Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Valid acute toxicity tests with the test substance are available for three freshwater species from three trophic levels. In all tests the EC/LC50 was higher than the water solubility of the substance (< 0.5 mg/L).

In the algae study no effects were observed in the tested undiluted filtrate with a loading rate of 100 mg/L (NOEC >= 0.011 mg/L). In the Daphnia study 5% immobilization was observed within the limits of water solubility (EC50 > water solubility). In all three fish tests no mortality was observed within water solubility. The key study (Scheerbaum, 1996) showed that even in an emulsion with 100 mg/L nominal, no effects were observed (LC50 > 82 mg/L measured conc.). A study using an emulsifier (Caspers, 1996) showed as well no mortality up to the water solubility limit (LC0 >= 0.22 mg/L; loading rate 2.5 mg/L). In a third study (Caspers, 1992) the toxicity was tested far above the water solubility of the substance (62 to 1000 mg/L). Up to 250 mg/L (nominal) no mortality was observed. The LC50 was determined to be 613 mg/L (nominal), where the mortality can be attributed to physical effects instead of systemic effects.


Additionally to the algae test, one further long-term tests with aquatic invertebrates is available. In the flow-through test the EC10 (reproduction) was determined to be 0.0084 mg/L based on mean measured test item concentrations. 

The evaluation of the long-term toxicity on fish is still ongoing (see BoA case number A-010-2018 with a deadline of  25 February 2024).


Furthermore a valid respiratory inhibition study with activated sludge is available: The substance did not inhibit the microbial activity in activated sludge up to a nominal concentration of 1000 mg/L. At 10000 mg/L 14.3% inhibition were observed. The EC50 is > 10000 mg/L and the substance is not considered to be toxic to sewage sludge bacteria.
