Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Short-term toxicity to aquatic invertebrates
Administrative data

Description of key information
No data are available on the acute toxicity of DEA acetate to aquatic invertebrates, but two structurally-related compounds have been subject to 48-hr tests on freshwater Daphnia magna. In each case, the 48-hr EC50 was greater than 100 mg/L.
Key value for chemical safety assessment
Fresh water invertebrates

- Effect concentration:
- 100 mg/L
Additional information
No data were available on DEA acetate, but two reliable guideline studies have been carried out on structurally-related compounds.
Daphnia magna were treated with RA1 in a 48-hr static test. A nominal concentration of 100 mg/L (125 mg/L including 20% water) was tested. No immobilisation or mortalities were seen over the test period. The 48-hr NOEC was 100 mg/L, and the 48-hr EC50 was >100 mg/L (Peither, 1999).
RA2 has been tested in a 48-hr semi-static test on D. magna. Nominal concentrations of up to 100 mg/L were used. No mortalities or toxic effects were observed. The 48-hr NOEC was 100 mg/L and the 48-hr EC50 was >100 mg/L (Grutzner, 1997b).
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.
