Abstract

A potent cosmetically active material such as a perfume is delivered to the body by electrostatic spraying. The active material can be sprayed at ultra-low flow rates, preferably in neat or substantially neat form.

Claims

1. A method for a user to deliver a potent cosmetically active material as a cosmetic to the user'"'"'s body, comprising the user electrostatically spraying from a hand held apparatus said material onto the user'"'"'s body, the cosmetically active material being a perfume, and the method further comprising:

(a) providing an apparatus which includes;

(i) a reservoir containing the potent cosmetically active material to be delivered which is in an electrostatically sprayable form;

(ii) at least one delivery means which is a nozzle in communication with the reservoir;

(iii) a high voltage generator generating voltage in the range 2 to 12 kilovolts powered from an electricity source;

(iv) control means for selectively applying the high voltage from the generator to the at least one delivery means; and

(b) actuating the said control means to electrostatically spray the potent cosmetically active material from the at least one delivery means onto the body at an intended site.
