Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Due to its composition, the partition coefficient n-octanol / water

(Pow) of the test item can only be estimated from the single

solubilities in n-octanol and in water.

As the test item shows complete miscibility with n-octanol and

with water at T = 23 °C and at T = 20.0 °C ± 0.5 °C, the estimation

of the Pow from the solubilities of the test item in water and

in n-octanol is also not possible.

An EPI Suite calculation for N1,N3-bis(3-aminopropyl)-2-methyl-cyclohexane-1,3-diamine and N1,N3-bis(3-aminopropyl)-4-methyl-cyclohexane-1,3-diamine results in a log Kow of 0.46 at 25 °C for both molecules.
