Abstract: The present invention is directed to a process for preparing a capsule product through the increase in the polymerization cure temperature and cure time during the capsule-making process. The microcapsule products prepared according the process of the present invention exhibit enhanced retention of active materials in consumer products which promote instability.

Abstract: The invention in its various embodiments provides a microcapsule product with reduced levels of formaldehyde. Formaldehyde levels are reduced by the inclusion of a formaldehyde scavenger.

Abstract: A polymeric encapsulated fragrance is disclosed which is suitable for use in personal care and cleaning products. In a preferred embodiment of the invention, the fragrance is encapsulated by a first polymer material to form a fragrance encapsulated polymer, the polymer encapsulated shell is then coated with a mixture of cationic polymers, in a preferred embodiment the coating polymers are a reaction product of polyamines and (chloromethyl) oxirane or (bromomethyl) oxirane.

Abstract: A system for fragrance sensory stimulation synchronized to a multimedia source connected to an audiovisual display is disclosed. A fragrance generator processes fragrance information from the audiovisual source into a flagrance signal, and a fragrance control system accepts the fragrance signal as an input and generates a control signal and a controlled airflow. In turn, a fragrance delivery system with a plurality of fragrance chemicals in communication with the controlled airflow selectively volatilizes the fragrance chemicals so that a short burst of fragrance is delivered to a user. In certain embodiments, the fragrance delivery system comprises an indexing turret containing a plurality of ports, each containing one fragrance chemical. In another preferred embodiment, a multi-port micro-valve or an array of such valves contains an absorbent material impregnated with a fragrance in each port.

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.

Abstract: Described is a method for imparting a substantive fragrance to fabrics being washed or dried in a washing machine or clothes dryer by means of tumbling the fabrics with one or more sachets, each of which contains fragrance-containing particles. The polymer particles comprise an ethylene-vinyl acetate copolymer, a blend of polyethylene and an ethylene/vinyl acetate copolymer, an ester-terminated polyamide, a blend of an ester-terminated polyamide and a polysaccharide and/or a C1–C4 alkyl methacrylate polymer. A method for producing fragrance-containing particles is also disclosed.

Abstract: Apparatus and methods for signaling an event using fragrance are disclosed. A fragrance emitting device is activated to a low battery voltage indicator in an electronic device, serving as a warning to replace the battery, either in place of or complimentary to conventional indicators such as warning lights or audible signals. The fragrance emitting system can be integrated into the electronic device itself or can be part of the battery.

Abstract: A particle composition comprising a water-soluble carrier such as starch, a structuring agent such as an ester terminated polyamide and fragrance or flavor is disclosed. Methods of making and using the particles are also disclosed. The particles are desirable for providing fragrance to various products such as powdered detergents.

Abstract: A particle composition containing a continuous phase of 5-95% organically soluble cellulosic material selected from the group consisting of ethyl cellulose and hydroxypropyl cellulose dissolved in 5-95% organic fragrance chemicals and organic flavor chemicals. The particles are formed from a continuous phase product that results from dissolving the cellulosic material in the flavor/fragrance which is subsequently subjected to techniques to form the desired particle size. Methods of making and using the particles are also disclosed.
