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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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