Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Toxic effects on sediment dwelling invertebrates are not expected
Key value for chemical safety assessment
Additional information
No studies on long-term sediment toxicity are available for this substance. Due to the estimated log Koc of 1.02 (KOCWIN v2.00, estimated from log Kow of 1.57) a low adsorption to sediment is indicated. In addition, azelaic acid has been shown to be readily biodegradable, hence it can be assumed that they will be completely biologically degraded within the sediment transport process. Therefore, no chronic exposure of sediment dwelling organisms is expected. Furthermore, fatty acids occur in sediment and soils naturally, are part of physiological pathways and can be used as energy source. Thus, toxic effects caused by azelaic acid are implausible.
In conclusion, due to a) an estimated log Koc of 1.02, b) the lack of chronic exposure and c) fatty acids are part of physiological pathways, toxic effects on sediment dwelling invertebrates are not expected.
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.
