Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Direct Blue 080:1 is an odourless and very soluble light powder. The substance is expected to decompose before melting and boiling, for this reason neither vapour pressure nor flash point are defined. Surface tension is not a desirable property of the substance.

Direct Blue 080:1 is expected to have a relative density of ca. 1.729 and a log Kow of ca.-4.03. The median mass diameter after 2 minutes of ultrasonic treatment is in the range of the inhalable fraction (10 – 100 µm).

The compound is presumably non flammable, non oxidising, non explosive and has no spontaneous ignition property.

 

The physical and chemical properties of the multicomponent Direct Blue 080:1 have been evaluated based on the tests conducted on one of the two components, the substance is composed by the sodium salt and the acidic form of the same substance.

The complete Justification for the Read Across approach is reported in each endpoint summary interested.
