Description of key information
Imidazoline DETA
Only one valid ready biodegradability test results for tall oil diethylenetriamine imidazoline is available because fatty amine derivatives are usually toxic and/or poorly available to micro-organisms. Fatty acids tall oil reaction products with diethylenetriamine tested in the presence of silica gel were biodegraded 24% at day 28 in the Closed Bottle. This test substance should therefore not be classified as readily biodegradable. In the enhanced (prolonged) Closed Bottle, test tall oil diethylenetriamine imidazoline was biodegraded 61% at day 60 (AkzoNobel, 2010). The biodegradation reached at the day 60 demonstrates that tall oil diethylenetriamine imidazoline is ultimately biodegradable and not persistent. The biodegradation and or hydrolysis products of tall oil diethylenetriamine imidazoline i.e. fatty acids and diethylenetriamine are readily biodegradable also proving the ultimate degradation of tall oil diethylenetriamine imidazoline.
Rosins
As a number of reliable studies are available for different members of this category indicating that the substances are readily biodegradable, members of the category Rosin, Hydrogenated rosin and their salts are considered readily biodegradable.
On the basis of the available data on the read across substances the substance is considered inherently biodegradable.
Additional information
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.
