Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Physicochemical processes like phototransformation and hydrolysis are not relevant for the black pigment due to the lack of fluorophoric groups and non-measurable water solubility (at all pH-values). Lead is present as lanarkite predominately. Formation of different Pb-hydroxides may occur, but the chemical assessment cannot make any differentiation among the different Pb-species (pooling of different speciation forms). In addition, magnetite (Fe3O4) is virtually insoluble in the environment at the prevailing pH-domain.
Consequently, (abiotic) degradation is an irrelevant process for the black pigment.
Additional 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.
