A spray delivery system including a sprayable active agent composition housed within a container is provided that can be used in the treatment of various skin conditions. The composition includes a hydrofluoro-based propellant, a carrier fluid, and active agent particles, and has a viscosity ranging from about 500 centipoise to about 10,000 centipoise. The container includes a dip tube; a valve assembly that includes a valve body, a stem comprising a stem orifice, and a vapor tap; and an actuator. The dip tube is coupled to the actuator by the valve assembly, and the actuator is depressed to dispense the emulsion. By selectively controlling the components and viscosity of the composition and the dimensions of the container components, the active agent particles resist settling so a substantially homogeneous distribution of the particles is maintained. Thus, the composition can be evenly dispensed from the container as a fine mist without clogging.
A spray delivery system comprising a sprayable composition having a viscosity ranging from 1,000 centipoise to 10,000 centipoise, wherein the composition comprises a hydrofluoro-based propellant, a carrier fluid, a non-crosslinked dimethicone polyol, a sorbitan fatty acid ester, and an octyldodecanol, wherein the non-crosslinked dimethicone polyol, the sorbitan fatty acid ester, and the octyldodecanol are nonionic lipophilic emulsifiers each having a hydrophilic to lipophilic balance (HLB) value between 2 and 8:
