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. 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. In addition, the substance is soluble in water at room temperature and forms a stable solution with water. No reactions with water or emission of flammable gases have ever been noted. Furthermore, for soluble dyes a reaction with water is not a desirable property from the use point of view. Therefore, the substance cannot be classified as a substance that in contact with water may react generating flammable gases.

Moreover, an existing study on a similar substance was considered as supporting information:

The substance was tested in a screening test according to Grewer. No spontaneous combustion was observed using this testing method. Glimmering from 220 °C.

Based on the available data, the structural similarity between the substances, Acid Green 073:1 can be considered as non autoflammable

The evaluation of the similarity between the Target Substance and the Similar Substance 02 is attached at section 13.
