Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
The pigment has to be classified as chronically harmful to aquatic organisms based on its Ni solubility.
Key value for chemical safety assessment
Additional information
With a high probability P.I Pigment Green 50 itself is not chronically harmful to aquatic organisms.
However, 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
4 µg Ni/L and < 1 µg Ni/L at pH 5.5 and pH 8.5 for the 28 day test, respectively and for a loading rate of 1 mg/L. Thus, the dissolved Ni concentration exceeds the chronic ERV at acidic conditions, whereas at alkaline conditions the dissolved Ni were well below the ERV.
Thus, the Pigment 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 attachment under endpoint summary "Ecotoxicological information".
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
