Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
The registered substance, Amines, N-(C16-18 and C18-unsatd. alkyl)trimethylenedi-, diacetates is considered readily biodegradable (CAS 1313206-64-2) according to OECD guideline 301D test and GLP requirement. The validity criteria were fulfilled. The test substance can be considered as readily biodegradable.
Based on the available studies on biodegradation, all alkyl 1,3 -diaminopropanes (C10 - C18) are also considered to be readily biodegradable.
A waste water treatment simulation test was performed with amines, N-C16-18-alkyl (even-numbered) propane-1,3-diamine (133779-11-0). 99.4% removal was observed using specific chemical analyses (LCMS/MS) of the effluent during day 56 to 60 (n=5). In addition, sorption to sludge was measured and this accounted for 4.1% of the total removal which means that 95.3% was removed by biodegradation.
Simulation testing of ultimate degradation in surface water, in sediment and in soil are not required considering that the susbtance is readily biodegradable (according column 2 of REACH Annex IX. 9.2). Therefore in these circumstances, the simulation test will provide little additional information since rapid mineralisation in the environment is already assumed.
No simulation tests for degradation rates under environmental conditions are available, therefore the default values suggested in the REACH guidance may be used.
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.
