Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Studies evaluating the short or long term toxicity of Diethylammonium chloride (CAS 660-68-4) to aquatic organisms are not available. Therefore short term toxicity data for all three trophic levels and chronic data for aquatic invertebrates and algae from the analogues substance N-ethylethanamine (CAS 109-89-7) were used for the environmental assessment.
Algae was the most sensitive tested organism with an ErC50 (96 h) of 20 mg/L and a ErC0 (96 h) of 2 mg/L, followed by aquatic invertebrates with an EC50 (48 h) of 56 mg/L and a NOEC (48 h) of 4.2 mg/L. No short term toxic effects were observed by the read across substance towards fish up to a concentration of 100 mg/L, when the pH was neutral.
Furthermore the substance is not considered toxic to microorganisms based on results of the read across substance (EC10 (30 min) > 1000 mg/L) and its rapid biodegradability.
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.
