Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 test item Fatty acids, tall-oil- reaction products with diethylenetriamine (EFKA K 089) is an UVCB substance consisting of substructures with different alkyl chains. Each substructure has its own bioaccumulation potential in the environment. Therefore, each substructure was modelled for its bioaccumulation potential by using the QSAR tool Catalogic 5.12.1, BCF base-line model v. 02.09, from the OECD toolbox. Substructures were modelled based on smiles code of the substructures given in Chap. 1.1 identification.
The highest log BCF determined for the substructure 1 was 2.41 corresponding to a BCF of 257, whereas all other log BCF values ranged at 0.87 corresponding to a BCF value of 7.4. According to the modelled log BCF, respectively the BCF values, there is no indication that the test item with its substructure has no significant tendency to accumulate in organisms.

Additional information
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.
