Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The substance is thermally instable under the test condition.
SADT for a non-stabilized item, isolated 25 m³-tank: 50 °C
SADT for a stabilized item, isolated 25 m³-tank: 100 °C
AZT24: 87 °C (corresponding to AZT72 of 65 °C)
Additional information
SADT was determined according to UN-RTDG MTC Test H.2 for an isolated-25 m³ tank using an adiabatic storage test. AZT24 was determined by an adiabatic calorimeter test.
Triallyl isocyanurate undergoes exothermic decomposition process at approximately 128 °C (DSC) or 140 °C (adiabatic calorimeter), which can lead to higher temperature and thermal explosion. Violent ruture of contains may occur at temperatures generated.
Justification for classification or non-classification
Self-heating property: With a melting point of 24.8 °C, triallyl isocyanurate is considered not self-heating.
Self-reactive property: Triallyl isocyanurate undergoes exothermal decomposition at approximately 128 °C (DSC). SADT are 100 °C for stabilised test item and 50 °C for unstabilised item respectively for an isolated 25 m³-tank, which correspond to approximately 27 tons of test items (density 1.1 d/mL). Under the test condition, SADT less than 75 °C for a 50 kg package is not expected. Thus, triallyl isocyanurate does not need to be classified into the hazard class of self-reactive substance according to CLP.
A thermal stabilisation measures shall be implemented for transport of unstabilized triallyl isocyanurate only in high volume.
Corrosive to metals: Triallyl isocyanurate has not to be classified as metal corrosive.
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).
