Description of key information

Additional information

Acid Blue 158:1 is an odourless and soluble blue 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.

Acid Blue 158:1 is expected to have a relative density of ca. 1.732 and a log Kow of ca. -2.4509. 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 Acid Blue 158:1 have been evaluated based on the tests conducted on similar substance 1, that differs only in the salification but has the same structure of the substance.

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