Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Aquatic toxicity

To assess the short-term toxicity of the registered substance to aquatic organisms, QSAR predictions of reliability 1 (Klimisch rating), were performed for the three aquatic trophic levels (algae, aquatic invertebrate and fish), and a reliability-3 study on Zebra fish was performed.

Among all acute data available, the reliability-3 study gave the lowest fish 96h-LC50 (30.5 mg/L) but the procedural average recovery was 46.9%. Multipling this value by two gives a closer 96h-LC50 value (60.8 mg/L) to the valid QSAR value of 71 mg/L.

For the aquatic invertebrate Daphnia magna the predicted 48h-EC50 was 175 mg/L and for the algal growth inhibition test, the predicted 72h-ErC50 was 367 mg/L.

Environmental fate and pathways

According to the key ready biodegradability test, the registered substance is readily biodegradable (88% biodegradation after 28 days, satisfied the 10-day window validation criterion) and therefore is not persistent in the environment. In addition, the registered substance has a log Kow of 1.3, suggesting that it does not have an important affinity for lipids present in organisms, and has consequently a low potential of bioaccumulation. The registered substance is not considered to be bioaccumulative according to CLP and PBT criteria.

Conclusion on classification

QSAR predictions allowed to obtain short-term E(L)C50 values for the three trophic levels (fish, aquatic invertebrate and algae) of respectively 71 mg/L, 175 mg/L and 367 mg/L, so lowest E(L)C50 value between 10 and 100 mg/L.

The substance has a log Kow of 1,3 and is readily biodegradable.

Classification according to the Annex I of the Regulation (EC) No1272/2008 (CLP): The registered substance is not classified for the environment.
