Additional information
Conclusion on classification
Adequate chronic toxicity data are not available for Direct Black 168NaLi. The substance is not readily biodegradable, the log Kow is -2.28 and the water solubility is 67.28 mg/L (very soluble).
The available data on aquatic toxicity of the substance, are short-term toxicity data gathered by read-across from a structural analogue EC50(fish)=117.7 mg/L, EC50(daphnia)=64.9 mg/L and LC50(algae)=17.4 mg/L.
Based on the fact that no L(E)C50 was recorded to be <= 1 mg/L, the criteria for classification for short-term aquatic hazard (category 1) according to CLP Regulation 1272/2008 are not met.
Based on the results of short-term toxicity for fish, daphnia and algae (effects recorded in the range of 10 - 100 mg/L), together with a
log Kow value of -2.28, according to CLP Regulation 1272/2008 Criteria of table 4.1.0.b) iii), the substance is classified for long-term aquatic hazard, Category 3 (H412).
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).
