Knock-down spraying canister, electrostatic spray device and method for protecting skin

An electrostatic spraying device being configured and disposed to electrostatically charge and dispense a liquid composition from a supply to a point of dispersal, wherein the device comprises:a reservoir configured to contain the supply of liquid composition;a nozzle to disperse the liquid composition, the nozzle being disposed at the point of dispersal;a channel disposed between the reservoir and the nozzle, wherein the channel permits the electrostatic charging of the liquid composition upon the liquid composition moving within the channel;a high voltage power supply electrically connected to the power source; anda high voltage electrode electrically connected to the high voltage power supply, wherein a portion of the high voltage electrode is disposed between the reservoir and the nozzle, and wherein the high voltage electrode electrostatically charges the liquid composition within the channel at a charging location,wherein the nozzle pathway comprises an outlet path disposed adjacent to the nozzle, the outlet path having a diameter of from about 0.1 mm to about 1 mm and being a point or having a length of from about 0 mm to about 5 mm, and a main path disposed between the outlet path and the charging location, the main path having a diameter greater than the outlet path to about 5 mm and being straight or outwardly tapered towards the charging location at an angle of from about 0 to about 10 degrees.
