Description of key information
Red disazo condensation pigments are with high probability acutely not harmful to fish.
No toxic effects occur at the range of the substances solubility.
EC50 (96h) > 1 mg/L (nominal) for Brachydanio rerio (OECD 203)
Key value for chemical safety assessment
Additional information
The acute aquatic toxicity on fish was investigated in GLP guideline studies according to OECD 203 for two ‘red disazo condensation pigments’(CAS 68516-75-6 and CAS 71566-54-6) [DR.U.NOACK-LABORATORIEN, 2012; lnstitute of lndustrial Organic Chemistry, Branch Pszczyna, 2012]. Both studies used the zebrafish Danio rerio as test species. Based on the low water solubility of the test item, saturated stock solutions were prepared and the tests were conducted as limit tests with nominal concentrations of 1 mg/L (CAS 68516-75-6) and 100 mg/L (CAS 71566-54-6), respectively. After 96 hours of exposure no toxic effects on fish within the range of solubility were observed.
