ABSTRACT:
The invention provides a microemulsion that comprises from 0.1 to 99.0 parts by weight hydrofluoroether, from 1.0 to 99.9 parts by weight water, the sum of the parts of hydrofluoroether and water being 100 parts, and fluorinated surfactant. The microemulsions of the invention preferably contain a mixture of fluorinated surfactants and may also contain a non-fluorinated surfactant. The microemulsions of the invention may also further contain cosurfactant and/or cosolvent.
