Patent number: 7226607Abstract: Compositions for providing controlled-release of an active material comprise a dispersant and microcapsules containing the active material and a stabilizer. The compositions contain the dispersant and/or microcapsules at relatively low levels to avoid negatively impacting the surfaces treated with the compositions. The active material is preferably a perfume and the composition provides a controlled-release scent, along with controlling malodor when the compositions further comprise optional odor control agent. The stabilizer improves the stability of the microcapsule. Methods of providing a controlled-release of an active material on a surface comprise the step of contacting the surface with a composition comprising a dispersant and microcapsules containing an active material and a stabilizer.Type: GrantFiled: September 9, 2004Date of Patent: June 5, 2007Assignee: The Procter & Gamble CompanyInventors: Hirotaka Uchiyama, Jonathan Robert Cetti, Mario Alonso, Christine Marie Readnour, Zaiyou Liu, Carl Eric Kaiser, Michele Denise Shirley, Daniel Scott Cobb
