Additional information

The substance is produced and regularly used for many years in Europe, transported in various conditions and in various amounts. Evidence connected to the long experience in handling, use and transport of the substance confirms the non- self-ignition properties. Thus, the substance is expected to be an air-stable compound at room temperature over a prolonged period of time (days), without noticeable or undesirable reactions. Many dyes were tested and does not show low auto-ignition temperature. The substance does not melt up to 450 °C and is not flammable. In conclusion, a potential for spontaneous ignition is not expected: the substance can be considered as a no-pyrophoric and no-self-heating solid because it is not liable to self-heat by reaction with air and without energy supply.

Self-ignition potential of a structural analogue of Direct Green 026, i.e. Reactive Red 195, is under assessment. The study is currently in progress and will be used to support the expert judgement.
