Key value for chemical safety assessment

non flammable

Additional information

Solid, burning rate

C.I. Direct Blue 264 did not burn down or burn up (UN N.1).

Contact with water

Data waiving: does not emit flammable gases in contact with water

C.I. Direct Blue 264 is not able to react with water, because the central copper-ion is already in its maximum oxidized stage.

Pyrophoric properties

Data waiving: no pyrophoric properties

Experience in production or handling; C.I. Direct Blue 264 is known to be stable at room temperature.

Justification for classification or non-classification

As C.I. Direct Blue 264 did not burn down or burn up and it does not have pyrophoric properties nor a reaction with water is expectable, it can be concluded that a classification as flammable is unjustified.
