Short-term toxicity to aquatic invertebrates
Administrative data

Description of key information
The test substance is acutely very toxic to aquatic invertebrates.
Key value for chemical safety assessment
Additional information
Only one reliable study on short-term toxicity to aquatic invertebrates is available. In the key study (Institute of Industrial organic Chemistry Branch Pszczyna, 2012), young Daphnia magna (< 24 h old) were exposed to the test item for 48 hours in accordance with OECD guideline 202 (2004). Nominal concentrations of 0.25, 0.5, 1.0, 2.0 and 4.0 mg/L were used. The chemical analysis confirmed the stability and correct concentration of the test substance (95.25 – 102.00 % of nominal after 0 h and 92.25 –100.00% of nominal after 48h).The 48 hour EC50 was determined to be 0.88 mg/L. Therefore, the test substance is acutely very toxic to aquatic invertebrates.
A second unreliable study is available. However, due to the high amount of emulsifier, a slight precipitation at concentrations >10 mg/l at 24 h exposure and the short duration of 24 h , the test was disregarded.
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.
