Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Self-ignition: 280.5 °C.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 280.5 °C
Additional information
The autoflammability of the substance was performed according to the EU Method A.16 (Relative Self-Ignition Temperature for Solids).
The self-ignition was defined at 280.5 °C.
The Test Method is defined in the Regulation 440/2008, method A.16.
Handling experience with the substance 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 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;
-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 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 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 could be considered as a substance which in contact with water may not react to emit flammable gases.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
