Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The substance is an UVCB. Most bioaccumulation tests are difficult to apply to UVCB substances and standard tests for this endpoint are intended for single substances rather than complex substances such as the substance to be registered. Estimates of the Kow values for the individual components may be used to assess the bioaccumulation potential of the substance. Measured log Kow values are available for the substance indicating that the majority of the constituents have log Kow values > 6.5. To get a hint of the bioaccumulation potential, the bioconcentration factor BCF of Fatty acids, tall-oil, reaction products with formaldehyde and Z)-N-9-octadecenyl-1,3-propanediamine (CAS# 68911-83-1) was calculated using EPIWIN v4.10, BCFBAF v3.01. The calculation yielded BCF values of 6.17 L/kg wet-wt (based on an estimated log Kow of 13.8) and 381 L/kg wet-wt (based on a measured log Kow of 6.5) respectively. These results indicate a low bioaccumulation potential.
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.
