Additional information

Handling experience with the substance to be registered indicates stable behaviour when in contact with air at room temperature over a prolonged period of time (days), without noticeable or undesirable reactions.

Thus it can be concluded thata potential for spontaneous ignition is not expected:

- The substancecan be considered as a non-pyrophoric solid because it does not react with air in small amounts in a more or less instantaneous manner;

-It can be considered as a non-self-heating solid because it does not react with air in large amounts and after an extended period of time;

The substanceis produced and used regularly since many years in Europe according to the above qualifications, transported by ship from outside Europe under various conditions and in various amounts. Evidence connected to the long experience in handling and use of the molecule confirms the not spontaneous ignition property.

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 it is not classified as a substance which in contact with water may react to emit flammable gases and an experimental determination according to the EC test guideline A.12 do not need to be performed.
