Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
For tetramine di-C16 -C18 acute aquatic toxicity results are available for fish (96h LC50>0.272 mg a.i./L, geometric mean measured), daphnia (48h EC50 = 0.244 mg a.i./L, geometric mean measured) and algae (72h ErC50 = 0.23 mg a.i./L mean measured initial). For the derivation of the PNEC of tetramine di-C16 -C18 for the aquatic compartment two long term key endpoints are available. The algae test gave an ErC10 of 0.050 mg a.i./L and the long term daphnia test a EC10 for reproduction of 0.148 mg a.i./L.
For the derivation of the PNECstp of tetramine di-C16 -C18 an OECD 209 test has been performed. The test substance caused no inhibiting effects on activated sludge of a municipal sewage treatment plant at the limit test substance concentration o 1000 mg/L. No nitrification inhibition was observed at 1000 mg/L in the preliminary test and this endpoint was therefore not evaluated in the definitive test.
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.
