US 2003/0216488 A1 · Compositions comprising a dispersant and microcapsules containing an active material

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.

Dependent claims

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.

7 more elements

An antimicrobial composition for providing controlled-release of an active material and for killing microorganisms on a surface, said composition comprising:

(a) 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;
(c) an effective amount of an antimicrobial active to kill microorganisms on said surface, wherein said antimicrobial active is not contained in said microcapsules;
and
(d) aqueous carrier.
