Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 geometric mean of LC0 and LC100 was calculated to be 0.9 mg/L. The short-term toxicity to fish study was disregarded due to major methodical deficiencies (reference 6.1.1-1).
Short-term toxicity to aquatic invertebrates
The acute toxicity to the freshwater invertebrate Daphnia magna has been investigated according to OECD Guideline 202 in a semi-static test. Based on geometric mean measured concentrations of the test material, the 48 h-EC50 was determined to be 294 µg/L (95% confidence limits: 129 – 671 µg/L) (reference 6.1.3-1).
Toxicity to algae and cyanobacteria
The test item was tested to Pseudokirchneriella subcapitata in an open static test system according to OECD 201 (2011). Under the test conditions, the EC50-vaiues for inhibition of growth rate (ErC50) and yield (EyC50) after 72 hours were > 1.41 mg/L and 0.870 (0.764 - 0.999) mg/L, respectively. The EC10 value for growth rate was 0.785 mg/L (reference 6.1.5-1).
Toxicity to microorganisms
A test on respiration inhibition using activated sludge of a predominantly domestic sewage treatment plant was conducted in a method similar to OECD 209. After 30 min of exposure the EC50 was determined to be > 10000 mg/L (reference 6.1.7-1).
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.
