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.
