Description of key information

C.I. Direct Blue 264 is classified as non flammable.

Key value for chemical safety assessment

Flammability:
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.
