Abstract: A volatile material delivery system for emitting or releasing volatile materials to the atmosphere is provided. More specifically, delivery systems for delivering one or more volatile materials having perfume components where at least about 40 weight percent of the perfume components have a Kovat's Index of 1500 or more, are also provided.

Abstract: 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.
