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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Key value for chemical safety assessment
- EC10 or NOEC for microorganisms:
- 1.8 mg/L
Additional information
The ready biodegradability was assessed in a study according to the OECD guideline 301 D “Ready biodegradability - Closed Bottle Test” (Gancet 2009). In the toxicity control the non-adapted activated sewage water treatment plant micro-organisms were exposed to 1.8 mg/L propoxylated N-tallow alkyltrimethylenediamines. There were no signs of inhibition. It is in agreement with ECHA (2008) Guidance, Chapter R.7b to use this type of information for the assessment of toxicity to micro-organisms. Chapter R.10.4.2 allows the derivation of the PNECstp on the basis of NOEC in biodegradation tests using applying an AF of 10 as no dose response curve is investigated in biodegradation studies and thus no corresponding LOEC exist.
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.
