Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
DEAPA can be considered as slightly harmful to microorganisms.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 100.5 mg/L
Additional information
Diethylaminopropylamine (DEAPA) toxicity to Pseudomonas putida has been investigated according to DIN 38412, part 8 (BASF, 1987). EC50_17h (growth inhibition) was determined to be 100.5 mg/L. In addition, DEAPA toxicity to microorganisms has been investigated according to OECD TG 209 (BASF, 2009). EC50 was determined to be higher than 1000 mg/L but the test solutions were neutralised. The result of the study suggests that the toxicity of DEAPA to microorganisms is related to the increase of the medium pH but not to a specific mode of toxic action.
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.
