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 bioaccumulation prediction by means of the BCFBAF program (v3.01) results in an aquatic BCF of 3.162 L/kg wet weight. Thus, it is concluded that Basic Blue 41 methyl sulfate has no considerable bioaccumulation potential in aquatic species.

In addition, based on physicochemical properties and data from human toxicity tests, there appears to be a good oral bioavailability but limited dermal or inhalation uptake of Basic Blue 41. Also, there is wide tissue distribution of Basic Blue 41 after oral exposure, but bioaccumulation is unlikely. (For details please refer to the endpoint summary for toxicokinetics, metabolism and distribution.)
