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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The substance is not considered to be bioaccumulative.
Key value for chemical safety assessment
Additional information
Since Fatty acids, C8-18 and C18-unsatd., reaction products with diethanolamine and propylene oxide (CAS No. 1000817-22-0) is a surface active substance the log Pow cannot be scientifically determined and thus this screening parameter cannot be used to assess the bioaccumulation potential of the substance.
However, based on the following observations it can be concluded that the test substance is not bioaccumulative in aquatic/terrestrial organisms:
1) The substance is readily biodegradable which indicates that the test substance will rapidly metabolized in organisms. This was also shown by Weisbrod (2005, on behalf of the Industry Coordinating Group, ICG) for linear ethoxylated aliphatic alcohols, which clearly demonstrate that these aliphatic substances are not bioaccumulative.
2) Long-term toxicity tests show effect values in the same range than the acute toxicity tests indicating no increasing concentrations of the substance in aquatic organisms over time.
3) No mortality was observed in a short-term toxicity test with earthworms performed according to OECD guideline 207.
Based on these facts it is concluded that bioaccumulation of the test substance is unlikely and due to animal welfare reasons no animal tests according to OECD 305 are deemed necessary.
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.
