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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
Studies with fish, daphnids and algae as well as with aquatic microorganisms are available and thus, the PNECs are based on the test results and assessment factors recommended in the Technical Guidance Document (ECHA, 2008) have been applied. For the compartments sediment and soil, no studies have been conducted and the PNECs have been calculated using the Equilibrium Partitioning Method as screening values. The outcome of the Chemical Safety Assessment indicates no need for testing on sediment or soil dwelling organisms as the PEC/PNEC ratios does not exceed the trigger value of 1. Additionally, triallyl cyanurate has only low adsorbing potential and a study with sediment dwellers is not triggered.
The PNEC oral is derived from a toxicological endpoint as the toxicity towards birds has not been tested.
Conclusion on classification
Fish was found to be the most sensitive aquatic species. The LC50 (96 h) is 7.05 mg/L and the substance is not readily biodegradable thus, triallyl cyanurate is classified according to EU classification as R51/53 and according to GHS as chronic category 2.
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.
