A method and product for producing a soft sounding aerosol spray from a particulate suspension, said method and product involving a spray channel having an exit orifice of internal diameter of from 0.5 to 0.8 mm and a terminal section leading to the exit orifice of internal diameter from 0.5 to 0.8 mm for a length of 5 mm or greater, the terminal section of the spray channel including the exit orifice having a tubular internal surface free from obstacle.

Aerosol spray production

The design of the spray nozzle in an aerosol dispenser controls the characteristics of the spray that is produced. In a nozzle that comprises the elements of a multiplicity of inlet channels leading to a swirl chamber and an outlet orifice, the perception of wetness of a spray, such as an aqueous alcoholic deodorant spray, can be reduced by dimensioning the respective elements so that the sum of the widths of the inlet channels is less than the diameter of the swirl chamber and at least 1.5 times the diameter of the outlet orifice and the outlet orifice has a diameter of at least 0.3 mm together with the inlet channels being short, such as less than 0.5 mm. The new nozzle is especially suitable for spraying compositions having a low volatile organic carbon content and compositions comprising a significant proportion of water.
