Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Due to the poor water solubility, yet rapid hydrolysis of the test item, test solutions for aquatic toxicity testing had to be prepared following a special protocol. For all reported key studies the test item was mixed with dilution water at a relatively high nominal loading rate of 10 g/L, followed by vigorous stirring at 37 ± 2 °C for 7 days. This was done to maximise concentrations of the test material, hence generating a solution of several, largely non-identifiable, breakdown products. The determination of the effect concentrations was based on the geometric mean of total dissolved test material, calculated from the measured concentrations of the identifiable breakdown product at the beginning and at the end of the test, or test solution renewal, respectively.
The LC50 (96 h) on the fish Danio rerio was determined to be 7.3 mg/L in a study according to OECD guideline 203.
The EC50 (48 h) on Daphnia magna was determined to be 32 mg/L in a study according to OECD guideline 202.
The ErC50 (72 h) for algae (Desmodesmus subspicatus) was determined to be 41 mg/L in a study according to OECD guideline 201.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
