EC number: 269-047-4 | CAS number: 68186-85-6 This substance is identified in the Colour Index by Colour Index Constitution Number, C.I. 77377.
The pigment has to be classified as chronically harmful to aquatic organisms based on its Ni solubility.
One long term study on Daphnia magna is available. In the study conducted according to OECD 211 a NOEC (21 d) >1 mg/l was determined (MOE (2001). Thus, with a high probability P.I Pigment Green 50 itself (i.e. without the impurity Ni) is not chronically harmful to aquatic organisms.
The chronic ERV for Ni was estimated to be 2.4 µg/L according to OECD 29. The dissolved Ni concentrations of
P.I Pigment Green 50 (including the impurity Ni titanate) were
Thus, the impurity Ni titanate has to be classified as chronically harmful to aquatic organisms.
For details regarding the concentrations of Ni after different P. I Pigment Green 50 loading rates according to the
T/D Protocol (OECD 29) please see document attached in chapter 1.4. The Ecotoxicity Reference Values (ERVs) were taken from a document of the Nickel Consortia, 2010: Environmental Read-across approach. Please see attachmend under endpint summary "Ecotoxicological information".
