Description of key information
Additional information
Abiotic degradation
It is assumed that abiotic degradation is of limited relevance for the environmental fate of HE Rape Oil, reaction product with diethanolamine. Furthermore, the structural analogue amides, C18(unsatd.), N,N-bis(hydroxyethyl) is readily biodegradable (although does not fulfil the 10-day window criterion), and on this basis it is assumed that HE Rape Oil, reaction product with diethanolamine will also be readily biodegradable and as such data on hydrolysis is not required in accordance with Annex IX column 2 adaptation of REACH.
Biotic degradation
The read-across substance amides, C18(unsatd.), N,N-bis(hydroxyethyl) was readily biodegradable in two reliable guideline compliant studies. It showed about 70% degradation (although failing 10-d window) with 28d in an OECD 301D compliant study and about 95% degradation within 15d in a DIN 38 412 compliant study. Therefore, it can be reasonably assumed that amides , C18(unsatd.), N,N-bis(hydroxyethyl) degrades rapidly in the environment under aerobic conditions without formation of persistent degradation products. Consequently biodegradation under aerobic conditions is considered the most relevant fate process in the aquatic and terrestrial environment.
Biodegradation in water and sediment
In accordance with Annex IX column 2 adaptation of REACH, testing is not required on the basis that the structural analogue, amides, C18(unsatd.), N,N-bis(hydroxyethyl), is readily biodegradable and it is considered that the registered substance will be biodegradable also. Therefore this endpoint is not required for environmental fate and pathways.
Biodegradation in soil
In accordance with Annex IX column 2 adaptation of REACH, testing is not required on the basis that the structural analogue, amides, C18(unsatd.), N,N-bis(hydroxyethyl), is readily biodegradable and it is considered that the registered substance will be biodegradable also. Therefore this endpoint is not required for environmental fate and pathways.
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.
