Abstract
An aerosol actuator is provided having an inner actuator chamber, an inner actuator chamber outlet by which the composition to be dispensed may exit the inner actuator chamber, and a stem piece channel by which the fluid to be dispensed may enter the inner actuator chamber. The inner surface of the inner actuator chamber is mathematically continuous. The mathematically continuous arrangement minimizes nozzle blockage in the actuator.
