Conclusion on classification
The available experimental test data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008.
For the acute aquatic toxicity classification, the results of the ready biodegradation test and the results of short-term toxicity tests for the source substance Direct Red 83:1 are taken into account. In this casethe result of the short-term toxicity test to algae is considered to be the worst case witha 72 h-ErC50 of 2.81 mg/L (for the test substance with a purity of 69.96 %) and a 72 h-ErC50 of 1.97 mg/L (for the test substance with a purity of 100 %).In addition, the test substance is considered to be not readily biodegradable.
For the chronic aquatic toxicity classification, the results of the ready biodegradation test, the results of the short-term toxicity and the results of the long-term toxicity are taken into account for the source substance Direct Red 83:1. In this case there are adequate toxicity data for one trophic level (algae). The result of the short-term toxicity test to algae is considered to be the worst case with a 72 h-ErC50 of 2.81 mg/L (for the test substance with a purity of 69.96 %) and a 72 h-ErC50 of 1.97 mg/L (for the test substance with purity of 100 %) and a 72 h-ErC10 of 0.54 mg/L (for the test substance with a purity of 69.96 %) and a 72 h-ErC10 of 0.38 mg/L (for the test substance with a purity of 100 %).
Based on these results the substance the source substance Direct Red 83:1 is not classified as acute aquatic toxicity and based on these results the substance is classified as chronic aquatic toxicity Cat. 2; H411:Toxic to aquatic life with long lasting effects according to Regulation (EC) No 1272/2008 (CLP) as amended for the fourteenth time in Regulation (EU) 2020/217.Based on the read-across characteristics explained in the previous chapters, it is justified that the target substance Direct Red 243 acquires also this classification.
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).
