- readily biodegradable
Additional information
Regarding biodegradation in water no conclusion could be obtained based on the existing data for triethylamine. The biodegradation test performed with triethylamine (NITE, date unknown) proves that the substance is biodegradable. However, an interpretation of the results is not possible due to limited information regarding the test method. Therefore, a study of the substance tripropylamine was included to fulfill the intention of read-across (BASF AG, 1990). This was a possible option due to the fact that both substances possess a similar chemical structure. With the same intention another read-across to tributylamine was performed (Muckle, 2010). Tributylamine was found to be readily biodegradable.
The EU commission working group on classification and labelling of dangerous substances decided to regard triethylamine as readily biodegradable (1995). The proposal for classification and labelling was N; R51-53. Although some ambiguous experimental data were available, the members of the working group agreed at least in the second meeting not to classify the substance as dangerous for the environment.
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.
