Key value for chemical safety assessment

Physical state at 20°C and 1013 hPa:

Additional information

Based on handling and visual observation (qualitative assessment) the substance to be registered can be described as an odourless light blue powder. Furthermore the outcomes deriving from the Differential scanning calorimetry (DSC) performed on the major of the two components of the substance, can confirm that the substance is solid at room temperature.

Direct Blue 080:1 is a multiconstituent substance composed by the acidic and the sodium salt forms of the same structure (58.44 % and 13.55 % of the substance respectively). Considering the great similarity of the molecules, the composition of the substance Direct Blue 080:1 the Read Across approach with Direct Blue 080 is considered acceptable.
