Patent number: 5188753Abstract: Perfume particles comprise perfume dispersed within certain water-soluble polymeric carrier materials and encapsulated in a protective shell by coating with a friable coating material. The coated particles allow for preservation and protection of perfumes which are susceptible to degradation or loss in storage and in harsh cleaning conditions. In use, the surface coating fractures and the underlying carrier/perfume particles efficiently deliver a large variety of perfume types to fabrics or other surfaces.Type: GrantFiled: June 21, 1991Date of Patent: February 23, 1993Assignees: The Procter & Gamble Company, Minnesota Mining & MAanufacturing CompanyInventors: Diane G. Schmidt, Howard J. Buttery, Robert J. Norbury
