Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 partition coefficient n-octanol / water (Kow) of 1,3,3-trimethyl-N-(2-methylpropylidene)-5-[(2-methylpropylidene)amino]cyclohexanemethylamine was determined according to OECD guideline no. 117 [2004] and EU test method A.8 [2008] with the HPLC method. The result was: 
Partition coefficient n-octanol / water (Kow) at 25 °C: Kow = 158489  /  log Kow = 5.2 (at pH 7.5).

Key value for chemical safety assessment

Additional information

There are no data available on the bioaccumulation potential of 1,3,3-trimethyl-N-(2-methylpropylidene)-5-[(2-methylpropylidene)amino]cyclohexanemethylamine in aquatic organisms. As a first screening tool the log Kow is used. The value is 5.2 which indicates a potential for bioaccumulation. In contrary the rapid hydrolysis of the substance suggests that such partitioning is of low relevance for the environmental distribution and fate of the substance.
