This invention relates to compositions containing lower (C1-C4) alcohol and a polymeric fluorosurfactant formulated for being dispensed as a foam product. More particularly, the invention relates to improved compositions formulated with polymeric fluorosurfactants with pendant perfluoroalkyl side chains of a fully fluorinated chain length of C1-C7. The compositions also relate to use for personal care, such as skin sanitizing and cleansing.
