Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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


After evaporation or exposure to air, the substance will be rapidly degraded by photochemical processes.



Due to structural properties, hydrolysis is not expected.



Based on a read-across approach from the structurally analogous compound 2-ethylcyclohexylamine (CAS 7003-32-9), the target substance 2,6-dimethylcyclohexylamine (CAS 6850-63-1) is assessed to be readily degradable (according to OECD criteria). 


Significant accumulation in organisms is not to be expected.


Transport and distribution:

Adsorption / desorption

Based on a pH corrected Koc calculated for charged molecule, adsorption to the solid soil phase is to be expected under environmentally relevant conditions. However, based on read-across data from the structurally analogous substance 2 -methylcyclohexylamine (CAS 7003-32-9) the chemical is assessed to be rapidly degradable (see IUCLID chapter 5.2).


Henry's Law constant

From the water surface, the uncharged substance will slowly evaporate into the atmosphere. However, under environmental relevant pH-conditions the molecule will almost entirely exist in its charged form in aquatic compartments (pKa 10.38). Hence, evaporation of the dissolved charged molecule may be overestimated using HENRYWIN v3.2.


Distribution modelling

Over time, the uncharged substance will preferentially distribute into the compartments water (98%) and air (2%).

However, since the substance will be ionized under environmentally relevant conditions, the distribution into water may still be underestimated.
