Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Accumulation in organisms not to be expected.

Key value for chemical safety assessment

Additional information

(2-hydroxyethyl)ammonium nitrate is completely soluble in water and dissociates to (2- hydroxyethyl)ammonium and nitrate ions.

Since no studies on the bioaccumulation potential of (2 -hydroxyethyl)ammonium nitrate are available, the bioaccumulation has been assessed with the substance’s dissociation products.

2 -aminoethanol is not expected to accumulate in organisms based on its logPow of -1.91.

As nitrates are biodegradable and very soluble in water, they are not expected either to bioaccumulate in aquatic organisms.

Conclusively, (2 -hydroxyethyl)ammonium nitrate is not expected to bioaccumulate in aquatic organisms.
