Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
Description of key information
Not readily biodegradable: 1% (test material analysis) and 3 - 7% (oxygen consumption, DOC removal) in 28 days (OECD 301A, 301C)
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
Two studies investigating the ready biodegradability of triallyl isocyanurate are available. The key study (2003-0176-DGO) was carried out according to OECD 301A and GLP and used domestic activated sludge. Based on DOC removal, triallyl isocyanurate attained 7% degradation. A supporting study used a mixture of sewage, soil and water as inoculum in a modified MITI-test according to OECD 301C and GLP (98-0398-FGO). In this test, triallyl isocyanurate attained 3% degradation based on O2 consumption and DOC removal, respectively, and 1% degradation based on the analysis of the test material. Both tests included valid parallel analyses of a reference substance. Hence, triallyl isocyanurate can be classified as not readily biodegradable according to the strict OECD criteria.
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.
