Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- 150 mg/L
- EC10 or NOEC for freshwater algae:
- 52 mg/L
Additional information
The assessment of the toxicity of 2-aminoethyldiisopropylamine (CAS 121-05-1) to aquatic algae and cyanobacteria is based on a read-across approach to the structurally analogous substance ethyldiisopropylamine (CAS 7087-68-5).
A study on growth inhibition of the freshwater algae Pseudokirchneriella subcapitata, exposed to the analogue ethyldiisopropylamine (CAS 7087-68-5) for 72h, was performed according to OECD TG 201. The pH of the stock solution was adjusted to 8 in order to limit the pH increase during the test. Based on measured test concentrations the 72-h ErC50 was determined to be 150 mg/L (72-h ErC10 = 52 mg/L).
Based on the available read-across data, 2-aminoethyldiisopropylamine is assessed to be with high probability acutely not harmful to aquatic algae and cyanobacteria.
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.
