Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The chronic NOEC in a Daphnia magna reproduction test was 0.85 mg/L.

Key value for chemical safety assessment

Additional information

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

Since there are no studies available on the aquatic toxicity of the test substance, published literature about the toxic effects of 2 -aminoethanol has been consulted alternatively.

The 21 day NOEC of 2 -aminoethanol (CAS 141-43-5) derived from toxicity testing with Daphnia magna was 0.85 mg/L (NITE, 1996).

Nitrate has not been tested for long-term effects on aquatic invertebrates because all data available concerning substances belonging to the nitrate category show a very low toxicity. In addtion, nitrates have a very high water solubility and their chemical properties do not indicate bioaccumulation. Therefore, the study is not considered necessary.
