Abstract: Described is a human epidermal and/or human hair treatment composition of (i) fragrance and/or malodour counteractant and (ii) fragrance- and/or malodour counteractant-compatible solvent-containing microcapsules provided in a suspension gel or emulsion. Also described is a method for delivery of fragrance and beneficial agents to the human epidermal surface area region treatment and/or human hair treatment wherein the microcapsules remain on the human epidermis and/or on the hair follicles for a substantial period of time subsequent to their application and the microcapsules are ruptured over a period of time, thereby effecting both an initial delivery of fragrance and beneficial agent subsequent to rubbing, and, in addition, a controlled release of fragrance and beneficial agents into to the treated human epidermis and/or hair follicles.

Abstract: Apparatus and methods for fragrance sensory stimulation connected to a multimedia source that has at least one audiovisual signal connected to an audiovisual display, and also has fragrance information synchronized with the audiovisual signal is disclosed. In preferred embodiments, a fragrance generator processes the fragrance information into a fragrance signal and at least one fragrance control system accepts a fragrance signal as an input, and generates a control signal and a burst of compressed gas. In turn, a fragrance delivery system preferably comprising a plurality of fragrance chemicals in communication with the burst of compressed gas selectively volatilizes the fragrance chemicals so that a short burst of fragrance is sensed by the subject. Preferably, this short burst is followed by a purging burst that clears the fragrance so that another subsequent fragrance is easier to sense. The compressed gas may be generated by a source of compressed gas or a compressor.
