Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Soluble fatty acids are readily biodegradable which was demonstrated in biodegradation tests according to OECD-guidelines. In addition degradation studies cited in the Draft Assessment Report (DAR) for Fatty Acids (C7-C20) (Volume1, 2008) DT50 values of 1.5 to – 3 days were reported, indicating rapid primary degradation of fatty acids by microbial organisms in the soil environment.
Further, in the same DAR low toxicity of a fatty acid formulation was demonstrated in several tests on soil macroorganisms, terrestrial non-target arthropods and terrestrial plants (DAR, Volume 1, 2008). These studies prove the negligible effects of fatty acids to terrestrial macroorganisms. Furthermore, fatty acids occur in soils naturally, are part of physiological pathways and can be used as energy source. Thus, low toxicity is expected for terrestrial organisms exposed to the test substance.
In conclusion, due to a) the rapid degradation of fatty acids, b) the use as energy source, and c) tests available for a fatty acid formulation toxic effects to terrestrial organisms 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.
