Justification for classification or non-classification

According to the CLP Regulation (EC 1272/2008), 2.7 section, flammable solids, powdered, granular or pasty substances or mixtures shall be classified as readily combustible solids when the time of burning of one or more of the test runs, performed in accordance with the test method described in Part III, sub-section 33.2.1, of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, is less than 45 seconds or the rate of burning is more than 2.2 mm/s.

Direct Blue 080:1is 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).

The flammability assessment was based on the Read Across approach: the test has been conducted on the sodium salt form. The difference between the two components (one is the sodium salt form and the other the acidic form of the same substance) has no influences on the flammability therefore the Read Across approach is considered acceptable. The sodium salt did not propagate burning of a 200 mm length of the strip in less than four minutes, therefore even the multiconstituent substance Direct Blue 080:1 is expected to be non flammable as the sodium salt form.

In conclusion, according to the CLP Regulation (EC 1272/2008) Direct Blue 080:1 is classified as NON flammable.
