Description of key information
Additional information
No biodegradation was observed in teither the inherent biodegradation or ready biodegradation tests that were conducted. It is concluded that triethylenetetramine, propoxylated (triethylene-tetramine adduct) is not readily biodgeradable in water.
The test material attained 8% biodegradation after 28 days. OECD Guideline No. 302B does not give any definitive pass levels for test material, however the “Summary of Considerations in the Report from the OECD Expert Group on Degradation and Accumulation” suggests that a figure of more than 20% biodegradation may be regarded as evidence for inherent, primary biodegradability. A figure of more than 70% mineralization may be regarded as evidence for ultimate biodegradation. The test material can therefore be considered not to have exhibited evidence of inherent, primary biodegradation under the experimental conditions employed in this study.
The simulation test for the biodegradation in water and sediment was not performed in accordance with column 2 of REACh (Regulation (EC) No 1907/2006) Annex IX, the simulation testing on ultimate degradation in surface water, and sediment simulation testing (required in section 9.2.1.2, and 9.2.1.4) do not need to be conducted based on the findings of the Chemical Safety Assessment; the substance does not fulfil classification criteria according to the applicable regulations and does not fulfil the criteria for vPvB or PBT.
The biodegradation in soil was waived in accordance with column 2 of REACh (Regulation (EC) No 1907/2006) Annex IX, the soil simulation testing (required in section 9.2.1.3) do not need to be conducted based on the findings of the Chemical Safety Assessment; the substance does not fulfil classification criteria according to the applicable regulations and does not fulfil the criteria for vPvB or PBT
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.
