Abstract: A composition used in combination with an electrohydrodynamic device capable of delivering an active ingredient to the aerodigestive system of the user. The composition comprises three or optionally four basic components: an active ingredient; a carrier material in which the active ingredient may be dissolved, suspended, or emulsified; an aerosol properties adjusting material which provides the composition with the physical characteristics required to create an aerosol cloud by electrostatic or electrohydrodynamic means; and optionally at least one excipient that further adjusts, preserves, stabilizes, or enhances the overall performance of the composition.

Abstract: A electrohydrodynamic aerosol sprayer wherein a gas flow deflector is used for creating a gas flow past the spray nozzle to stabilize the Taylor cone and to transport at least a portion of the aerosol away from the region downstream of the spray nozzle. This stabilization of the cone and transport of aerosol improves the droplet size and distribution and may also reduce the deposit of droplets on the internal components of the device.
