Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

REACH regulation requires an assessment of the hydrolytic stability of the substance as part of the environmental stability hazard assessment; further studies can be provided if necessary. The rate of hydrolysis of OFPMA as a function of pH was determined according to OECD Guideline 111 and was found to be fast, with half lives of 2.7 days for pH 4, 4.1 days for pH 7, and 3.9 hours for pH 9 at 20°C, using second order kinetics. The products of the hydrolysis were confirmed with NMR analysis to be octafluoropentanol and methacrylic acid. Investigation into further forms of environmental stability are not required.
