다양한 피부 병태의 치료에 사용될 수 있는, 용기 내에 하우징된 분무가능한 활성제 조성물을 포함하는 분무 전달 시스템이 제공된다. 조성물은 히드로플루오로-기재의 추진제, 캐리어 유체, 및 활성제 입자를 포함하고, 약 500 센티포아즈 내지 약 10,000 센티포아즈 범위의 점도를 갖는다. 용기는 딥 튜브; 밸브 바디, 스템 오리피스를 포함하는 스템, 및 증기 탭을 포함하는 밸브 어셈블리; 및 작동기를 포함한다. 딥 튜브는 밸브 어셈블리에 의해 작동기에 커플링되고, 작동기가 눌러져 에멀젼을 분배한다. 조성물의 성분 및 점도, 및 용기 부품의 치수를 선택적으로 제어함으로써, 활성제 입자가 침강 저항성을 가져서, 실질적으로 균질한 분포의 입자가 유지된다. 따라서, 조성물이 클로깅 없이 미세 미스트로서 용기로부터 균일하게 분배될 수 있다. 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.
