A device for packaging and applying a substance constituting a cosmetic or a care product containing at least one volatile hydrocarbon solvent can be closed hermetically and includes at lease two elements, at least one of which is made of a plastics material. The elements are suitable for moving relative to each other in order to enable the substance to be applied. The plastics material is selected in such a manner that the element(s) is/are not subject to significant mass variation when put into prolonged contact with the vapor of the solvent.

The invention concerns a new personal spray device pressurized by a gas mixture comprising nitrogen and carbon dioxide for the fine spray dispersion of, for example, liquids or atomizable compositions. The spray device prevents the formation of liquid jet or ion precipitates. Preferably, the spray device contains mineralized waters and controls the pH and the microbial content of the mineralized waters.
