Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

In the absence of aquatic chronic toxicity information, the classification was based on the lowest short-term aquatic toxicity value (the EC50 value of 320 mg/L from the 72-hour Selenastrum capricornutum aquatic alga assay and the EC50 value of 320 mg/L from the 48-hour Daphnia magna aquatic invertebrate assay) from the three trophic levels (fish, aquatic invertebrates and aquatic algae). The substance was shown to be readily biodegradable in the environment. The substance has an estimated octanol-water partition coefficient (log Kow) of 1.11, which is substantially below the criterion (log Kow≥ 4.0) above which a substance exhibits the potential for chronic toxicity. Therefore, the substance was not classified with respect to the aquatic environment.
