Additional information

Two studies on the acute toxicity towards invertebrates (equivalent to OECD 202 and according to OECD 202, respectively; reliability category 1) for Pigment Yellow 12 and 13 are available. For both of these pigments consistently no toxicity to Daphnia magna could be found in the tests. Nominal concentrations far above the solubility limit of the pigments had been applied. Therefore, the Diarylide Yellow Pigments are to be regarded as acutely nontoxic to invertebrates.
