Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Low bioaccumulation potential expected.
Key value for chemical safety assessment
- Bioaccumulation potential:
- low bioaccumulation potential
Additional information
The assessment of toxicokinetic behaviour of Direct Blue 273 has been based on available information on Similar Substance 01, i.e. an isomer of Direct Blue 273 differing only for the position of a sulfonate group.
The information on the Similar Substance 01 derived from migrated NONS file, as per Article 25(3) request; permission to refer was granted by ECHA.
Details on the read across approach are included into the document attached in section 13.
Similar Substance 01 showed a low bioaccumulation potential on the basis of the toxicological studies conducted on the substance.
Due to the great similarity between Direct Blue 273 and the Similar Substance 01, Direct Blue 273 is expected to have a low bioaccumulation potential.
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.
