Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

One test is available on the similar substance 1.

The test substance was tested in acute immobilisation test on Daphnia magna, according to method C.2 – Daphnia sp. Acute Immobilisation Test, Council Regulation (EC) No. 440/2008.

The preliminary test was performed in a range of the test substance nominal concentrations 1 – 100 mg·L-1.Based on toxicity of the test substance found in the preliminary test, the definitive test was performed in appropriate concentration range. The definitive test was performed static, in a range of the test substance nominal concentrations 1 – 50 mg·L-1.

The study was performed without analytical determination of the test substance concentrations. Only the concentrations of Total organic carbon (TOC) in the lowest and in the highest tested concentration were analysed in the preliminary and definitive test.Samples for determination of the TOC concentrations were taken at the beginning and at the endof the test. The nominal concentrations were used for all evaluation and results.
