Description of key information
Amides, C18-unsatd., N-[3-(dimethylamine)propyl] is considered not harmful to activated sludge.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 192 mg/L
- EC10 or NOEC for microorganisms:
- 80 mg/L
Additional information
The toxicity to activated sludge was determined in accordance with OECD Test Guideline 209, and in compliance with the OECD principles of Good Laboratory Practice. The test is valid as shown by the EC50 of the reference compound, 3,5- dichlorophenol (8 mg/L) and the control respiration rates which are within 15% of each other. The toxicity of Amides, C18-unsatd., N-[3-(dimethylamine)propyl] to activated sludge was determined at a contact time of 3 hours, using various concentrations of the test substance. The inhibitory effect of Amides, C18-unsatd., N-[3-(dimethylamine)propyl] at a particular concentration is expressed as a percentage of the two controls. The EC50 for activated sludge after 3 hours contact time is 192 mg/L with 95% confidence limits of 115 and 407 mg/L. The EC10, EC20 and EC80 are 80, 108 and 343 mg/L, respectively.
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.
