Additional information

Phototransformation in air

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



In contact with water ethylene oxide will hydrolyse slowly.


Ethylene oxide is readily biodegradable according to OECD criteria.



Bioaccumulation of ethylen oxide in aquatic organisms is not to be expected. 

Adsorption / desorption

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


Henry's Law constant

From the water surface, ethylene oxide will evaporate slowly into the atmosphere.


Environmental distribution modelling

Over time, the substance will preferentally distribute into the compartment water (92.3%) and air (7.75%).
