Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Short-term toxicity to fish
The LC0 after 96 h was determined to be 100 mg/L. Therefore, the LC50 is determined to be higher than 100 mg/L.
Short-term toxicity to aquatic invertebrates
The EC50 of the test item on Daphnia magna was determined after 48 h exposure to be 19.7 mg/L. The NOEC was determined to be 3 mg/L.
Toxicity to aquatic algae
The 72-h EC10 and EC50 based on growth rate were determined to be 2.5 and 3.4 mg/L, respectively. The NOEC based on growth rate and yield was determined to be 1.4 mg/L.
Toxicity to microorganisms
Under the conditions of the performed test, a strong test item effect on the pH was established. Without pH adjustment the EC50 value of test item was determined as 618.8 mg/L (95% confidence limits: 514.6 – 757.8 mg/L), (1000 mg/L > EC50 > 100 mg/L) and the NOEC calculated as 100 mg/L. With an additional pH adjustment, neutralization step, the EC50 became higher than 1000 mg/L (EC50 > 1000 mg/L) and the NOEC was determined as 320 mg/L.
Additional information
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.
