Registration Dossier
Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 simulation tests for degradation rates under environmental conditions are available; therefore the default values suggested by the REACH guidance are used. For soil this is a half life value of 30000 days, this can be adapted if better soil data become available.
Key value for chemical safety assessment
Additional information
The Kpsoil was determined as 47000 L/kg. The suggested maximum half-life for a readily degradable substance with a Kpsoil in the range >10000 L/kg is 30000 days for soil (at 12 ºC). These values are considered as extremely conservative but in the absence of measured data will be used in the exposure assessment as a worst-case. The half-life of the bioavailable fraction of Fatty acids C18 unsat. diethylenetriamine imidazoline in the water phase of soils is expected to be in the order of a few days, which is based on experiments with dialkyldimethylammonium salts (van Ginkel et al, 2003).
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.
