Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Tallow tripropylenetetramine (composition of the oleyl-alkyl chain is specified by Karleskind (1996)) is an alkyl polypropylene polyamine. Only one valid ready biodegradability test result for alkyl polypropylenepolyamines is available because these substances are very toxic to microorganisms. Nevertheless all aspects important to show non persistence of oleyl tripropylenetetramine are available i.e. 1) ultimate (complete) biodegradation (demonstrated in (S)CAS tests and through read across) 2) high rates of degradation (through read across with coco dipropylenetriamine) and 3) occurrence of competent microorganisms in unacclimated ecosystems (through read across with coco dipropylenetriamine) are fulfilled. Tallowltripropylenetetrariamine is at present viewed as not persistent.
