Description of key information
The toxicity of the test item was investigated in a study conducted according to OECD Guideline 201 (Alga, Growth Inhibition Test) and EU Method C.3 (Algal Inhibition test). Due to the low water solubility a supersaturated dispersion with a loading rate of 100 mg/L nominal was prepared by sonication, stirring, and filtration. The measured test item concentration in the undiluted filtrate was 0.0024 mg/L at test start and 0.0021 mg/L after 72 h. In the control and at any concentration tested no effects on growth rate, biomass or other signs of intoxication were determined during the test period of 72 hours (72 h NOEC >=100 mg/L nominal; 72 h EC50 > 100 mg/L nominal based on the loading rate).
Key value for chemical safety assessment
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.
