Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 valid short-term toxicity data are available for aquatic invertebrates. The long-term EC50 for parental mortality/immobility will be used as a worst-case.

Key value for chemical safety assessment

Fresh water invertebrates

Fresh water invertebrates
Effect concentration:
566 µg/L

Additional information

From the figures of the branched triamine C12 (CAS no 2372 -82 -9) which were obtained by performing ecotoxicity tests in reconstituted lab water, it is clear that the long-term EC50 can be used as a worst-case short-term EC50 for daphnia. No valid short-term aquatic invertebrates data are available for branched triamine C16 -18 but as a worst-case the long-term EC50 will be used instead.
