Compositions comprising a dispersant and microcapsules containing an active material
First Claim
1. A non-aerosol composition for providing controlled-release of an active material, said composition comprising:
- (a) from about 0.001% to about 1%, by weight of said composition, of microcapsules containing at least one of the following;
(i) an active material; and
(ii) an optional encapsulated odor control agent;
wherein said active material and said optional odor control agent may be contained in the same microcapsules;
in different microcapsules;
or both, (b) a dispersant; and
(c) aqueous carrier.

Abstract
Compositions for providing controlled-release of an active material comprise a dispersant and microcapsules containing the active material. 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. 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.
