Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Abiotic degradation

It is assumed that abiotic degradation is of limited relevance for the environmental fate of amides, C16-18 (even-numbered) and C18-unsatd., N,N-bis(hydroxyethyl). Furthermore, because it is readily biodegradable, data on hydrolysis is not required in accordance with Annex IX column 2 adaptation of REACH.

Biotic degradation

Two OECD guideline compliant biodegradation studies have shown amides, C16-18 (even-numbered) and C18-unsatd., N,N-bis(hydroxyethyl) to be readily biodegradable with percentage degradation ranging from 60-62% in 28 days. An ultimate biodegradation study conducted with amides, C16-18 (even-numbered) and C18-unsatd., N,N-bis(hydroxyethyl)) has shown 95.46% degradation in 30d indicating a rapid biodegradation. Overall, based on the available information, the substance is likely to degrade 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 environments.

Biodegradation in water and sediment

In accordance with Annex IX column 2 adaptation of REACH, testing is not required since amides, C16-18 (even-numbered) and C18-unsatd., N,N-bis(hydroxyethyl) is readily biodegradable .

Biodegradation in soil

In accordance with Annex IX column 2 adaptation of REACH, testing is not required since amides, C16-18 (even-numbered) and C18-unsatd., N,N-bis(hydroxyethyl) is readily biodegradable.
