Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Acute effect levels for the freshwater species tested are >100 mg/L (LC50 fish), 88 mg/L (48h-EC50 invertebrates) and >100 mg/L (algae; 72h-EC50 growth rate).

Long-term effect levels for the freshwater species tested are >110 mg/L (28d-NOEC fish), 7.95 mg/L (21d-NOEC invertebrates) and 4.6 mg/L (72h-NOErC algae).

Conclusion on classification

DSD: following the lowest acute effect level being in the range of 10 - 100 mg/L (88 mg/L, EC50 for daphnia), and the substance being not readily biodegradable, the substancewould be considered to be harmful to aquatic organisms and may cause long-term adverse effects in the aquatic compartment (R52/53). However, additional scientific evidence is available on the lack of long-term toxicity in the three trophic levels (fish, daphnids, algae) at a concentration of 1 mg/L. Therefore classification with R52/53 is not warranted. The substance is thus not classified for the environment according to the classification rules in DSD.

CLP: although the lowest acute effect level is in the range of 10 - 100 mg/L (88 mg/L, EC50 for invertebrates) and the substance is not readily biodegradable, no long term adverse effects are anticipated as the chronic toxicity NOEC's for fish, invertebrates and algae are > 1 mg/L; therefore, no classification for the environment is assigned according to the classification rules in CLP (taking into account the 2nd ATP).
