Description of key information
With high probability acutely not harmful to aquatic algae. No toxic effects occur at the range of the substances solubility.
Key value for chemical safety assessment
Additional information
Since no data of acute toxicity on aquatic algae for the described pigment are available, read-across to similar pigments (EC 600-735-2 and CAS 30125-47-4) is used to cover this endpoint. The toxicity on aquatic algae was investigated in two GLP guideline studies according to OECD 201 [BASF SE 2014; Department of Product Safety BASF SE 2012]. The studies were conducted with the green algae Pseudokirchneriella subcapitata, respectively, Desmodesmus subspicatus as test species. Based on the low water solubility of both test items saturated solution were prepared. For CAS 30125-47-4 a limit test was conducted using a loading rate of 100 mg/L. For EC 600-735-2 a full concentration range was tested preparing separate saturated solutions according to OECD Guidance Document 23. After 72 hours of exposure no toxic effects on algae up to the highest test concentration were observed in both studies.
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.
