Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
For the aquatic compartment two long-term key studies are available not for Tetramine octadecenyl but for Triamine octadecenyl. The results of the Triamine octadecenyl will be used for Tetramine octadecenyl as a worst-case as the octadecenyl will be more bioavailable than the Tetramine octadecenyl. For Triamine octadecenyl, the chronic algae test gave a ErC10 of 0.518 mg/L and the chronic daphnia test a NOEC (reproduction) of 0.81 mg/L. For the effect assessment the EC10 for daphnia adult mortalilty of 0.577 mg/L will be used as a worst-case. Note that both chronic key studies are higher tier studies performed in river water. This means that for risk assessment the bulk approach should be applied i.e. both the effect and exposure assessment are based on the total concentration (dissolved and sorbed).
For the toxicity to micro-organisms an EC10 and EC50 of resp. 28 and 391 mg/L was observed after 3 h exposure to Tetramine octadecenyl.
For a comparison; For triamine octadecenyl an EC10 and EC50 of resp 18 and 115 mg/L was observed for the toxicity to micro-organisms after 3 h exposure. The observed higher toxicity of the triamine compared to the tetramine support the use of Triamine octadecenyl data for read across to Tetramine octadecenyl.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
