Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
No hydrolysis study is required as the substance is ready biodegradable.
The biochemical degradability of the test substance Bis(hexamethylene)triamine at 293 K (20 deg C) was determined according to the OECD Guideline No. 301 D and to EC Method C.4 -E and compliant to GLP (reliability category 1).
Control- and blank-series without test substance were run simultaneously and the effectiveness of the inoculum was confirmed.
For the test substance, the following biodegradability was found:
1 % after 7 days,
49 % after 14 days,
100 % after 17 days,
100 % after 21 dayS,
100 % after 28 days.
Additionally, nitrate measurements in the 28 d samples confirmed a total nitrification of the test substance during the test period.
Therefore the test substance is classified as readily biodegradable according to the guidelines, meeting the 10 days window. Moreover it was found that an inhibitory effect of the test substance on the biochemical degradation of the reference substance at the concentration tested could not be excluded.
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.
