A method of reducing the droplet size of a composition sprayed from an aerosol spray device comprising a compressed gas propellant, which method comprises imparting a unipolar charge to the liquid droplets by double layer charging during the spraying of the liquid droplets from the aerosol spray device, the unipolar charge being at a level such that the said droplets have a charge to mass ratio of at least +/- 1 x 10 -4 C/kg.
La présente invention concerne un procédé permettant de réduire la taille des gouttelettes d'une composition pulvérisée par un pulvérisateur aérosol comprenant un gaz comprimé comme propulseur, lequel procédé consiste à conférer une charge unipolaire aux gouttelettes de liquide par charge double couche tandis que les gouttelettes de liquide sont pulvérisées depuis le pulvérisateur aérosol, la charge unipolaire se situant à un niveau tel que les gouttelettes présentent une charge spécifique de masse d'au moins +/- 1 x 10<-4> C/kg.
