard according to Table 4.1.0, (b) i.

- The substance is not readily biodegradable, and acute toxicity values (aquatic fish and invertebrates) of > 1 but < 10 mg/L. Based on this information, the substance needs to be classified as Chronic Cat. 2 according to Table 4.1.0, (b) iii.

Overall, it can be concluded that the substance does not need to be classified for aquatic acute hazard, but it needs to be classified as Aquatic Chronic Cat. 2 (H411) according to EU CLP (EC 1272/2008 and its amendments).
