Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
No auto ignition properties
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 does not melt up to 450 °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, self-ignition of the substance under O2 was assessed by 2 test conducted in 1974 and 1977. In the first test, no exothermic reaction was found up to 190 °C; in the second, no exothermic was found up to 240 °c and an exothermic reaction was reported starting at 250 °C. As no data on purity is available (commercial name: Telonecthorange AGT and Telonechtorange AGT 200 %, respectively), such data were only taken as a qualitative information, indicating a low auto-ignition potential.
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.
