Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

Rate constant with hydroxyl radicals: 0.44 * 10^-12 cm3/(molecule*sec)

Key value for chemical safety assessment

Half-life in air:
36 d

Additional information

A rate constant with hydroxyl radicals of 0.44 * 10^-12 cm3/(molecule*sec) was derived for Epichlorohydrin at 298 °K. With a seasonally and diurnally 24 hour averaged hydroxyl radical concentration of 0.5*10^6 molecules/cm3 the half-life in the atmosphere can be estimated to be 36.5 days.
