Key value for chemical safety assessment

Additional information

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).

Water solubility was determined by means of the OECD Guideline 105 (Water solubility), adopted 27.05.95 on the major component of the multiconstituent substance (Sodium salt form) and the tested substance results to have a water solubility of 26.12 g/l, therefore is considered as Very soluble.

Considering the high similarity between the structures and the composition of the substance, Direct Blue 080:1 is expected to be very soluble as described by the experimental data on the sodium salt.
