Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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). The acute effect values for fish (Oncorhynchus mykiss), daphnids (Daphnia magna) and algae (Pseudokirchneriella subcapitata) are > 0.7 mg/L, 0.87 mg/L and > 1.2 mg/L, respectively. The substance needs to be classified as Category Acute 1 (CLP table 4.1.0. (a)). Long-term aquatic toxicity data are available for algae and Daphnia for which a NOErC of 1.2 mg/L is found and 0.3 mg/l is derived on which bases it would receive Chronic 2 because the material is not readily degradable.

However, because only two reliable long-term toxicity endpoints are available, chronic classification needs to be based on both acute and chronic data and the worst case classification is to be applied. The substance is not readily biodegradable (has a BCF of <132 L/kg ww) and L(E)C50 values for the other tropic levels (algae and fish) are higher than WS based on which it will be not classified for chronic aquatic toxicity (Table 4.1.0 b, iii). Therefore, the substance needs to be classified as Category Acute 1 (H400) and Category Chronic 2 (H411), according to EU CLP (EC1272/2008 and its updates.
