Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
A number of tests on inhibition of respiration according to OECD Guideline 209 were conducted.
The results of the respiration tests suggest that the toxicity of hydrogenated tallow amine and octadecenylamine to sewage sludge is much lower than that of coco and tallow amine. Regarding the test results with other organisms, similar toxicity of the compounds is expected. It can be assumed that the different results may be caused by different bioavailability of the test substances. As discussed earlier, bioavailability of the test substances is largely dependent on the method of preparation of the test medium, although there is no real explanation for the differences of individual tests. For the PNEC derivation, the lowest effect value found with coco amine as test substance are used (EC10 = 5.5 mg/L).
Key value for chemical safety assessment
- EC10 or NOEC for microorganisms:
- 5.5 mg/L
Additional information
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.
