Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
No data are available on the acute toxicity of DEA acetate to fish, but three structurally-related compounds have been subject to 96-hr tests on freshwater species (carp, zebrafish and rainbow trout). In each case, the 96-hr LC50 was greater than 100 mg/L.
Key value for chemical safety assessment
Fresh water fish

Additional information
No short-term fish toxicity studies were available on DEA acetate, but three reliable guideline studies are available on structurally-related compounds.
A 96-hr LC50 of >100 mg/L was seen for TEA acetate in a static test on carp (Cyprinus carpio). No mortalities or clinical signs were seen in fish exposed to this limit concentration (Bouwman, 2010a).
Another static test exposed zebrafish (Brachydanio rerio) to RA1 at a nominal concentration of 100 mg/L (125 mg/L including 20% water). No mortality or signs of toxicity were seen in treated fish. The 96-hr LC50 was therefore determined to be >100 mg/L (Peither, 2000a).
The acute toxicity of RA2 has been assessed in a semi-static test on rainbow trout (Oncorhynchus mykiss), using a nominal concentration of 120 mg/L. No toxic effects were observed. The 96-hr LC50 was therefore >120 mg/L (Grutzner, 1997a).
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.
