Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

TAED and DAED have low measured Log Kow of -0.1 respectively -1.0 (see Section 4.7 and AISE HERA TAED, 2002, attached as PDF in Section 13) which are far below the Log Kow cutoff 3 used in 1907/2006/EC Annex IX, Column 2, 9.3.2 and therefore a bioaccumlation potential for TAED and DAED is unlikely. In addition the US EPA BCFBAF program estimates for TAED and DAED a BCF of 3 L/kg which is very low and therefore it can be concluded that TAED and DAED have a low potential for bioaccumulation and secondary poisoning is not expected (no biomagnification through the food web).
