A sprayable emulsion is provided. Emulsions can be used to treat a variety of skin conditions. Emulsions include hydrofluoro-based propellants, emulsification systems, oily, water and active agent particles. In addition, the emulsification system comprises at least one nonionic emulsifier. The emulsion has a viscosity ranging from about 500 centipoise to about 10,000 centipoise and a hydrophilic to lipophilic balance (HLB) value from about 2 to about 12. The inventors have found that by selectively controlling the nature of the emulsification system and the viscosity of the emulsion, the active agent particles have a settling resistance so that a substantially homogeneous distribution of active agent particles is maintained, ≪ / RTI > |
