Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

Handling experience with the substance indicates stable behavior 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 that a potential for spontaneous ignition is not expected:

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

- the substance 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 substance is 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 very 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 is not to be 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 needs to be performed according to the REACH Regulation.
