Method of freshening air
Abstract:
Air freshener products and methods for freshening air are disclosed. In some embodiments, the air freshening product may include a container for storing an air freshening composition that may contain compressed gas such as compressed air, nitrogen, nitrous oxide, inert gases, or carbon dioxide. When the container is completely filled with propellant and air freshening composition, the air freshening composition may be released from the container at a flow rate of from about 0.8 grams/second to about 1.5 grams/second, wherein the mean particle size of the released spray droplets is from about 10 microns to about 100 microns.The method of freshening air, in certain embodiments, provides improved delivery of an air freshening composition using a non-hydrocarbon propellant. If malodor counteractants are used, the method may also provide a reduction in malodors.
