Description of key information

Additional information
The toxicity of the test substance to Desmodesmus subspicatus was investigated in a GLP guideline study according to OECD 201. The EC50 (72h, growth rate) was determined to exceed the highest tested concentration of 120 mg/L, based on the analytically verified nominal concentration (BASF SE 60E0535/11X283, 2012). Therefore, the test substance is considered to be "with high probability not harmful to aquatic algae".
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.
