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.
