Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Non autoflammable

Key value for chemical safety assessment

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, for the substance 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 liable to self-heat by reaction with air and without energy supply.

In addition, the substance is expected to be 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 cannot be classified as a substance that in contact with water may react generating flammable gases.
