Abstract: An oil containing starch granule is provided comprising: (a) a starch to form an effective matrix for said granule; (b) a perfume oil comprising ingredients having a calculated Clog P of at least 3, said Clog P being the calculated octanol to water partition coefficient, said perfume oil being capable of providing a benefit-additive to a substrate upon contact therewith, said substrate being selected from the group consisting of fabrics, hard surfaces, hair and skin; and (c) an effective amount of an organic compound for inhibiting the migration of said oil to the surface of said starch granule, said compound being represented by the following structure: wherein R1 and R2 are each independently, H or: (a) C1-C22 alkylenecarboxy moiety having the formula —(CH2)eR3 wherein R3 is —NHCOR4; or —COR4; or —NR5COR4; and wherein R4 and R5 are each independently C1-C22 alkyl or alkenyl; and e is an integer from 1 to 22; or (b) C1-C22 linear or branched alkyl; or (c) C1-C22 linear or branched alkenyl; or (d) C2

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.

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 controlled airflow. In turn, a fragrance delivery system preferably comprising a plurality of fragrance chemicals in communication with the controlled airflow, selectively volatilizes the fragrance chemicals is so that a short burst of fragrance is sensed by the subject. In certain embodiments, the fragrance delivery system comprises an indexing turret containing a plurality of ports, each port containing one of said plurality of fragrance chemicals.

Abstract: The present invention is directed to encapsulated fragrance materials. The fragrance materials are comprised of high Clog P materials or high Clog P fragrance materials along with high Clog P solvent materials. The encapsulated fragrance and solvent materials can then be further coated with a second coating, preferably a cationic coating. The selective use of solvents enables the fragrance and fragrance materials to remain in the capsules for extended periods of time without leaching from the capsule. The leaching of the flavor or fragrance materials is a problem especially in products that contain a high loading of surfactant or emulsifying materials such as laundry and oral care products.

Abstract: Described is a process for imparting a fragrance to, and/or eliminating a malodour from solid or semi-solid surfaces through the use of polymeric particles. The polymeric particles have infrastructures composed of ethylene-vinyl copolymers, polymethyl methacrylate, polystyrene and/or ethylcellulose. Also described are aqueous treatment compositions for use in such processes.
