Description of key information
The key value for chemical safety assessment is the result of an experiment with neutralized test substance (BASF AG, 1989).
Key value for chemical safety assessment
- EC50 for microorganisms:
- 1 000 mg/L
Additional information
The toxicity to microorganisms of TEA was tested by BASF AG (1989) in accordance with DIN 38412, Part 8 (Pseudomonas Zellvermehrungshemm-Test). The test organism was Pseudomonas putida and exposure duration of 17 h was reported. The nominal effective concentrations (ECx) were based on growth inhibition. Results with non-neutralized triethylamine were: EC10 = 71 mg/L, EC50 = 95 mg/L, and EC90 = 120 mg/L. Neutralized test substance testing gives as result an EC50 value greater than 1000 mg/L.
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.
