Abstract

Foaming propellant compositions for use in hair mousse compositions described. These compositions contain hydrofluorocarbon 152A and a suitable hydrocarbon in a ratio of about 30 to 70; to about 50 to 50; more preferably about 40 to 60. These compositions comprise the hydrofluorocarbon 152A; and a hydrocarbon, selected from the group consisting of propane, isobutane, and n-butane in the above recited ratios. The above propellant mixture is about 4 to 9 wt. % of total foaming, hair care composition.
