Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Phototransformation in air

After evaporation or exposure to the atmosphere, the substance is expected to photodegrade rapidly by reaction with OH-radicals with a half-life of 5.1 hours (24 -h day, 500000 OH/cm3; EPIWin, AOP v1.92; BASF, 2014).



In accordance with column 2 of REACH Annex VII, the study does not need to be performed if the substance is readily biodegradable or inorganic. Propylenediamine is readily biodegradable; therefore a study is not required. Further, according to Kollig et al. (1993), Boethling & Mackay (2000), hydrolysis is not expected to be a relevant degradation process due to the absence of hydrolysable groups.


The substance is readily biodegradable according to OECD criteria.


Significant accumulation in organisms is not to be expected.

Adsorption / desorption:

The adsorption of the substance to the solid soil phase is not to be expected.

Henry's Law constant:

The substance will not evaporate into the atmosphere from the water surface.

Distribution modeling:

Over time, the substance will preferentially distribute into the compartment water (97.3%).
