Key value for chemical safety assessment
Additional information
For the assessment of toxicity of the Diarylide Yellow Pigments towards aquatic plants two reliable studies on Pigment Yellow 12 (reliability category 1 and 2) and one reliable study (reliability category 1) on Pigment Yellow 83 had been performed with the green algae Desmodesmus subspicatus (Pigment Yellow 12) and Selenastrum capricornutum (Pigment Yellow 83). For all three studies with nominal pigment concentrations far above the solubility limit no toxicity towards algae could be observed. Judging from these experimental results the Diarylide Yellow Pigments are to be regarded as nontoxic to aquatic plants / algae.
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).
