Abstract: Methods and devices for emitting volatile materials are disclosed. In some embodiments, methods and devices for emitting two or more fragrance compositions are disclosed. In one non-limiting embodiment of a device, the device has a housing, and the housing is supported on an electrical outlet by a plug at least indirectly joined to the housing. The device contains a first volatile composition and a second volatile composition. The first volatile composition is emitted in an alternating period relative to said second volatile composition. In one embodiment of the method, the volatile compositions are alternately emitted during periods that are greater than 15 minutes and less than 2 hours.

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 0.0001 grams/second to about 1.2 grams/second. 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.

Abstract: A delivery system and methods for generating droplets of liquid active materials, such as a perfume, air freshener, insecticide formulation, and volatile materials, to the atmosphere by means of a electromechanical transducer. The electromechanical transducer employs a first period of activation and a second period of deactivation to increase the distribution of volatile materials contained within the liquid active materials to the atmosphere and reduce the hedonic habituation of the user. The electromechanical transducer is configured to improve flow rate and decrease deposition of the droplets on to nearby surfaces.

Abstract: The present invention relates to a hard surface cleaning composition comprising a copolymer, wherein said copolymer comprises a zwitterionic unit A or a mixture thereof and another unit B or a mixture thereof, wherein said unit A comprises a betaine group or a mixture thereof and wherein said betaine group of said unit A is a sulphobetaine group or a mixture thereof, and wherein said unit B is derived from vinyl-pyrrolidone.
