Description of key information
There is one acute test result available for coco based primary fatty amine ethoxylates (old CAS no 61791-31-9) and two for the pure C12 alkyl chain (CAS no 1541-67-9) primary fatty amine ethoxylate.. Like for the acute fish studies, most of the short-term daphnia tests were conducted in a period when no reliable specific method of analyses was available. Hence, most of the tests were considered to be valid with restrictions and are because of the availability of better data just used to complete the ecotoxicity picture of this substance. Based on the limited reliability of the acute studies it was decided to perform a higher tier long-term (21 d) invertebrate study with 2,2'-(C12-18 evennumbered alkyl imino) diethanol. The 21d EC50 value from this study is used as a worst-case for the short term hazard assessment.

Besides to the results of the recently performed long-term study, the available acute daphnia toxicity data are presented in the table There is one acute test result available for coco based primary fatty amine ethoxylates(old CAS no61791-31-9) and two for the pure C12 alkyl chain(CAS no 1541-67-9) primary fatty amine ethoxylate..Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
