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.
