Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Results and discussion

Any other information on results incl. tables

Several studies suggest the following mechanism for the microbial degradation of VC:

VC ----(oxidation by methane-monooxygenase)---->
 
chloroethylene oxide -----(rearrangement)------>

chloroacetaldehyde ---------(oxidation)-------->

chloroacetate ---(hydrolytic dehalogenation)--->

glycolate (------> normal cellular metabolism)
