Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 toxicity studies evaluating the toxicity of the substance to aquatic organisms are available for three different trophic levels. All studies were performed according to international guidelines and GLP. Freshwater algae (Pseudokirchneriella subcapitata) turned out to be the most sensitive species with an ErC50 (72 h) of 1.6 mg/L/ErC10 (72 h) of 0.86 mg/L followed by aquatic invertebrates (Daphnia magna; EC50 (48 h): 20 mg/L) and freshwater fish (Danio rerio; LC50 (96 h) > 6.2 mg/L). The toxicity to the microbial community was investigated using the toxicity control from a standard biodegradation study. A degradation of 63% after 14 d did not indicate any toxic effects of the test item to the inoculum at a concentration of 1.5 mg/L. Thus, a NOEC (14 d) of ≥ 1.5 mg/L was derived for the activated sludge microorganisms.
