Phototransformation in air

After evaporation or exposure to the air, diethylene glycol will be slowly degraded by photochemical processes.



Based on the structural properties and the rapid biodegradability of diethylene glycol, hydrolysis is not expected to be an important fate process.



Diethylene glycol is readily biodegradable according to OECD criteria.



Bioaccumulation of diethylene glycol in aquatic organisms is not to be expected.


Adsorption / desorption

Adsorption of diethylene glycol to the solid soil phase is not to be expected.


Henry's Law constant

From the water surface, diethylene glycol will not evaporate into the atmosphere.


Environmental distribution modelling

Over time, the substance will preferentially distribute into the compartment water (100%).
