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 (including 1H-imidazole) and (chloromethyl) oxirane or (bromomethyl) oxirane.

Encapsulated fragrance chemicals

Described is a multiple (2-4)-compartment fluidic individually stable pre-storable composition storage and unstable mixture-forming and delivery container having separate compartments each communicating with a single mixing zone via an externally-located fluidic composition multiple delivery tube system juxtaposed with the outer surfaces of the compartment walls. These containers are well suited for storing and transporting compositions such as a cleaning agent composition, a personal care composition, an aqueous liquid detergent composition and/or a fabric softening composition and then promptly delivering the resulting unstable mixture to the desired location. The container has been advantageously found to deliver unstable mixtures which could include aqueous suspensions of microencapsulated fragrances or other ingredients.

Multi-compartment storage and delivery containers and delivery system for microencapsulated fragrances

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 cationic polymer, preferably a cationic starch and guar.

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.
