Abiotic degradation

Abiotic degradation is of limited relevance for the environmental fate of amides, C12-18 (even numbered) and C18-unsatd., N,N-bis(hydroxyethyl) because the substance is readily biodegradable.

Biotic degradation

Amides, C12-18 (even-numbered) and C18-unsatd., N,N-bis(hydroxyethyl) is readily biodegradable, as shown in one OECD Guideline screening study (see Table 10). Furthermore, the structurally similar amides, C8-18 and C18-unsatd., N,N-bis(hydroxyethyl) has also been shown to be readily biodegradable in two independent OECD Guideline screening studies (Table 10). The substance istherefore unlikely to persist in the aquatic or terrestrial environment.

Biodegradation in water and sediment

In accordance with Annex IX Column 2 adaptation of REACH, testing is not required, since amides, C12-18 (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, C12-18 and C18-unsatd., N,N-bis(hydroxyethyl) is readily biodegradable.
