Description of key information

N-[3-(dimethylamino)propyl]-C12-18(even numbered)-alkylamide is not inhibitory to micro-organisms at a concentration of 2 mg/L.

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
2 mg/L

Additional information

Ready biodegradability of N-[3-(dimethylamino)propyl]-C12-18(even numbered)-alkylamide has been performed according to the OECD guideline 301 D “Ready biodegradability - Closed Bottle Test” and GLP requirements (Van Ginkel, 2009). Under the test conditions, the percentage of biodegradation of 2 mg/L of test item reached 85 % at the end (28 days) of the test. Thus it can be concluded that the test substance is not inhibitory to micro-organisms at 2 mg/L.
