Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Aquatic short-term (acute) toxicity

48-h EC50 (Daphnia magna): > 100 mg/L (nominal)

72-h EC50 (growth rate; Raphidocelis subcapitata): > 3.02 mg/L (geometric mean measured)

Aquatic long-term (chronic) toxicity

EC10 (grwoth rate; Raphidocelis subcapitata): 2.45 mg/L (geometric mean measured)

Biodegradation in water: screening tests

The substance is readily biodegradable (according to OECD criteria).

Partition coefficient octanol/water

Using KOWWIN v1.68 the log Pow of the test item was calculated to be -5.05 at 25 °C.

Classification, Labelling, and Packaging Regulation (EC) No 1272/2008

The available experimental test data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. The test substance was found to be readily biodegradable by OECD criteria. The log Pow of the test item was calculated to be -5.05 at 25 °C. The most sensitive test for the aquatic compartment was the toxicity test to algae (Raphidocelis subcapitata). The 72-h ErC10 and the ErC50 (growth rate) of the test substance was determined to be 2.45 and > 3.02 mg/L (geometric mean measured), respectively. The 72-h NOEC-values for both inhibition of growth rate and yield after 72 hours were 1.90 mg/L (geometric mean measured). The 48-h EC50 for Daphnia magna was determined to be > 100 mg/L (nominal). Based on these results, the substance is neither classified for short term (acute) aquatic toxicity, nor for long term (chronic) aquatic toxicity according to Regulation (EC) No 1272/2008 (CLP) as amended for the tenth time in Commission Regulation (EU) 2017/776.
