Abstract
A sprayable zinc oxide composition is provided. The sprayable zinc oxide composition can be used in the treatment of various skin conditions. The sprayable zinc oxide composition includes zinc oxide particles and a fluoro-olefin propellant. The present inventors have found that by selecting a propellant having a certain specific gravity, vapor pressure, and molecular weight, and by controlling the viscosity of the various components of the composition, the resulting zinc oxide composition resists settling such that a substantially homogeneous distribution of zinc oxide particles is maintained and can be evenly sprayed onto a surface without running once applied.
