Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 two trophic levels (fish and algae). The acute effect values for fish (Oryzias latipes) and algae (Raphidocelis subcapitata) are 0.97 mg/L and 4.54 mg/L, respectively. Since the lowest acute toxicity value is < 1 mg/L, the substance needs to be classified as Aquatic Acute Category 1 (H400) with M-factor 1 according to EU CLP (EC no. 1272/2008 and its amendments: Table 4.1.0; a).

 

Chronic toxicity data are available for three trophic levels (fish, invertebrate and algae). The long-term toxicity value for fish, invertebrate and algae were 0.074, 0.678 and 2.45 mg/L, respectively. The substance is not readily biodegradable and its lowest chronic toxicity value was > 0.01 but ≤ 0.1 mg/L. Based on this information, the substance needs to be classified as Chronic Cat. 1 (H410) with M-factor 1 according to EU CLP (EC 1272/2008 and its amendments: Table 4.1.0, (b) i).
