Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
The test substance, Centralit, was tested in acute immobilisation test on Daphnia magna.
The test was performed according to method C.2 – Daphnia sp. Acute Immobilisation Test, Council Regulation (EC) No. 440/2008, published in O.J.L 142, 2008.
Since the test substance is poorly soluble in dilution water at concentrations needed for the test, the saturated solutions of the test substance in dilution water were prepared.
The full test was performed in range of test substance nominal concentrations 10 - 49 mg.L-1. Samples for analytical determination were taken at the beginning and at the end of the test.
Key value for chemical safety assessment
Fresh water invertebrates
Fresh water invertebrates
- Effect concentration:
- 14.3 mg/L
Additional information
The analytical results showed that the test substance Centralit was stable in dilution water at conditions of the test, therefore the nominal concentrations were used for all evaluations and results.
The value EC50 (48h) for daphnia magna was used for C&L and for Chemical Safety Assessment.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
