Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 n-octanol/water partition coefficient of DETDA at 25ºC, expressed as the logarithm (base 10), was determined to be 1.38 ± 0.019 (n = 6, CV = 1.4%). The measured pH value of the aqueous phase was 8.53

Key value for chemical safety assessment

Log Kow (Log Pow):
at the temperature of:
25 °C

Additional information

Currently for the partition coefficient of the testing material, 2 experimental studies are available. Both studies have been performed using the shake flsak method (OECD guideline N°107). The values are comparable and are the following:

* Log Kow = 1.17 (Report 401397)

* Log KOW = 1.38 (Report 471C-143)

For the dossier, the most recent value has been taken.
