Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Phototransformation in air
After evaporation or exposure to air, the test item (represented by its branched and linear isomers) will be rapidly degraded by photochemical processes.
Hydrolysis
Hydrolysis is not expected due to the absence of hydrolysable groups.In addition, the substance is not soluble in water.
Biodegradation
The substance is not readily biodegradable (according to OECD criteria).
Bioaccumulation
Significant accumulation of the substance (represented by by its branched and linear isomers) in organisms is not to be expected.
Adsorption
Adsorption of the substance (represented by its branched and linear isomers) to the solid soil phase is expected.
Henry's Law constant
The substance will slowly evaporate from the water surface into the atmosphere. However, as it will be completely ionized under environmentally relevant conditions, the evaporation potential is most likely overestimated.
Distribution modelling
Over time, the substance will distribute mainly into the compartments soil (49.5%) and sediment (50.1%).
Additional information
Di-tridecylamine, branched and linear (CAS 101012-97-9) is a mixture of (predominantly) di-alkyl amines with varying alkyl-chain length in a range between C24 and C27. The main fraction consists of isomers of di-tridecylamines (C26H55N). Secondary fractions were detected to have chain lengths of C13 and C39. The following structures and relative fractions were proposed:
