Abstract

An aerosol dispenser assembly is disclosed that includes a container holding a liquid product and a compressed gas propellant for propelling the liquid product from the container. A design methodology for the actuator body and swirl nozzle insert is disclosed for maintaining a small particle size or Sauter Mean Diameter (D[3, 2]) of less than 48 μm at a suitable spray rate (1.5-2 g/s), while utilizing a compressed gas VOC-free propellant for an air freshener product. As obtaining reduced particle size to compete with LPG propellants may result in a reduced spray rate, it is anticipated that one or more nozzles may be designed into the actuator body to maintain a suitable spray rate.
