Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In a 96-hour acute toxicity test on Zebrafish (Danio rerio) the source test item had no toxic effect on fish up to the limit concentration of 100 mg/L. Accordingly, the 96-h LC50 value was determined to be > 100 mg/L. The 96-h NOEC was determined to be 100 mg/L. Based on the structural similarities between the source and the target substance, the target substance is also considered to show no toxicity to fish up to the limit concentration.
Short-term toxicity to aquatic invertebrates
In a 48-hour acute toxicity test on Daphnia magna, the obtained results showed that the source test item had no toxic effects on the mobility of Daphnia up to the concentration of 100 mg/L. The 48-h EC50 was determined to be higher than 100 mg/L and the 48-h NOEC was determined to be 100 mg/L. A 24-h immobilisation study with Daphnia magna supports the obtained results in the 48-h test. The 24-h EC50 was determined to be >100 mg/L. Based on the structural similarities between the source and the target substance, the target substance is also considered to not be toxic to aquatic invertebrates up to the limit concentration.
Toxicity to aquatic algae and cyanobacteria
The 72-h NOEC based on growth rate and yield of the source test item was determined to be 100 mg/L, while the 72-h LOEC based on growth rate and yield was determined to be > 100 mg/L. The 72-h EC10, EC20 and EC50 values were determined to be > 100 mg/L. Based on the structural similarities between the source and the target substance, the target substance is also considered to not be toxic to aquatic algae up to the limit concentration.
Toxicity to microorganisms
Under the conditions of the performed Activated Sludge Respiration Inhibition Test, the EC10 and EC50 values of the source test item were determined as greater than 1000 mg/L. Based on the statistical evaluation in this test the NOEC was 1000 mg/L. Based on the structural similarities between the source and the target substance, the target substance is also considered to not be toxic to microorganosms up to 1000 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.
