Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Phototransformation in air

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



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



Ethylene glycol is readily biodegradable according to OECD criteria.



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


Adsorption / desorption

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


Henry's Law constant

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


Environmental distribution modelling

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