Description of key information
Two non-GLP screening test studies have been performed to assess the possible toxicity of the test
substance to fresh water crustaceans.
No analytical information is available to verify the concentration of the test substance in solution.
As the test substance is very poorly water soluble it is proposed to conduct a long term aquatic toxicity
test to fulfil this endpoint as indicated in the REACH guidance
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.
