Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

A study was conducted in accordance with the OECD Guideline for Testing of Chemicals No.202 “Daphnia sp., Acute Immobilisation Test” (2004). A water-accommodated fraction (WAF, test conc. 100 mg/L) was used to expose the test species to the test substance because the substance was poorly water-soluble and difficult to be dissolved stably in the test solutions. The result given below was calculated from the time-weighted mean of measured concentrations. The median effect concentration (EC50) for immobilisation is mentioned as [>test concentration] because this test was a limit test and the immobility was 0% in Conc. 1. The 48-hour median effect concentration (EC50) found was >0.0265 mg/L (Conc. determined by HPLC).
