Description of key information
The substance is readily biodegradable (according to OECD criteria).
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
The ready biodegradability of 3-dimethylaminopropan-1-ol was tested in a guideline study conducted in compliance with OECD 301 A. The substance was biodegraded by 99% after 28 days by non-adapted activated sludge (BASF AG, 2005; report no. 21G0408/053145).
The key data are supported by the results of a guideline study according to OECD 302 B. Based on DOC, biodegradation of the substance was found to be 99% after 9 days using industrial activated sludge as inoculum (BASF AG, 1981).
In addition, Eide-Haugmo et al. (2012/2009) performed two guideline studies according to OECD 306 using natural seawater as inoculum. The substance turned out to be not readily biodegradable under marine conditions (15.6% after 28 d, based on O2 -consumption).
In conclusion, the substance is readily biodegradable (according to OECD criteria).
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.
