Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Based on the integrated testing strategy [ECHA R.7c, 2008] a stepwise approach to hazard identification on terrestrial organisms is required. Tests of toxicity on earthworm were considered as first step, due to the fact that earthworms are exposed via multiple uptake routes (soil pore water, ingestion of soil material, soil air, secondary poisoning). For the described pigment an acute toxicity test on earthworms (Eisenia fetida) was performed. In this test no acute effects on earthworms occurred after 14 days exposure to 1000 mg/kg soil dw. This confirms the results from the aquatic tests where no hazard was identified. It can be expected that the pigment is essentially not bioavailable, due to the large molecular size together with the negligible low solubility. Therefore it can be assumed with sufficient confidence, that further tests on terrestrial organisms would not provide any additional information for improving the risk assessment. Hence tests on plants and terrestrial microorganisms are not required.
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.
