Epichlorohydrin hydrolyses within days to form 1-chloro-2,3-dihydroxypropane which is readily biodegradable. Epichlorohydrin has a low log Kow of 0.45 and therefore a low potential to sorb to particulate mater (sludge, soil or sediment) or to bioaccumulate in biota.

It has moderate water solubility and moderate vapor pressure. These properties result in a low potential to volatilize from water to air.

When released to air, the material will remain in air, with rapid dissipation occurring through advection and photochemical reaction. When released to water, the material will remain dissolved in water and will be rapidly degraded through biodegradation and hydrolysis reactions. When released to soil, the material will be primarily dissolved in soil pore water (groundwater), and will be rapidly degraded through biodegradation and hydrolysis reactions. Since the material is susceptible to destructive reactions such as indirect photolysis, biodegradation, and hydrolysis, this material is expected to be short-lived in the environment.
