Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
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. Many dyes were tested and does not show low auto-ignition temperature. The substance decomposes before melting from 272 °C and is not flammable. 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 is considered to be not classified as a substance that in contact with water may react generating flammable gases.
Moreover, in order to support these consideration, an experimental study on a very similar substance was considered. The substance results to be not autoflammable under the test conditions.
Based on the Expert judgement and on the results of the experimental study, the substance is considered to be not autoflammable.
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).
