Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 0.23 mg/L, 0.24 mg/L and 0.0475 mg/L, respectively. The substance needs to be classified as Aquatic Acute 1 (H400), with an M-factor of 10.

Long-term aquatic toxicity data are available for aquatic invertebrates and algae. The chronic NOEC value for daphnids was determined to be 3.2 µg/L and the chronic ErC10 value for algae was determined to be 47.4 µg/L. The substance is not readily biodegradable. Based on this data, the substance needs to be classified as Aquatic Chronic 1 (H410) with an M-factor of 10.

 

As only two 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 <1 mg/L) and the substance being not readily biodegradable, the substance needs to be classified as Aquatic Chronic 1 with an M-factor of 10 (the resulting M-factor derived for acute aquatic hazard classification is also applied to the long-term aquatic hazard classification as Table 4.1.0 (a)(b, point iii) is used here for defining long-term aquatic hazard (Guidance on the Application of the CLP Criteria, v5.0, July 2017)).

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