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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 BCF/BAF of the test substance 2 -butyl octanoic acid indicate not a high potential for bioaccumulation in aquatic organism.
Additional information
The low BCF/BAF values of the similar substances n-undecanoic acid, 2 -methyl decanoic acid, 2 -ethyl nonanoic acid, 2 -propyl octanoic acid and 2- butyl heptanoic acid support this approach.
Aliphatic acids play an extremely important role as an energy source, particularly in higher animals and plants, and the absorption, distribution, metabolism and elimination of aliphatic acids have been well understood for years (Lehninger 1970, Nelson and Cox, 2008). In vertebrate animals, aliphatic acids are rapidly absorbed through the gut and transported throughout the animal body by serum albumin. Aliphatic acids are converted to acyl-CoA derivatives (aliphatic acyl-CoA), transported into cells and mitochondria by specific transport systems and then completely metabolized to acetyl-CoA or other key metabolites by catabolic enzymes that efficiently remove 2-carbon units from the aliphatic acyl-CoA molecule (β-oxidation pathway).
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.
